<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to seize any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft and personnel. If an X-Com base tile containing the 'person' icon is destroyed, that base's personnel may be killed as a result.<br />

* Bombing fleets appear from Week 4 onwards.<br />
<br />
==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders). There is some debate as to whether the scanning beam has the ability to instantly infiltrate an organization when their building is scanned or not, leading to infamous possible misnomer 'micronoid rain' for the beam.<br />

<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to seize any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft and personnel. If an X-Com base tile containing the 'person' icon is destroyed, that base's personnel may be killed as a result.<br />

==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders).<br />

<div>==Inaccuracy?==<br />
I've just seen a fleet which is 665444. This doesn't appear anywhere on this page. It performs infiltration and seems to be the favoured alien fleet during week 4 if the aliens have all their ships (i.e. many of types 1-6). My guess is a typo in infiltration fleet 12.

Air Raid? I'm going to test this with "Apocalypse Missions 100%" (Apoc'd) at the start with 5 craft of each available. What they do I think is just bomb a building to flatten it. I don't think a base assault is an air-raid since that falls under Infiltration.... it just so happens that the infiltration is a "your ownership building" chosen at random. [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
:[[User:Darkpast]] suggested that name over "bombing" when we discussed it on another talk page. "Air raid" means bombing IRL. Also, base defences can occur either randomly from an infiltration mission, or from what's (incorrectly) been referred to as a "micronoid rain mission" - it's actually a scanning beam and once they've found your base every subsequent instance of this mission will drop aliens into it.

:: I just tested the above and the alien ships behave exactly like I'd expected. They flatten any building at random since I made sure to have every AI corp at neutral with aliens. Ahh, I just worked out that Air Raid has a slightly different meaning to what we though it was. The joys of language barriers and a global community. Thanks for the explanation. [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
== Confusing Page Structure ==<br />
This page isn't really thought out properly. Micronoid Rain what is it and how its changed or why is it changed since everyone knows about the blue rain and that what it was always called. Where is it ufopedia with explaination on changes of the rain? Base Assault or Raiding (or should it be called base invasion?) Is that a bombing (explosions and leveling) or landing raid (like landing an overwhelming force)?<br />
<br />
Apoclaypse? hmm, yeah they send all at once but what do you call cityscape destruction bombing? An air RAID? but isn't raid a battlescape fight and not a bombing run?<br />
<br />
Gets confusing with BASE bombing/assault or air raid... yeah they land a force but it isn't a force! ...its a bombing run (they shouldn't be labeled similar). Gives me headache.<br />
<br />
:A good part of the confusion is because the Apocalypse section of the wiki is currently undergoing spring cleaning. See the discussion here for more info: [[Talk:Alien_Infiltration_(Apocalypse)]] <br />
:Also, the term "Micronoid Rain" was thought up by the community. It's not used in-game or even in the game files, and it's actually wrong - the UFOs are not dropping Micronoids, but searching for X-COM bases. [[User:Darkpast|Darkpast]] ([[User talk:Darkpast|talk]]) 12:08, 30 July 2020 (UTC)<br />
<br />
:: "Micronoid Rain" is like TFTD's "USO", which wasn't in the game but coined by the players for convenience. It has become part of the gaming vocabulary by virtue of long term use. I believe it does need to be acknowledged at the very least. Mainly to explain why it is incorrect now and to put it into context. <br />
<br />
::With so little information about what was happening under the hood in the past, you can imagine the thought process of how the term may have come into existence by players discussing shared experiences and correlating a series of coinciding events together.

<br />
:::Alright, fine. I'll give full descriptions of each mission here and we can discuss names.<br />
<br />
:::1) UFOs drop aliens into random buildings with the grey tube. If it happened to be your base, base attack mission. Otherwise, there are now aliens in the city causing alien infiltration. Starts at Week 1, and is the only mission for weeks 1-3.<br />
<br />
:::2) UFOs attack buildings (belonging to someone the aliens don't like) with vehicle weapons. Starts at Week 4.<br />
<br />
:::3) UFOs scan random structures with a blue "rain"-like scanning beam. If a structure contains an X-COM base, every following mission of this type diverts a UFO to drop aliens into that base (base attack mission). Only effect on other structures is that sometimes the structure owner will get mad and scramble craft to attack the UFO. Starts at Week 5.<br />
<br />
:::4) Mothership (it's always a Mothership) drops an Overspawn into the city. Allegedly starts at Week 7, but there won't be any Motherships to do it until Week 8.<br />
<br />
:::Go nuts. Suggest better names. I put in what Darkpast and I thought up for #2 and #3 and I wasn't too happy with them either, so if someone has a better idea I'm all ears. #2 and #3 were previously titled "Attack" and "Subversion" respectively, but those names are not acceptable; all missions except #1 are forms of attack, so #2 needs to be more specific, and #3 doesn't subvert anything so calling it "Subversion" (or "Micronoid Rain") is blatantly wrong.<br />
<br />
:::I'm planning on overhauling the Cityscape Fighting page to describe these missions, incidentally. I just haven't gotten around to it. [[User:Magic9mushroom|Magic9mushroom]] ([[User talk:Magic9mushroom|talk]]) 02:10, 1 August 2020 (UTC)<br />
<br />
:::: I hope i can help things moving along. This is my suggestion:<br />
:::: I can't think of a title right now maybe "Mission Types and Actions" or something. It can't be alien specific becuase it mentions corps as well.<br />
:::: 1 This is obviously called Infiltration Mission and is thus titled within each corps page ingame pedia. Infiltration is suited because it is the most common thing in (the manual) what the aliens are doing. Infiltration of micronoid slime via a cloud-tube mechanism action when hovering briefly over a building (should place a GIF of the animation here). If the building happens to have an X-com facility (notice I didn't mention '''base''' here) when the aliens perform their infiltration action then it immediately become a Base Defense mission.<br />
:::: 2 Base Defense Mission. An xcom facility has come under attack from hostile forces. An X-com base has been invaded and must be defended with your troops (could be a pic here of the defense screen with the griffon tank). The hostiles could be aliens or a corporation hostile to X-Com. When aliens attack, you'll will see the cloudlike tube over your base from any alien craft. When corprotions attack, you have no warning and have no way to prevent it. Be prepared to defend all your bases with security (pic here of a security turret room and hotlink) and armed troops. Techniqcal personel cannot defend a base even with turrets. You must have stationed troops. When X-Com raids another corportion then X-com is the agressor and the target is performing a Base Defense Mission. (hotlink stun raid - my baby)"<br />
:::: 3 Bombing Mission. A blurb within the new descriptions should include something like "... this mission style is basically cityscape destruction to shoot and bomb the external building to cause it to collaspe, and for economic damage (could be a pic here of a bombber shooting a disruptor missile which is at mid collaped at a building but '''not''' an xcom base). If a X-Com building happens to be the target, then it is possible that the base within could be destroyed (pic of lose screen here possibly). A Bombing Mission can be preformed by any alien craft, not just the Bomber (hot link here to bomber, no pic necesaary). If a corporation is sufficently hostile to another then a "Illigal Flyer detected" will commence to bomb the chosen external building. (hot link to corpoation relations here)" I don't think having another subtitle for Illegal Flyer would be needed since it strictly is a bobming mission abeit suicidal.<br />
:::: 4 Micronoid Rain (obviously because that is what it looks like but not what is it). This blurb should be noted as first thing after the subtitle. "Micronoid Rain is a blue "rain" which falls from an alien craft when hovering over a building (animated pic here). Once commonly believed to be an attempt by Aliens to directly control the target corporation by immediate and total Infiltration (that is, an immediatel 100% infiltraion level) regardless of actual infiltration. The real purpose of the rain is to scan the building for an X-com base. If an x-com facilty (not callig it base here) is located then the aliens will, in the near future, perform an Infiltration Mission ie: a Base Defense mission will be coming soon!<br />
:::: 5 Overspawn Drop. Aliens will drop this large creature from a Mothership yadda no complaints here!<br />
<br />
:::: I don't like calling a Base Defense Mission a 'Base Raid' or calling a Bombing Mission an 'Air Raid' because there is an actual mission performed which of course is "Raid Corporation". Confusing can result.<br />
<br />
:::: THIS IS A spilling meatsteak brain diareahhhhha. I don't have the capability to insert images and I'll probably arse it up anyways. I'm small fry compared to you all here and someone who doesn't have to deal with the unwashed Whu-Flu masses running around like sneezy headless (blue?) chickens will do a better job than me. [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
:::The plan is to have separate pages for X-Com mission types, corp actions and alien actions, the first for obvious reasons and the latter two because they have separate generation mechanisms. The first is already up at [[Tactical Combat Missions (Apocalypse)]].<br />
<br />
:::Base Defence (or as the manual calls it, Base Attack) is not a separate alien action; it's a possible consequence of two separate alien acts (each of which have their own characteristic UFO composition and mission likelihood) as well as a possible corporate action. Using my earlier numbering, the result of a #3 finding your base isn't a new mission; rather, any further #3 missions will include one UFO dropping aliens into your base. You can also get a Base Attack from a #1, but from the aliens' point of view that's a completely-different thing (and it will frequently involve different UFOs as well).<br />
<br />
:::I am absolutely opposed to calling #3 Micronoid Rain. It doesn't look like Micronoids; it was only called that because people thought it mind-controlled organisations and that would imply dropping Micronoids. It doesn't control organisations, therefore calling it Micronoid Rain is confusing and wrong. We can mention the "Micronoid Rain" myth in a footnote, but it cannot be the name of the mission. [[User:Magic9mushroom|Magic9mushroom]] ([[User talk:Magic9mushroom|talk]]) 06:34, 4 August 2020 (UTC)<br />
<br />
:: Then what is the mission to be called which just about everyone who went to any forum over the years to discuss what that blue rain is? The cat is out of the bag and you cannot undo thousands of forum posts which novice players will look to when having questions - eventually micronoid rain will pop up. Micronoid Rain is what it is known to be called. Its completely wrong but everyone uses it hence, that immediate blurb about what it actually is. Kevlar is a known name. Aramid is its actual name. How many people have actually heard of Aramid? Micronoid Rain is its known name.... [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
: It's certainly what it has been known by. I've called it by that. However I do think a more fitting term would be better if one can be decided on. By the way I've only really caught the whole Micronoid Rain thing on the tail end. Was the test on the blue beam done to see if there was an immediate alliance flip, or was some time allowed after that to observe the behaviour of the affected company? [[User:NKF|NKF]] ([[User talk:NKF|talk]]) 10:22, 4 August 2020 (UTC)<br />
<br />
:: Why not simply have a redirect entitled "Micronoid Rain" that takes the user to the properly-named page? <br />
:: Btw, the term "Blue rain" has also been used to describe the alien beam. I still have no good idea for a proper name for the mission, though. "Retaliation" isn't good because bombing and Overspawn are also forms of retaliation. "Scan" doesn't sound right, either.<br />
:: As for the bombing - I guess "Bombing Mission" or "Bombing Run" would be better than "Air Raid", then, for the reasons EsTeR suggests. "Infiltration" or "Infiltration Mission" and "Overspawn Drop" sound good for the remaining two alien missions. [[User:Darkpast|Darkpast]] ([[User talk:Darkpast|talk]]) 17:44, 4 August 2020 (UTC)<br />
<br />
:::@NKF: I did a whole bunch of tests myself, with no insta-flips regardless of infiltration%, but the reason I'm sure is because the OpenApoc people (in particular Skin36) have decompiled Apocalypse and he told me it doesn't flip organisations but rather looks for your base. My testing confirmed that if they find your base, subsequent missions of that type will always drop in. I'm not saying his interpretation of code is perfect - I've worked with him on this in a few other issues to nut out what the code's actually doing - but any org flip code should be blindingly obvious.<br />
<br />
:::@Darkpast: "Search&Raid"? Clunky, but gets the point across IMO. [[User:Magic9mushroom|Magic9mushroom]] ([[User talk:Magic9mushroom|talk]]) 04:24, 5 August 2020 (UTC)<br />
<br />
:: Search and Destroy. I think it works. Its cheesy and doesn't really have mystique to it... but thats what the aliens are really doing! I think everyone had a suspicion that the blue rain dodn't work over the twenty something years this game is been out, but only with editors were some finer details able to be changed to test things out - short of decompiling the exe(s) which is a grey area legally. Oh no... grey area... I'll see myself out, LOL [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
:::I'd avoid the word "Raid" because it is already used to describe attacks on other organisations ("Raid Building", "Organization raided" etc.). As EsTeR says, "Search and Destroy" has a certain ring to it; the only other name I can think of is "Search and Assault". [[User:Darkpast|Darkpast]] ([[User talk:Darkpast|talk]]) 06:58, 6 August 2020 (UTC)<br />
<br />
I've added descriptions to the mission types and renamed 'Air Raid' to 'Bombing' to help clear up the (correctly identified) confusing structure of the page. Feel free to edit the wording where necessary, though please don't just undo the changes if you don't agree with them. Hope it helps!

I've added descriptions to the mission types and renamed 'Air Raid' to 'Bombing' to help clear up the (correctly identified) confusing structure of the page.

<hr />
<div>==Inaccuracy?==<br />
I've just seen a fleet which is 665444. This doesn't appear anywhere on this page. It performs infiltration and seems to be the favoured alien fleet during week 4 if the aliens have all their ships (i.e. many of types 1-6). My guess is a typo in infiltration fleet 12.

<br />
==Naming==<br />
<br />
Air Raid? I'm going to test this with "Apocalypse Missions 100%" (Apoc'd) at the start with 5 craft of each available. What they do I think is just bomb a building to flatten it. I don't think a base assault is an air-raid since that falls under Infiltration.... it just so happens that the infiltration is a "your ownership building" chosen at random. [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
:[[User:Darkpast]] suggested that name over "bombing" when we discussed it on another talk page. "Air raid" means bombing IRL. Also, base defences can occur either randomly from an infiltration mission, or from what's (incorrectly) been referred to as a "micronoid rain mission" - it's actually a scanning beam and once they've found your base every subsequent instance of this mission will drop aliens into it. [[User:Magic9mushroom|Magic9mushroom]] ([[User talk:Magic9mushroom|talk]]) 08:48, 29 July 2020 (UTC)<br />
<br />
:: I just tested the above and the alien ships behave exactly like I'd expected. They flatten any building at random since I made sure to have every AI corp at neutral with aliens. Ahh, I just worked out that Air Raid has a slightly different meaning to what we though it was. The joys of language barriers and a global community. Thanks for the explanation. [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
== Confusing Page Structure ==<br />
This page isn't really thought out properly. Micronoid Rain what is it and how its changed or why is it changed since everyone knows about the blue rain and that what it was always called. Where is it ufopedia with explaination on changes of the rain? Base Assault or Raiding (or should it be called base invasion?) Is that a bombing (explosions and leveling) or landing raid (like landing an overwhelming force)?<br />
<br />
Apoclaypse? hmm, yeah they send all at once but what do you call cityscape destruction bombing? An air RAID? but isn't raid a battlescape fight and not a bombing run?<br />
<br />
Gets confusing with BASE bombing/assault or air raid... yeah they land a force but it isn't a force! ...its a bombing run (they shouldn't be labeled similar). Gives me headache.<br />
<br />
:A good part of the confusion is because the Apocalypse section of the wiki is currently undergoing spring cleaning. See the discussion here for more info: [[Talk:Alien_Infiltration_(Apocalypse)]] <br />
:Also, the term "Micronoid Rain" was thought up by the community. It's not used in-game or even in the game files, and it's actually wrong - the UFOs are not dropping Micronoids, but searching for X-COM bases. [[User:Darkpast|Darkpast]] ([[User talk:Darkpast|talk]]) 12:08, 30 July 2020 (UTC)<br />
<br />
:: "Micronoid Rain" is like TFTD's "USO", which wasn't in the game but coined by the players for convenience. It has become part of the gaming vocabulary by virtue of long term use. I believe it does need to be acknowledged at the very least. Mainly to explain why it is incorrect now and to put it into context. <br />
<br />
::With so little information about what was happening under the hood in the past, you can imagine the thought process of how the term may have come into existence by players discussing shared experiences and correlating a series of coinciding events together. [[User:NKF|NKF]] ([[User talk:NKF|talk]]) 05:53, 31 July 2020 (UTC)<br />
<br />
:::Alright, fine. I'll give full descriptions of each mission here and we can discuss names.<br />
<br />
:::1) UFOs drop aliens into random buildings with the grey tube. If it happened to be your base, base attack mission. Otherwise, there are now aliens in the city causing alien infiltration. Starts at Week 1, and is the only mission for weeks 1-3.<br />
<br />
:::2) UFOs attack buildings (belonging to someone the aliens don't like) with vehicle weapons. Starts at Week 4.<br />
<br />
:::3) UFOs scan random structures with a blue "rain"-like scanning beam. If a structure contains an X-COM base, every following mission of this type diverts a UFO to drop aliens into that base (base attack mission). Only effect on other structures is that sometimes the structure owner will get mad and scramble craft to attack the UFO. Starts at Week 5.<br />
<br />
:::4) Mothership (it's always a Mothership) drops an Overspawn into the city. Allegedly starts at Week 7, but there won't be any Motherships to do it until Week 8.<br />
<br />
:::Go nuts. Suggest better names. I put in what Darkpast and I thought up for #2 and #3 and I wasn't too happy with them either, so if someone has a better idea I'm all ears. #2 and #3 were previously titled "Attack" and "Subversion" respectively, but those names are not acceptable; all missions except #1 are forms of attack, so #2 needs to be more specific, and #3 doesn't subvert anything so calling it "Subversion" (or "Micronoid Rain") is blatantly wrong.<br />
<br />
:::I'm planning on overhauling the Cityscape Fighting page to describe these missions, incidentally. I just haven't gotten around to it. [[User:Magic9mushroom|Magic9mushroom]] ([[User talk:Magic9mushroom|talk]]) 02:10, 1 August 2020 (UTC)<br />
<br />
:::: I hope i can help things moving along. This is my suggestion:<br />
:::: I can't think of a title right now maybe "Mission Types and Actions" or something. It can't be alien specific becuase it mentions corps as well.<br />
:::: 1 This is obviously called Infiltration Mission and is thus titled within each corps page ingame pedia. Infiltration is suited because it is the most common thing in (the manual) what the aliens are doing. Infiltration of micronoid slime via a cloud-tube mechanism action when hovering briefly over a building (should place a GIF of the animation here). If the building happens to have an X-com facility (notice I didn't mention '''base''' here) when the aliens perform their infiltration action then it immediately become a Base Defense mission.<br />
:::: 2 Base Defense Mission. An xcom facility has come under attack from hostile forces. An X-com base has been invaded and must be defended with your troops (could be a pic here of the defense screen with the griffon tank). The hostiles could be aliens or a corporation hostile to X-Com. When aliens attack, you'll will see the cloudlike tube over your base from any alien craft. When corprotions attack, you have no warning and have no way to prevent it. Be prepared to defend all your bases with security (pic here of a security turret room and hotlink) and armed troops. Techniqcal personel cannot defend a base even with turrets. You must have stationed troops. When X-Com raids another corportion then X-com is the agressor and the target is performing a Base Defense Mission. (hotlink stun raid - my baby)"<br />
:::: 3 Bombing Mission. A blurb within the new descriptions should include something like "... this mission style is basically cityscape destruction to shoot and bomb the external building to cause it to collaspe, and for economic damage (could be a pic here of a bombber shooting a disruptor missile which is at mid collaped at a building but '''not''' an xcom base). If a X-Com building happens to be the target, then it is possible that the base within could be destroyed (pic of lose screen here possibly). A Bombing Mission can be preformed by any alien craft, not just the Bomber (hot link here to bomber, no pic necesaary). If a corporation is sufficently hostile to another then a "Illigal Flyer detected" will commence to bomb the chosen external building. (hot link to corpoation relations here)" I don't think having another subtitle for Illegal Flyer would be needed since it strictly is a bobming mission abeit suicidal.<br />
:::: 4 Micronoid Rain (obviously because that is what it looks like but not what is it). This blurb should be noted as first thing after the subtitle. "Micronoid Rain is a blue "rain" which falls from an alien craft when hovering over a building (animated pic here). Once commonly believed to be an attempt by Aliens to directly control the target corporation by immediate and total Infiltration (that is, an immediatel 100% infiltraion level) regardless of actual infiltration. The real purpose of the rain is to scan the building for an X-com base. If an x-com facilty (not callig it base here) is located then the aliens will, in the near future, perform an Infiltration Mission ie: a Base Defense mission will be coming soon!<br />
:::: 5 Overspawn Drop. Aliens will drop this large creature from a Mothership yadda no complaints here!<br />
<br />
:::: I don't like calling a Base Defense Mission a 'Base Raid' or calling a Bombing Mission an 'Air Raid' because there is an actual mission performed which of course is "Raid Corporation". Confusing can result.<br />
<br />
:::: THIS IS A spilling meatsteak brain diareahhhhha. I don't have the capability to insert images and I'll probably arse it up anyways. I'm small fry compared to you all here and someone who doesn't have to deal with the unwashed Whu-Flu masses running around like sneezy headless (blue?) chickens will do a better job than me. [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
:::The plan is to have separate pages for X-Com mission types, corp actions and alien actions, the first for obvious reasons and the latter two because they have separate generation mechanisms. The first is already up at [[Tactical Combat Missions (Apocalypse)]].<br />
<br />
:::Base Defence (or as the manual calls it, Base Attack) is not a separate alien action; it's a possible consequence of two separate alien acts (each of which have their own characteristic UFO composition and mission likelihood) as well as a possible corporate action. Using my earlier numbering, the result of a #3 finding your base isn't a new mission; rather, any further #3 missions will include one UFO dropping aliens into your base. You can also get a Base Attack from a #1, but from the aliens' point of view that's a completely-different thing (and it will frequently involve different UFOs as well).<br />
<br />
:::I am absolutely opposed to calling #3 Micronoid Rain. It doesn't look like Micronoids; it was only called that because people thought it mind-controlled organisations and that would imply dropping Micronoids. It doesn't control organisations, therefore calling it Micronoid Rain is confusing and wrong. We can mention the "Micronoid Rain" myth in a footnote, but it cannot be the name of the mission. [[User:Magic9mushroom|Magic9mushroom]] ([[User talk:Magic9mushroom|talk]]) 06:34, 4 August 2020 (UTC)<br />
<br />
:: Then what is the mission to be called which just about everyone who went to any forum over the years to discuss what that blue rain is? The cat is out of the bag and you cannot undo thousands of forum posts which novice players will look to when having questions - eventually micronoid rain will pop up. Micronoid Rain is what it is known to be called. Its completely wrong but everyone uses it hence, that immediate blurb about what it actually is. Kevlar is a known name. Aramid is its actual name. How many people have actually heard of Aramid? Micronoid Rain is its known name.... [[User:EsTeR|EsTeR]] ([[User talk:EsTeR|talk]])<br />
<br />
: It's certainly what it has been known by. I've called it by that. However I do think a more fitting term would be better if one can be decided on. By the way I've only really caught the whole Micronoid Rain thing on the tail end. Was the test on the blue beam done to see if there was an immediate alliance flip, or was some time allowed after that to observe the behaviour of the affected company? [[User:NKF|NKF]] ([[User talk:NKF|talk]]) 10:22, 4 August 2020 (UTC)<br />
<br />
:: Why not simply have a redirect entitled "Micronoid Rain" that takes the user to the properly-named page? <br />
:: Btw, the term "Blue rain" has also been used to describe the alien beam. I still have no good idea for a proper name for the mission, though. "Retaliation" isn't good because bombing and Overspawn are also forms of retaliation. "Scan" doesn't sound right, either.<br />
:: As for the bombing - I guess "Bombing Mission" or "Bombing Run" would be better than "Air Raid", then, for the reasons EsTeR suggests. "Infiltration" or "Infiltration Mission" and "Overspawn Drop" sound good for the remaining two alien missions. [[User:Darkpast|Darkpast]] ([[User talk:Darkpast|talk]]) 17:44, 4 August 2020 (UTC)<br />
<br />
:::@NKF: I did a whole bunch of tests myself, with no insta-flips regardless of infiltration%, but the reason I'm sure is because the OpenApoc people (in particular Skin36) have decompiled Apocalypse and he told me it doesn't flip organisations but rather looks for your base. My testing confirmed that if they find your base, subsequent missions of that type will always drop in. I'm not saying his interpretation of code is perfect - I've worked with him on this in a few other issues to nut out what the code's actually doing - but any org flip code should be blindingly obvious.<br />
<br />
:::@Darkpast: "Search&Raid"? Clunky, but gets the point across IMO. [[User:Magic9mushroom|Magic9mushroom]] ([[User talk:Magic9mushroom|talk]]) 04:24, 5 August 2020 (UTC)<br />

<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

<br />
==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to sieze any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if not left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft.<br />

==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders).<br />

[[Category: Apocalypse]]</div>Frissionhttps://temp.ufopaedia.org/index.php?title=UFO_Incursions_(Apocalypse)&diff=106386UFO Incursions (Apocalypse)2022-02-25T03:28:27Z<p>Frission: /* Overspawn Drop Fleets */</p>
<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to sieze any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if not left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft.<br />

==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders).<br />

<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to sieze any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if not left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft.<br />

==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders).<br />

<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to sieze any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if not left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft.<br />

<br />
==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders). All UFOs involved in a Base Assault/Scanning mission will perform scans; there are no 'escort' ships in this case, despite being usually a mixed fleet.<br />

<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to sieze any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if not left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft.<br />

<br />
==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders). All UFOs involved in a Base Assault/Scanning mission will perform scans; there are no 'escort' ships in this case, despite being usually a mixed fleet.<br />

<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to sieze any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if not left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft.<br />

* Bombing fleets appear from Week 4 onwards.<br />
<br />
==Base Assault Fleets==<br />
<br />
This fleet type is the reason players want to build Security Stations and keep armed personnel to secure X-Com facilities. Base Assault Fleets will spend their time in the city scanning buildings with a sparkling blue scanning beam resembling blue 'rain' with the express purpose of seeking out X-Com facilities. Once located, the aliens will send at least one UFO in all future missions of this type loaded with troops with one singular purpose: Invading and destroying the discovered base. This can be prevented by shooting down any incoming UFOs before they can locate your base, or the troop transport if they've already found it (though it can be an impossible shell game to determine just which primary UFO is the one bringing the invaders). All UFOs involved in a Base Assault/Scanning mission will perform scans; there are no 'escort' ships in this case, despite being usually a mixed fleet.<br />

[[Category: Apocalypse]]</div>Frissionhttps://temp.ufopaedia.org/index.php?title=UFO_Incursions_(Apocalypse)&diff=106381UFO Incursions (Apocalypse)2022-02-25T03:15:01Z<p>Frission: Adding much needed descriptions (edit 2) (Also reorganizing the page in order of appearance)</p>
<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />
<br />
* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
<br />
==Bombing Fleets==<br />
<br />
Likely the second or type of fleet the player will have to contend with (or third depending on luck), 'Bombing' fleets are exactly that - UFOs sent to cause as much destruction to the city, craft and X-Com as possible. These typically consist of primary craft using disruptor bombs or multi-warhead missiles while escorted by Fast Attack or stronger escort ships using medium or larger disruptor beams. On the plus side, players will not have to worry about tactical missions other than to sieze any downed UFOs, as they will not be attempting to deposit troops in buildings. These fleets will remain in the city much longer than infiltration fleets before pulling back to the alien dimension, and can cause massive damage if not left unchecked. While they can be a great source of captured UFOs and technology, a bombing fleet should never be underestimated, as it can pose one of the greatest threats to unprepared X-Com craft.<br />

[[Category: Apocalypse]]</div>Frissionhttps://temp.ufopaedia.org/index.php?title=UFO_Incursions_(Apocalypse)&diff=106379UFO Incursions (Apocalypse)2022-02-25T02:43:45Z<p>Frission: Adding much needed descriptions (edit 1)</p>
<hr />
<div>This page lists the various nuts and bolts of how the game decides which [[Alien Craft (Apocalypse)|Alien Craft]] come out of the [[Dimension Gates]] and what they do once in [[Mega-Primus]].<br />
<br />
Unlike in UFO: Enemy Unknown and X-Com: Terror From the Deep, the [[Aliens (Apocalypse)|Aliens]] in X-COM: Apocalypse do '''not''' have infinite reserves of craft. Rather, the pool of craft in the [[Alien Dimension (Apocalypse)|Alien Dimension]] is tracked, with new UFOs being constructed every Monday (up to a limit) and X-COM interceptions removing craft from the pool.<br />
<br />
Every time an alien mission is scheduled, the game rolls randomly on a table to decide what act they will attempt to perform. This table changes every week. Then, once an act has been selected, the specific UFO makeup of the incursion is chosen deterministically from tables for each possible act depending on what craft are available in the Alien Dimension pool; as reproduced here, the tables increase in priority downward, so the aliens will always use the highest-numbered fleet possible for the chosen mission.<br />
<br />
Some UFOs on the Infiltration and Overspawn Drop tables are listed as "Bombing" craft. These craft will bomb a building, as though on an Air Raid mission.<br />
<br />
Destroying the [[Control Chamber]] building permanently halts the production of alien craft. It also triggers a special incursion not found on these tables - the next time an alien mission is scheduled, '''all''' remaining UFOs (except [[Alien Probe (Apocalypse)|Probes]]) will swarm out of the Dimension Gates and start tearing down Mega-Primus as though on a very large Air Raid mission. This final battle is typically referred to as "the Apocalypse mission".<br />

==[[Alien Infiltration (Apocalypse)|Infiltration]] Fleets==<br />
<br />
These are the standard type of UFO incursion for the majority of the early game, which peters out as the weeks go on in favor of more direct aggression. Infiltration fleets consist of one to three primary craft, usually with escorts to protect them (as seen on the table below). When they appear in Mega-Primus, the primary craft will fly directly to a pre-selected target destination, hover over it for several seconds and attempt to deploy a squad of aliens to infiltrate the building via a transport beam (i.e. 'the grey tube'). Destroying the craft before it reaches its destination will prevent this. If the tube has already appeared, it is possible to prevent the UFO from succeessfully completing its transport by destroying it before the beam has finished. UFOs which successfully deposit their troops will then immediately move to the dimension gates to return to the Alien Dimension, leaving players to have to send squads to investigate those buildings for aliens. If left unchecked, the target organization's infiltration percentage will go up after several hours and the aliens may continue to spread to nearby buildings and organizations, creating an even bigger problem for X-Com over time. When a primary UFO craft for this mission type escapes via the dimension gates, that craft's assigned escort(s) will then immediately attempt to escape as well (this rule holds true for most if not all incursions).<br />

<nowiki>*</nowiki>These fleets will never appear, as the ships required will also fulfil a higher-priority fleet.<br />
<br />
<nowiki>**</nowiki>This fleet can appear as long as the aliens have at least one Battleship and one Escort Ship (though two Battleships will still appear in Mega-Primus). This is the result of a bug in the spawn routine; instead of checking whether there are two Battleships, it checks whether there is one Battleship twice.<br />

* UFO fleets led by [[Alien Transporter (Apocalypse)|Transporters]] or [[Alien Assault Ship (Apocalypse)|Assault Ships]] are always on Infiltration missions.<br />
