			==UFOpaedia description==
			If XCom interceptors are being particularly successful in shooting down UFOs then the aliens may take some retaliatory action. This could result in a direct attack against an XCom base. However, the aliens have to find an XCom base in order to attack it, and provided UFOs are kept away then there should be little danger of an assault.

[[Image:Alien Retaliation.png\|thumb\|right\|Alien Retaliation mission type.]]
			The most overtly aggressive of the [[Alien Missions]], [[Alien Retaliation]] signifies an alien attempt to destroy X-Com via military force. Alien Retaliation missions are generated in response to X-Com's activities, in a form of dynamic difficulty.

	~~An '''Alien Retaliation'''~~ mission ~~consists of~~ a series of ~~UFO scouts that~~ will appear in the ~~area the UFO was shot down to patrol~~ for an X-~~COM~~ base. At the ~~end~~ of the ~~patrol~~, ~~once~~ the ~~aliens have decided that they've ''found'' a base~~, a [[Battleship]] will appear ~~a day~~ or ~~two afterwards and attack an X-COM~~ base in ~~the same region - picking one at random if there are several. In the worst case scenario~~, the ~~aliens will sometimes skip the scouting phase entirely and immediately schedule the attack~~.		The mission is performed in two stages. First, a series of UFOs ([[Small Scout\|Small]], [[Medium Scout\|Medium]] and [[Large Scout]]s, and eventually two [[Battleship]]s) will appear and carefully fly over the targetted zone, searching for an X-Com base. This search can be hampered by shooting down the scouts, or by construction of [[Mind Shield]]s. If the scouts succeed in finding a base, the scouting phase will end, and a [[Battleship]] will appear to assault the base. An attacking Battleship can be destroyed by [[Base Defence Systems]], or (if the base is manned) its strike force can be fought off in a [[Base Defence]] mission; otherwise, the base is destroyed.

	~~Once an X-COM base is marked for the attack, a Battleship will be sent to drop troops into the base, and then immediately escape into orbit. See~~ [[~~#Base Attack Loop~~\|~~below~~]] for a ~~pertinent bug/feature concerning this~~.		The aliens do not [[Scoring\|score]] from this mission beyond the ordinary points for UFO presence; however, losing a base is a direct material blow to X-Com. Furthermore, if X-Com loses all its bases to Alien Retaliation, you will immediately lose the game.

	A ~~battleship on the attack~~ is ~~easy~~ to ~~spot as it~~ will always be ~~moving purposefully~~ in a ~~straight line~~ to the ~~base it~~ is ~~attacking~~. ~~The ship~~ will ~~be moving at top speed so only an~~ [[~~Avenger~~]] ~~can intercept~~ it.		==Causes of Retaliation==
			There are two distinct ways an [[Alien Retaliation]] mission can begin.
			*A "triggered" Retaliation mission is a specific response to a single X-Com act. Every time X-Com shoots down a UFO in air combat, there is a chance (modified by difficulty level) that an Alien Retaliation mission will immediately be generated. Retaliation missions generated in this manner will always be performed by the same race that crewed the UFO shot down, and will be performed either in the zone of the shootdown (which may not even contain a base), or the region from which the offending X-Com craft originated (the latter is more likely on higher difficulties). Note that performing a [[UFO Ground Assault]] will never trigger Retaliation.
			*A "scheduled" Retaliation mission is a more general response to the ongoing threat posed by X-Com, and is assigned at the beginning of a new month like other [[Alien Missions]]. These will begin either when X-Com researches [[The Martian Solution]] or if the game goes on beyond a certain month (which month that is depends on difficulty), and occur once per month for the rest of the game in addition to the aliens' other activities. Scheduled Retaliation missions are performed by a random race (20% for each, regardless of month), and will always target the oldest X-Com base that doesn't already have a Retaliation mission looking for it.

	~~If you shoot down the retaliation scouts, the next scout~~ to appear in the patrol will be delayed by a random amount of time. However, the type of UFO may be upgraded to make it more difficult for you to shoot down. As alien mission have a set time frame for them to be completed, they will eventually abort the retaliation mission if the scouts are delayed long enough.		===Difficulty table===

	~~Note~~ that ~~assaulting an landed~~ Retaliation ~~scout when it is on the ground does not have this effect~~.		==Notes==
			*None of the UFOs performing Alien Retaliation will land. This can be diagnostic of Retaliation activity if X-Com lacks [[Hyper-Wave Decoder]]s, and also means that [[UFO Ground Assault]] is impossible; X-Com must shoot down Retaliation scouts in order to perform [[UFO Crash Recovery]].
	~~While the scouting parties do cause activity that will concern the Council, the aliens do not directly~~ [[~~Scoring#Alien_Scoring\|score~~]] for ~~destroying the base~~. ~~Beyond~~ the ~~material loss of the base~~, ~~assets~~ and ~~personnel~~, ~~you will only gain negative points~~ for ~~the soldiers or tanks killed defending~~ the base. ~~However, if you lose all bases to alien retaliation, X-COM will~~ be ~~wiped out and you lose the game~~.		*To distinguish between [[Battleship]]s that are merely acting as scouts for an Alien Retaliation, and those that are on an attack run, pay attention to their flight patterns. A Battleship on a scouting mission will arrive in the targetted zone at Very High altitude and top speed, and then slow down to much lower speeds to perform several passes at Very Low altitude. A Battleship on an attack run will '''immediately''' descend to Very Low altitude, and charge straight for the base at a full 5000 knots. This means that an attacking Battleship can '''only''' be shot down by an Avenger.
			*There is a design oversight in the code that monitors whether an X-Com base has been found and is due for an attacking [[Battleship]]. A flag in XBASES.DAT is set when a scouting UFO detects the base, which triggers a routine to spawn a Battleship on an attack run. The flag is removed when a [[Base Defence]] mission occurs - and '''only''' when that mission occurs. Shooting down the Battleship, or destroying it with [[Base Defence Systems]], will not remove the flag, causing another Battleship to attack a few days later. This will never end until a Battleship is allowed to invade the base.
	~~==Multiple Retaliations==~~

	~~Each time a retaliation mission~~ is ~~set up it will be run by~~ a ~~particular task force of aliens~~ that ~~are charged to find~~ an X-~~COM~~ base and ~~get troops inside to destroy it from within~~. ~~Once~~ a ~~team manages to drop a retaliation squad into your~~ base, ~~their mission will come~~ to an ~~end and they will cease their~~ attack.

	~~Each team works independently of the other,~~ and ~~do not share their findings with the others. So if they find a base,~~ only ~~they will know where it is.

Base locations are not retained once the~~ mission ~~has been completed~~. ~~It may indicate that~~ the ~~crew on the final battleship may be what is left of the task force and the base location either dies with them if they fail~~, or ~~is no longer required if they succeed.~~

	~~If you are targeted by more than one group at a time, you will need to crush them all to cease the attacks altogether. Once they have all been dealt~~ with~~, you will not have to worry about any further attacks until the next wave of retaliation scouts are encouraged to appear.~~

	== Base ~~Attack Loop==~~

	~~Due to a programming oversight~~, ~~destroying the battleship with base defences~~ will not ~~clear~~ the ~~retaliation mission~~ flag~~.
