Infiltration (LW2)

Turtledactyl: /* Enemy Strength */

{{Toc_(LW2)|40}}Infiltrating missions require you to dispatch a squad several days before the mission so they can study the target and make plans. This is represented by an in-game "infiltration" value which accumulates as the squad spends more time at the mission location. The speed at which a squad infiltrates depends on its size, equipment and abilities, as well as the stage of liberation the mission's region is in for some missions. The final infiltration value, at the time you launch the mission, affects several aspects of tactical gameplay. This includes the quantity of enemies, their detection radius, and the delay before the Skyranger arrives for evac. Mission rewards and objective timers are ''not'' affected by infiltration.

The infiltration mechanic is the method by which most, but not all, missions are launched. The system is designed to provide a balance between the assignment of your haven personnel on intel gathering, the number of troops and equipment you bring on the mission, and the danger you will encounter on the mission.

== Overview ==

When a mission is discovered you can deploy a squad, selecting soldiers and their loadout just like in the base game. Soldiers and equipment are unavailable while deployed to a mission. Once in place they will begin infiltrating. You can see their progress on the geoscape and you can click the mission bar to view details. From that screen you have the option to launch the mission immediately or to abort infiltration and recall your squad. The only penalty for aborting early is losing the squad's accumulated infiltration progress; you do not forfeit the mission. You can try to re-infiltrate with a newly selected squad if there is enough time left.

=== Infiltration Duration ===

Most infiltration missions have a limited duration. You must launch the mission before it expires, but you don't have to watch the clock: if you have a squad deployed to infiltrate then the game will prompt you to launch or abort just before the mission expires. The time remaining for a mission is shown in the geoscape and in the top left of mission load-out screen. The load-out screen also displays the time to infiltrate, updated as you add or remove soldiers and equipment. This is how long the squad needs to reach 100% infiltration and eliminate all tactical penalties. If the squad's infiltration time is greater than the mission's time remaining then you won't be able to fully infiltrate. You can still deploy, but the mission will be more difficult. Infiltration can also be greater than 100%, up to 200% if the squad is allowed to remain infiltrating, which will make the mission easier.

A mission's expiration timer starts when it is created; the mission is not visible at this time. The local haven must collect enough intel to reveal the mission. Assigning more resistance members to the "intel" job can make missions considerably easier by discovering missions earlier and allowing more time to infiltrate. Most infiltration missions have a base duration of 18 days, which is randomized by a few days each time a mission is created. For more information on generating missions, see the [[Missions (LW2)| Missions]] page.

== Infiltration Time ==

To calculate the time a squad will take to reach 100% infiltration, the game uses 4 factors: Base Infiltration Time, Squad Size Factor, Squad Covertness Factor, and Liberation Factor. Infiltration can also be boosted, and liberating a region while a squad is infiltrating a mission in it will heavily affect their infiltration.

=== Base Infiltration Time ===

The base time each mission needs to be infiltrated changes depending on difficulty. For most missions the base times are:

{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|96 hours (4 days) || 120 hours (5 days) || 144 hours (6 days) || 144 hours (6 days)
|}

However some Golden Path missions (Blacksite, Forge and Psi Gate) have double the base time of most missions. Other missions may have a flat modifier (positive or negative) depending on the activity, which is applied directly to the base time needed.

=== Squad Size Factor ===

The number of soldiers in a squad can affect significatively the hours needed for full infiltration:

{|class="wikitable" style="text-align: center"
|'''Squad Size''' || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9 || 10 || 11 || 12+
|-
|'''Size Factor''' || 0.7 || 0.725 || 0.75 || 0.8 || 1 || 1.25 || 1.5 || 1.8 || 2.8 || 4 || 5.2 || 6.4
|}

The GTS project "Tactical Infiltrations" will reduce the Size Factors for 6 and 7 soldiers by 0.125, and "Large Unit Infiltrations" will reduce the Size Factors for higher numbers:

{|class="wikitable" style="text-align: center"
|'''Squad Size''' || 8 || 9 || 10 || 11 || 12+
|-
|'''Reduction''' || -0.2 || -0.35 || -0.5 || -0.5 || -0.5
|}

The Squad Size Factor has a minimum of 0.05 and a maximum of 10. The hours to full infiltration will be modified by the Base Infiltration Time multiplied by the Squad Size Factor - 1. A Squad Size Factor under 1 will remove hours instead.

=== Squad Covertness ===

When a squad of soldiers has been chosen to infiltrate a mission, the game will calculate the average covertness of the squad in this way:
* For each soldier, calculate two values from their equipment (including weapon upgrades): Covertness Value and Covertness Weight.
** Covertness Value is calculated by adding each piece of equipment's Covertness Value multiplied by their Covertness Weight. Empty spots have no value.
** Covertness Weight is calculated by adding each piece of equipment's Covertness Weight. Empty spots have 0.2 weight.
* If the soldier has leadership bonuses from the squad's officer, items or abilities that reduce individual infiltration times, apply each multiplier to their Covertness Value ''multiplicatively''.
** [[Perk_List_(LW2)#Covert|Covert]] has a 0.97 multiplier.
** [[Perk_List_(LW2)#Ghostwalker|Ghostwalker]] has a 0.98 multiplier.
** [[Perk_List_(LW2)#Tradecraft|Tradecraft]] has a 0.8 multiplier.
** Leadership bonus multiplier starts at 1, reduced by 0.0075 for each successful mission under this officer, down to a minimum of 0.75 after 34 missions.
* To obtain each soldiers final covertness contribution: Covertness Value / Covertness Weight.
* For the squad's covertness, add all soldiers' final covertness, and ''for each of them'' that has an ability that reduces squad infiltration time (i.e. [[Perk_List_(LW2)#Infiltrator|Infiltrator]]), apply each multiplier to the squad's covertness ''multiplicatively''.
** [[Perk_List_(LW2)#Infiltrator|Infiltrator]] has a 0.85 multiplier.
* Divide the squad's total covertness by the number of soldiers to obtain the average covertness.

The Squad Covertness Factor starts as 1 at 100 average covertness, and for each 100 difference in average covertness, the Factor will be increased or reduced by 0.67 (for example, 0.33 at 0 average covertness and 1.67 at 200 average covertness.

The Squad Covertness Factor has a minimum of 0.05 and a maximum of 10. If the Squad Size Factor is higher than 1, the Squad Covertness Factor will be applied to the Base Infiltration Time plus the hours the Squad Size Factor adds; if not, it will be applied only to the Base Infiltration Time. The hours to full infiltration will be modified by this time multiplied by the Squad Covertness Factor - 1. A Squad Covertness Factor under 1 will remove hours instead.

=== Liberation Factor ===

For some missions (Alien Facility Sabotage, Blacksite, Forge and Psi Gate), the stage of liberation that the region where the mission takes place is in will also affect infiltration times. This factor will always reduce infiltration times:

{|class="wikitable" style="text-align: center"
|'''Liberation Stage''' || No progress || Found a lead (First Liberation mission unlocked) || Rescue a Defector Completed || Hinder ADVENT Operations Completed || Destroy Network Tower Completed || Region Liberated
|-
|'''Liberation Factor''' || 1 || 0.7 || 0.55 || 0.4 || 0.25 || 0.1
|}

The hours to full infiltration will be modified by the Base Infiltration Time multiplied by the Liberation Factor - 1.

=== Boosting Infiltration ===

Boosting spends 25 Intel (30 on Legend) to further apply a factor to the time to full infiltration depending on difficulty:

{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|2 || 1.75 || 1.5 || 1.5
|}

The time to full infiltration will be divided by this factor after infiltration is boosted. This change applies retroactively to the calculation of infiltration %.

=== Final Infiltration Time ===

Adding together every factor will result in the time to reach 100% infiltration with that particular squad:

<code>
Base Infiltration Time = Base Hours (depending on difficulty) * 2 (if the mission is Blacksite, Forge or Psi Gate) + Flat Hours Modifier (depends on mission)

Squad Size Time = Base Infiltration Time * (Squad Size Factor - 1)

Squad Covertness Time = (Base Infiltration Time + Squad Size Time (if positive)) * (Squad Covertness Factor - 1)

Liberation Time (if mission is Sabotage Alien Facility, Blacksite, Forge or Psi Gate) = Base Infiltration Time * (Liberation Factor - 1)

Hours to 100% Infiltration = (Base Infiltration Time + Squad Size Time + Squad Covertness Time + Liberation Time) / Boost Factor (if intel is spent)</code>

The hours to 100% infiltration cannot be lower than 12 or higher than 1296 (54 days). To calculate the infiltration value the squad has, divide the hours the squad has been infiltrating by the hours to 100% infiltration. The resulting percentage is the infiltration value shown on the mission screen, from 0% to 200%, which will have several effects on the tactical part of the mission.

If a region is liberated while squads are infiltrating missions in it, all infiltration values will be boosted by a flat 50% and the missions will be forced to begin immediately or be aborted.

== Effects of Infiltration ==
An infiltration value of 100% gives no bonuses or penalties. Lower infiltration aids the aliens and higher infiltration aids XCOM, but these effects are not equal: the penalties for a low infiltration level are much worse than the bonuses for an excessive infiltration.

=== Enemy Strength ===

Each breakpoint corresponds to an increase or decrease in the effective [[ADVENT's_Agenda_(LW2)#Strength_Level|Strength Level]] for the mission, respectively. This will directly change the number of enemies that spawn, which may affect the [[Missions (LW2)#Enemy Activity Level|Enemy Activity Level]] reported. Being between two breakpoints gives you a percent chance to upgrade to the next breakpoint and reduce the effective Strength Level accordingly, with the chance increasing proportionally as you approach the next breakpoint. The change in activity level is also vaguely indicated in the "Enemy Readiness" tag when looking at the mission.

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 9% || 17% || 25% || 34% || 42% || 50% || 59% || 67% || 75% || 84% || 92% || 100% || 125% || 150% || 200%
|-
| '''Strength Level Change''' || +12 || +11 || +10 || +9 || +8 || +7 || +6 || +5 || +4 || +3 || +2 || +1 || 0 || -1 || -2 || -3
|-
| '''Enemy Readiness'''
|colspan="3"| Impregnable
|colspan="3"| Fortified
|colspan="3"| Alerted
|colspan="3"| Guarded
| Normal
|colspan="3"| Vulnerable
|}

For example, consider a mission with baseline Strength Level 3. Above 92% infiltration you are guaranteed to receive at worst effective Strength Level 4, with an increasing chance to get Level 3 as you approach 100% infiltration.

There are many more breakpoints below 100% than there are above it; missions will quickly become significantly more difficult at under 100% and you should try your best to reach this percentage. Similarly the difference between 150% and 200% is very small and may not be worth the squad strength cuts needed to attain 200%.

Golden Path missions (Blacksite, Forge, Psi Gate, ADVENT Network Tower and Alien Fortress) are '''not''' affected by this modifier.

=== Skyranger Evac Delay ===

The Evac Delay timer can be modified by the infiltration value, among other things. As soon as the infiltration value indicated in the breakpoint is reached, the corresponding Evac Delay modifier will be active. For more information on Skyranger Evac time, see [[Mechanics (LW2)#Skyranger Evac Delay|Skyranger Evac Mechanics]].

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 30% || 60% || 100% || 150% || 200%
|-
| '''Evac Delay Turns''' || +3 || +2 || +1 || 0 || -1 || -2
|}

=== Enemy Reflex Actions ===

The chance of enemies taking a reflex action when they're activated on their turn can be modified by the infiltration value, depending on difficulty.
* Each point of infiltration over 100% will decrease the reflex chance by this amount:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|1% || 0.5% || 0.1% || 0.1%
|}
* Each point of infiltration under 100% will increase the reflex chance by this amount:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|0% || 0.1% || 0.5% || 1%
|}

=== Concealment Status ===

On Troop Column Ambushes, Supply Raids, or landed UFO missions, a minimum of 100% infiltration value is needed for the squad to start the mission in concealment.

=== Enemy Detection Range ===

The radius at which enemies can detect soldiers in concealment is affected by the infiltration value in different ways depending on difficulty.
* Above 100%, the detection radius of enemies will be reduced linearly from 100% of its default value to the minimum percentage at 200%:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|83.34% || 83.34% || 87.25% || 100%
|}
* Below 100%, the detection radius of enemies will be increased linearly from 100% of its default value to the maximum percentage at 0%:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|100% || 151% || 151% || 200%
|}

Disguised Faceless will not be affected by this. For more information on enemy detection, see [[Mechanics (LW2)#Detection Range|Detection Radius Mechanics]].

=== Enemy Reinforcements ===

Low infiltration values will advance the reinforcement queue from the start, meaning the first reinforcements spawned will be stronger. As soon as the infiltration value indicated in the breakpoint is reached, the corresponding reinforcement queue modifier will be active:

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 20% || 40% || 60% || 80% || 100%
|-
| '''Queue Spots Advanced''' || 5 || 4 || 3 || 2 || 1 || 0
|}

Infiltration (LW2)

Turtledactyl: /* Effects of Infiltration */

{{Toc_(LW2)|40}}Infiltrating missions require you to dispatch a squad several days before the mission so they can study the target and make plans. This is represented by an in-game "infiltration" value which accumulates as the squad spends more time at the mission location. The speed at which a squad infiltrates depends on its size, equipment and abilities, as well as the stage of liberation the mission's region is in for some missions. The final infiltration value, at the time you launch the mission, affects several aspects of tactical gameplay. This includes the quantity of enemies, their detection radius, and the delay before the Skyranger arrives for evac. Mission rewards and objective timers are ''not'' affected by infiltration.

The infiltration mechanic is the method by which most, but not all, missions are launched. The system is designed to provide a balance between the assignment of your haven personnel on intel gathering, the number of troops and equipment you bring on the mission, and the danger you will encounter on the mission.

== Overview ==

When a mission is discovered you can deploy a squad, selecting soldiers and their loadout just like in the base game. Soldiers and equipment are unavailable while deployed to a mission. Once in place they will begin infiltrating. You can see their progress on the geoscape and you can click the mission bar to view details. From that screen you have the option to launch the mission immediately or to abort infiltration and recall your squad. The only penalty for aborting early is losing the squad's accumulated infiltration progress; you do not forfeit the mission. You can try to re-infiltrate with a newly selected squad if there is enough time left.

=== Infiltration Duration ===

Most infiltration missions have a limited duration. You must launch the mission before it expires, but you don't have to watch the clock: if you have a squad deployed to infiltrate then the game will prompt you to launch or abort just before the mission expires. The time remaining for a mission is shown in the geoscape and in the top left of mission load-out screen. The load-out screen also displays the time to infiltrate, updated as you add or remove soldiers and equipment. This is how long the squad needs to reach 100% infiltration and eliminate all tactical penalties. If the squad's infiltration time is greater than the mission's time remaining then you won't be able to fully infiltrate. You can still deploy, but the mission will be more difficult. Infiltration can also be greater than 100%, up to 200% if the squad is allowed to remain infiltrating, which will make the mission easier.

A mission's expiration timer starts when it is created; the mission is not visible at this time. The local haven must collect enough intel to reveal the mission. Assigning more resistance members to the "intel" job can make missions considerably easier by discovering missions earlier and allowing more time to infiltrate. Most infiltration missions have a base duration of 18 days, which is randomized by a few days each time a mission is created. For more information on generating missions, see the [[Missions (LW2)| Missions]] page.

== Infiltration Time ==

To calculate the time a squad will take to reach 100% infiltration, the game uses 4 factors: Base Infiltration Time, Squad Size Factor, Squad Covertness Factor, and Liberation Factor. Infiltration can also be boosted, and liberating a region while a squad is infiltrating a mission in it will heavily affect their infiltration.

=== Base Infiltration Time ===

The base time each mission needs to be infiltrated changes depending on difficulty. For most missions the base times are:

{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|96 hours (4 days) || 120 hours (5 days) || 144 hours (6 days) || 144 hours (6 days)
|}

However some Golden Path missions (Blacksite, Forge and Psi Gate) have double the base time of most missions. Other missions may have a flat modifier (positive or negative) depending on the activity, which is applied directly to the base time needed.

=== Squad Size Factor ===

The number of soldiers in a squad can affect significatively the hours needed for full infiltration:

{|class="wikitable" style="text-align: center"
|'''Squad Size''' || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9 || 10 || 11 || 12+
|-
|'''Size Factor''' || 0.7 || 0.725 || 0.75 || 0.8 || 1 || 1.25 || 1.5 || 1.8 || 2.8 || 4 || 5.2 || 6.4
|}

The GTS project "Tactical Infiltrations" will reduce the Size Factors for 6 and 7 soldiers by 0.125, and "Large Unit Infiltrations" will reduce the Size Factors for higher numbers:

{|class="wikitable" style="text-align: center"
|'''Squad Size''' || 8 || 9 || 10 || 11 || 12+
|-
|'''Reduction''' || -0.2 || -0.35 || -0.5 || -0.5 || -0.5
|}

The Squad Size Factor has a minimum of 0.05 and a maximum of 10. The hours to full infiltration will be modified by the Base Infiltration Time multiplied by the Squad Size Factor - 1. A Squad Size Factor under 1 will remove hours instead.

=== Squad Covertness ===

When a squad of soldiers has been chosen to infiltrate a mission, the game will calculate the average covertness of the squad in this way:
* For each soldier, calculate two values from their equipment (including weapon upgrades): Covertness Value and Covertness Weight.
** Covertness Value is calculated by adding each piece of equipment's Covertness Value multiplied by their Covertness Weight. Empty spots have no value.
** Covertness Weight is calculated by adding each piece of equipment's Covertness Weight. Empty spots have 0.2 weight.
* If the soldier has leadership bonuses from the squad's officer, items or abilities that reduce individual infiltration times, apply each multiplier to their Covertness Value ''multiplicatively''.
** [[Perk_List_(LW2)#Covert|Covert]] has a 0.97 multiplier.
** [[Perk_List_(LW2)#Ghostwalker|Ghostwalker]] has a 0.98 multiplier.
** [[Perk_List_(LW2)#Tradecraft|Tradecraft]] has a 0.8 multiplier.
** Leadership bonus multiplier starts at 1, reduced by 0.0075 for each successful mission under this officer, down to a minimum of 0.75 after 34 missions.
* To obtain each soldiers final covertness contribution: Covertness Value / Covertness Weight.
* For the squad's covertness, add all soldiers' final covertness, and ''for each of them'' that has an ability that reduces squad infiltration time (i.e. [[Perk_List_(LW2)#Infiltrator|Infiltrator]]), apply each multiplier to the squad's covertness ''multiplicatively''.
** [[Perk_List_(LW2)#Infiltrator|Infiltrator]] has a 0.85 multiplier.
* Divide the squad's total covertness by the number of soldiers to obtain the average covertness.

The Squad Covertness Factor starts as 1 at 100 average covertness, and for each 100 difference in average covertness, the Factor will be increased or reduced by 0.67 (for example, 0.33 at 0 average covertness and 1.67 at 200 average covertness.

The Squad Covertness Factor has a minimum of 0.05 and a maximum of 10. If the Squad Size Factor is higher than 1, the Squad Covertness Factor will be applied to the Base Infiltration Time plus the hours the Squad Size Factor adds; if not, it will be applied only to the Base Infiltration Time. The hours to full infiltration will be modified by this time multiplied by the Squad Covertness Factor - 1. A Squad Covertness Factor under 1 will remove hours instead.

=== Liberation Factor ===

For some missions (Alien Facility Sabotage, Blacksite, Forge and Psi Gate), the stage of liberation that the region where the mission takes place is in will also affect infiltration times. This factor will always reduce infiltration times:

{|class="wikitable" style="text-align: center"
|'''Liberation Stage''' || No progress || Found a lead (First Liberation mission unlocked) || Rescue a Defector Completed || Hinder ADVENT Operations Completed || Destroy Network Tower Completed || Region Liberated
|-
|'''Liberation Factor''' || 1 || 0.7 || 0.55 || 0.4 || 0.25 || 0.1
|}

The hours to full infiltration will be modified by the Base Infiltration Time multiplied by the Liberation Factor - 1.

=== Boosting Infiltration ===

Boosting spends 25 Intel (30 on Legend) to further apply a factor to the time to full infiltration depending on difficulty:

{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|2 || 1.75 || 1.5 || 1.5
|}

The time to full infiltration will be divided by this factor after infiltration is boosted. This change applies retroactively to the calculation of infiltration %.

=== Final Infiltration Time ===

Adding together every factor will result in the time to reach 100% infiltration with that particular squad:

<code>
Base Infiltration Time = Base Hours (depending on difficulty) * 2 (if the mission is Blacksite, Forge or Psi Gate) + Flat Hours Modifier (depends on mission)

Squad Size Time = Base Infiltration Time * (Squad Size Factor - 1)

Squad Covertness Time = (Base Infiltration Time + Squad Size Time (if positive)) * (Squad Covertness Factor - 1)

Liberation Time (if mission is Sabotage Alien Facility, Blacksite, Forge or Psi Gate) = Base Infiltration Time * (Liberation Factor - 1)

Hours to 100% Infiltration = (Base Infiltration Time + Squad Size Time + Squad Covertness Time + Liberation Time) / Boost Factor (if intel is spent)</code>

The hours to 100% infiltration cannot be lower than 12 or higher than 1296 (54 days). To calculate the infiltration value the squad has, divide the hours the squad has been infiltrating by the hours to 100% infiltration. The resulting percentage is the infiltration value shown on the mission screen, from 0% to 200%, which will have several effects on the tactical part of the mission.

If a region is liberated while squads are infiltrating missions in it, all infiltration values will be boosted by a flat 50% and the missions will be forced to begin immediately or be aborted.

== Effects of Infiltration ==
An infiltration value of 100% gives no bonuses or penalties. Lower infiltration aids the aliens and higher infiltration aids XCOM, but these effects are not equal: the penalties for a low infiltration level are much worse than the bonuses for an excessive infiltration.

=== Enemy Strength ===

Each breakpoint corresponds to an increase or decrease in the effective [[ADVENT's_Agenda_(LW2)#Strength_Level|Strength Level]] for the mission, respectively. This will directly change the number of enemies that spawn, which may affect the [[Missions (LW2)#Enemy Activity Level|Enemy Activity Level]] reported. Being between two breakpoints gives you a percent chance to upgrade to the next breakpoint and reduce the effective Strength Level accordingly, with the chance increasing proportionally as you approach the next breakpoint. The change in activity level is also vaguely indicated in the "Enemy Readiness" tag when looking at the mission.

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 9% || 17% || 25% || 34% || 42% || 50% || 59% || 67% || 75% || 84% || 92% || 100% || 125% || 150% || 200%
|-
| '''Strength Level Change''' || +12 || +11 || +10 || +9 || +8 || +7 || +6 || +5 || +4 || +3 || +2 || +1 || 0 || -1 || -2 || -3
|-
| '''Enemy Readiness'''
|colspan="3"| Impregnable
|colspan="3"| Fortified
|colspan="3"| Alerted
|colspan="3"| Guarded
| Normal
|colspan="3"| Vulnerable
|}

For example, consider a mission with baseline Strength Level 3. Above 92% infiltration you are guaranteed to receive at worst effective Strength Level 4, with an increasing chance to get Level 3 as you approach 100% infiltration. Note that this will not necessarily change the Enemy Activity Level display if the difference stays within one Activity Level band, but the number of enemy units has been reduced.

There are many more breakpoints below 100% than there are above it; missions will quickly become significantly more difficult at under 100% and you should try your best to reach this percentage. Similarly the difference between 150% and 200% is very small and may not be worth the squad strength cuts needed to attain 200%.

Golden Path missions (Blacksite, Forge, Psi Gate, ADVENT Network Tower and Alien Fortress) are '''not''' affected by this modifier.

=== Skyranger Evac Delay ===

The Evac Delay timer can be modified by the infiltration value, among other things. As soon as the infiltration value indicated in the breakpoint is reached, the corresponding Evac Delay modifier will be active. For more information on Skyranger Evac time, see [[Mechanics (LW2)#Skyranger Evac Delay|Skyranger Evac Mechanics]].

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 30% || 60% || 100% || 150% || 200%
|-
| '''Evac Delay Turns''' || +3 || +2 || +1 || 0 || -1 || -2
|}

=== Enemy Reflex Actions ===

The chance of enemies taking a reflex action when they're activated on their turn can be modified by the infiltration value, depending on difficulty.
* Each point of infiltration over 100% will decrease the reflex chance by this amount:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|1% || 0.5% || 0.1% || 0.1%
|}
* Each point of infiltration under 100% will increase the reflex chance by this amount:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|0% || 0.1% || 0.5% || 1%
|}

=== Concealment Status ===

On Troop Column Ambushes, Supply Raids, or landed UFO missions, a minimum of 100% infiltration value is needed for the squad to start the mission in concealment.

=== Enemy Detection Range ===

The radius at which enemies can detect soldiers in concealment is affected by the infiltration value in different ways depending on difficulty.
* Above 100%, the detection radius of enemies will be reduced linearly from 100% of its default value to the minimum percentage at 200%:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|83.34% || 83.34% || 87.25% || 100%
|}
* Below 100%, the detection radius of enemies will be increased linearly from 100% of its default value to the maximum percentage at 0%:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|100% || 151% || 151% || 200%
|}

Disguised Faceless will not be affected by this. For more information on enemy detection, see [[Mechanics (LW2)#Detection Range|Detection Radius Mechanics]].

=== Enemy Reinforcements ===

Low infiltration values will advance the reinforcement queue from the start, meaning the first reinforcements spawned will be stronger. As soon as the infiltration value indicated in the breakpoint is reached, the corresponding reinforcement queue modifier will be active:

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 20% || 40% || 60% || 80% || 100%
|-
| '''Queue Spots Advanced''' || 5 || 4 || 3 || 2 || 1 || 0
|}

Infiltration (LW2)

2023-10-25T23:31:18Z

Turtledactyl: /* Enemy Strength */ see Talk:Missions_(LWOTC)#Enemy Activity

{{Toc_(LW2)|40}}Infiltrating missions require you to dispatch a squad several days before the mission so they can study the target and make plans. This is represented by an in-game "infiltration" value which accumulates as the squad spends more time at the mission location. The speed at which a squad infiltrates depends on its size, equipment and abilities, as well as the stage of liberation the mission's region is in for some missions. The final infiltration value, at the time you launch the mission, affects several aspects of tactical gameplay. This includes the quantity of enemies, their detection radius, and the delay before the Skyranger arrives for evac. Mission rewards and objective timers are ''not'' affected by infiltration.

The infiltration mechanic is the method by which most, but not all, missions are launched. The system is designed to provide a balance between the assignment of your haven personnel on intel gathering, the number of troops and equipment you bring on the mission, and the danger you will encounter on the mission.

== Overview ==

When a mission is discovered you can deploy a squad, selecting soldiers and their loadout just like in the base game. Soldiers and equipment are unavailable while deployed to a mission. Once in place they will begin infiltrating. You can see their progress on the geoscape and you can click the mission bar to view details. From that screen you have the option to launch the mission immediately or to abort infiltration and recall your squad. The only penalty for aborting early is losing the squad's accumulated infiltration progress; you do not forfeit the mission. You can try to re-infiltrate with a newly selected squad if there is enough time left.

=== Infiltration Duration ===

Most infiltration missions have a limited duration. You must launch the mission before it expires, but you don't have to watch the clock: if you have a squad deployed to infiltrate then the game will prompt you to launch or abort just before the mission expires. The time remaining for a mission is shown in the geoscape and in the top left of mission load-out screen. The load-out screen also displays the time to infiltrate, updated as you add or remove soldiers and equipment. This is how long the squad needs to reach 100% infiltration and eliminate all tactical penalties. If the squad's infiltration time is greater than the mission's time remaining then you won't be able to fully infiltrate. You can still deploy, but the mission will be more difficult. Infiltration can also be greater than 100%, up to 200% if the squad is allowed to remain infiltrating, which will make the mission easier.

A mission's expiration timer starts when it is created; the mission is not visible at this time. The local haven must collect enough intel to reveal the mission. Assigning more resistance members to the "intel" job can make missions considerably easier by discovering missions earlier and allowing more time to infiltrate. Most infiltration missions have a base duration of 18 days, which is randomized by a few days each time a mission is created. For more information on generating missions, see the [[Missions (LW2)| Missions]] page.

== Infiltration Time ==

To calculate the time a squad will take to reach 100% infiltration, the game uses 4 factors: Base Infiltration Time, Squad Size Factor, Squad Covertness Factor, and Liberation Factor. Infiltration can also be boosted, and liberating a region while a squad is infiltrating a mission in it will heavily affect their infiltration.

=== Base Infiltration Time ===

The base time each mission needs to be infiltrated changes depending on difficulty. For most missions the base times are:

{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|96 hours (4 days) || 120 hours (5 days) || 144 hours (6 days) || 144 hours (6 days)
|}

However some Golden Path missions (Blacksite, Forge and Psi Gate) have double the base time of most missions. Other missions may have a flat modifier (positive or negative) depending on the activity, which is applied directly to the base time needed.

=== Squad Size Factor ===

The number of soldiers in a squad can affect significatively the hours needed for full infiltration:

{|class="wikitable" style="text-align: center"
|'''Squad Size''' || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9 || 10 || 11 || 12+
|-
|'''Size Factor''' || 0.7 || 0.725 || 0.75 || 0.8 || 1 || 1.25 || 1.5 || 1.8 || 2.8 || 4 || 5.2 || 6.4
|}

The GTS project "Tactical Infiltrations" will reduce the Size Factors for 6 and 7 soldiers by 0.125, and "Large Unit Infiltrations" will reduce the Size Factors for higher numbers:

{|class="wikitable" style="text-align: center"
|'''Squad Size''' || 8 || 9 || 10 || 11 || 12+
|-
|'''Reduction''' || -0.2 || -0.35 || -0.5 || -0.5 || -0.5
|}

The Squad Size Factor has a minimum of 0.05 and a maximum of 10. The hours to full infiltration will be modified by the Base Infiltration Time multiplied by the Squad Size Factor - 1. A Squad Size Factor under 1 will remove hours instead.

=== Squad Covertness ===

When a squad of soldiers has been chosen to infiltrate a mission, the game will calculate the average covertness of the squad in this way:
* For each soldier, calculate two values from their equipment (including weapon upgrades): Covertness Value and Covertness Weight.
** Covertness Value is calculated by adding each piece of equipment's Covertness Value multiplied by their Covertness Weight. Empty spots have no value.
** Covertness Weight is calculated by adding each piece of equipment's Covertness Weight. Empty spots have 0.2 weight.
* If the soldier has leadership bonuses from the squad's officer, items or abilities that reduce individual infiltration times, apply each multiplier to their Covertness Value ''multiplicatively''.
** [[Perk_List_(LW2)#Covert|Covert]] has a 0.97 multiplier.
** [[Perk_List_(LW2)#Ghostwalker|Ghostwalker]] has a 0.98 multiplier.
** [[Perk_List_(LW2)#Tradecraft|Tradecraft]] has a 0.8 multiplier.
** Leadership bonus multiplier starts at 1, reduced by 0.0075 for each successful mission under this officer, down to a minimum of 0.75 after 34 missions.
* To obtain each soldiers final covertness contribution: Covertness Value / Covertness Weight.
* For the squad's covertness, add all soldiers' final covertness, and ''for each of them'' that has an ability that reduces squad infiltration time (i.e. [[Perk_List_(LW2)#Infiltrator|Infiltrator]]), apply each multiplier to the squad's covertness ''multiplicatively''.
** [[Perk_List_(LW2)#Infiltrator|Infiltrator]] has a 0.85 multiplier.
* Divide the squad's total covertness by the number of soldiers to obtain the average covertness.

The Squad Covertness Factor starts as 1 at 100 average covertness, and for each 100 difference in average covertness, the Factor will be increased or reduced by 0.67 (for example, 0.33 at 0 average covertness and 1.67 at 200 average covertness.

The Squad Covertness Factor has a minimum of 0.05 and a maximum of 10. If the Squad Size Factor is higher than 1, the Squad Covertness Factor will be applied to the Base Infiltration Time plus the hours the Squad Size Factor adds; if not, it will be applied only to the Base Infiltration Time. The hours to full infiltration will be modified by this time multiplied by the Squad Covertness Factor - 1. A Squad Covertness Factor under 1 will remove hours instead.

=== Liberation Factor ===

For some missions (Alien Facility Sabotage, Blacksite, Forge and Psi Gate), the stage of liberation that the region where the mission takes place is in will also affect infiltration times. This factor will always reduce infiltration times:

{|class="wikitable" style="text-align: center"
|'''Liberation Stage''' || No progress || Found a lead (First Liberation mission unlocked) || Rescue a Defector Completed || Hinder ADVENT Operations Completed || Destroy Network Tower Completed || Region Liberated
|-
|'''Liberation Factor''' || 1 || 0.7 || 0.55 || 0.4 || 0.25 || 0.1
|}

The hours to full infiltration will be modified by the Base Infiltration Time multiplied by the Liberation Factor - 1.

=== Boosting Infiltration ===

Boosting spends 25 Intel (30 on Legend) to further apply a factor to the time to full infiltration depending on difficulty:

{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|2 || 1.75 || 1.5 || 1.5
|}

The time to full infiltration will be divided by this factor after infiltration is boosted. This change applies retroactively to the calculation of infiltration %.

=== Final Infiltration Time ===

Adding together every factor will result in the time to reach 100% infiltration with that particular squad:

<code>
Base Infiltration Time = Base Hours (depending on difficulty) * 2 (if the mission is Blacksite, Forge or Psi Gate) + Flat Hours Modifier (depends on mission)

Squad Size Time = Base Infiltration Time * (Squad Size Factor - 1)

Squad Covertness Time = (Base Infiltration Time + Squad Size Time (if positive)) * (Squad Covertness Factor - 1)

Liberation Time (if mission is Sabotage Alien Facility, Blacksite, Forge or Psi Gate) = Base Infiltration Time * (Liberation Factor - 1)

Hours to 100% Infiltration = (Base Infiltration Time + Squad Size Time + Squad Covertness Time + Liberation Time) / Boost Factor (if intel is spent)</code>

The hours to 100% infiltration cannot be lower than 12 or higher than 1296 (54 days). To calculate the infiltration value the squad has, divide the hours the squad has been infiltrating by the hours to 100% infiltration. The resulting percentage is the infiltration value shown on the mission screen, from 0% to 200%, which will have several effects on the tactical part of the mission.

If a region is liberated while squads are infiltrating missions in it, all infiltration values will be boosted by a flat 50% and the missions will be forced to begin immediately or be aborted.

== Effects of Infiltration ==
An infiltration value of 100% gives no bonuses or penalties. Lower infiltration aids the aliens and higher infiltration aids XCOM, but these effects are not equal: the penalties for a low infiltration level are much worse than the bonuses for an excessive infiltration.

=== Enemy Strength ===

Each breakpoint corresponds to an increase or decrease in the effective [[ADVENT's_Agenda_(LW2)#Strength_Level|Strength Level]] for the mission, respectively. This will directly change the number of enemies that spawn, which may affect the [[Missions (LW2)#Enemy Activity Level|Enemy Activity Level]] reported. Being between two breakpoints gives you a percent chance to upgrade to the next breakpoint and reduce the effective Strength Level accordingly, with the chance increasing proportionally as you approach the next breakpoint. The change in activity level is also vaguely indicated in the "Enemy Readiness" tag when looking at the mission.

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 9% || 17% || 25% || 34% || 42% || 50% || 59% || 67% || 75% || 84% || 92% || 100% || 125% || 150% || 200%
|-
| '''Strength Level Change''' || +12 || +11 || +10 || +9 || +8 || +7 || +6 || +5 || +4 || +3 || +2 || +1 || 0 || -1 || -2 || -3
|-
| '''Enemy Readiness'''
|colspan="3"| Impregnable
|colspan="3"| Fortified
|colspan="3"| Alerted
|colspan="3"| Guarded
| Normal
|colspan="3"| Vulnerable
|}

For example, consider a mission with baseline Strength Level 3. Above 92% infiltration you are guaranteed to receive at worst effective Strength Level 4, with an increasing chance to get Level 3 as you approach 100% infiltration. Note that this will not necessarily change the Enemy Activity Level display if the difference stays within one Activity Level band; but if you have the Shadow Chamber you will see that the number of enemy units has been reduced.

There are many more breakpoints below 100% than there are above it; missions will quickly become significantly more difficult at under 100% and you should try your best to reach this percentage. Similarly the difference between 150% and 200% is very small and may not be worth the squad strength cuts needed to attain 200%.

Golden Path missions (Blacksite, Forge, Psi Gate, ADVENT Network Tower and Alien Fortress) are '''not''' affected by this modifier.

=== Skyranger Evac Delay ===

The Evac Delay timer can be modified by the infiltration value, among other things. As soon as the infiltration value indicated in the breakpoint is reached, the corresponding Evac Delay modifier will be active. For more information on Skyranger Evac time, see [[Mechanics (LW2)#Skyranger Evac Delay|Skyranger Evac Mechanics]].

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 30% || 60% || 100% || 150% || 200%
|-
| '''Evac Delay Turns''' || +3 || +2 || +1 || 0 || -1 || -2
|}

=== Enemy Reflex Actions ===

The chance of enemies taking a reflex action when they're activated on their turn can be modified by the infiltration value, depending on difficulty.
* Each point of infiltration over 100% will decrease the reflex chance by this amount:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|1% || 0.5% || 0.1% || 0.1%
|}
* Each point of infiltration under 100% will increase the reflex chance by this amount:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|0% || 0.1% || 0.5% || 1%
|}

=== Concealment Status ===

On Troop Column Ambushes, Supply Raids, or landed UFO missions, a minimum of 100% infiltration value is needed for the squad to start the mission in concealment.

=== Enemy Detection Range ===

The radius at which enemies can detect soldiers in concealment is affected by the infiltration value in different ways depending on difficulty.
* Above 100%, the detection radius of enemies will be reduced linearly from 100% of its default value to the minimum percentage at 200%:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|83.34% || 83.34% || 87.25% || 100%
|}
* Below 100%, the detection radius of enemies will be increased linearly from 100% of its default value to the maximum percentage at 0%:
{|class="wikitable" style="text-align: center"
!Rookie !! Veteran !! Commander !! Legend
|-
|100% || 151% || 151% || 200%
|}

Disguised Faceless will not be affected by this. For more information on enemy detection, see [[Mechanics (LW2)#Detection Range|Detection Radius Mechanics]].

=== Enemy Reinforcements ===

Low infiltration values will advance the reinforcement queue from the start, meaning the first reinforcements spawned will be stronger. As soon as the infiltration value indicated in the breakpoint is reached, the corresponding reinforcement queue modifier will be active:

{|class="wikitable" style="text-align: center"
| '''Infiltration Value''' || 0% || 20% || 40% || 60% || 80% || 100%
|-
| '''Queue Spots Advanced''' || 5 || 4 || 3 || 2 || 1 || 0
|}

{{Toc_(LWOTC)|40}}

== Overview ==

=== Enemy Activity ===

Enemy Activity refers to the quantity of enemies deployed on a map. Enemy Activity Level is an estimation of the number of enemy units you will encounter at 100% infiltration; the '''actual''' number of enemy units depends on your infiltration rate (for more information, see the [[Infiltration (LW2)|Infiltration]] page). In general, at 0% infiltration, the number will be several steps higher than the baseline; at 200% infiltration, it will be a few steps lower. These steps are dependent on mission type and do not necessarily correspond to one Enemy Activity Level per step.

'''Notes'''
* Mission Timer
**This value is increased by + 4 in Rookie difficulty and by +2 in Veteran
**Objective timers only affect the primary objective. Failing to complete the objective before the timer expires will result in failing the mission but you can still evac your soldiers.
**Evac timers put an absolute limit on mission duration. Any soldier still on the map when the timer reaches 0 is lost (captured). When the timer reaches 1, the last turn start (there is no "0 turns left" turn).
**Reinforcement timers are delays before increasingly strong reinforcements start dropping. You can still complete a mission after such a timer reaches zero but it will become harder with each wave. This timer starts only after you break concealment.
**Several non timed missions (such as the Blacksite and Network Tower) include a hidden reinforcement timer.
* Infiltration
** Yes - the squad can infiltrate the site to reduce enemy strength
** 100% - infiltration needs to reach at least this value before mission can be launched
** No - squad goes directly into combat, skipping infiltration
** Alerted - mission starts immediately, no squad concealment, enemies start on yellow alert
* Evacuation
** Evac Flare - squad can call the Skyranger to be able to evacuate the mission
** Fixed Exit - squad has to reach exit area
** Countdown Exit - squad has to wait until exit area becomes active
* Loot - if yes, alien corpses and material will be recovered if the battle is won; if no, only actual 'item' loot (such as datapads) is recovered

== Generating Missions ==

Missions spawn automatically as the days pass, and expire after a given window of time. The mission is not visible at this time; the local haven must collect enough intel to reveal the mission. Assigning more resistance members to the "intel" job can make missions considerably easier by discovering missions earlier and allowing more time to infiltrate. A mission's expiration timer starts when it is created, not when it is discovered; most infiltration missions have a base duration of 18 days, which is randomized by a few days each time a mission is created.

Havens each generate "intel points" from having personnel assigned to intel gathering. These points are applied to undiscovered missions in the region at certain update intervals, currently 4 times a day (every 6 hours). Each mission keeps a pool of collected intel points. The difficulty of discovering a certain type of mission is controlled by two numbers: "required intel" and "discovery chance". A mission cannot be detected until you generate intel equal to the "required intel" value. Once the minimum is reached there is a random chance (1/4 of discovery chance) to discover the mission at every update. The probability is based on the mission's "percent chance" stat, multiplied by the number of intel points collected past the required minimum.

In the table below, a basic level-0 resistance member is defined as one "intel point" per day. A level-1 resistance member is worth 1.5 points, a level-2 is worth 2, and the Avenger scanning is worth 4. A scientist assigned as haven liaison adds an extra 20% bonus to the entire haven. Each faceless reduces overall intel point generation by 3/5/6/7% depending on difficulty (regardless of what job the faceless is doing).

'''Example:''' A haven with six level-0 resistance members and one level-1 assigned to intel, plus a scientist liaison, generates 9 "points" per day. The first mission in the liberation chain spawns. The haven can't detect this mission until it generates 22 points, which takes just under 2.5 days.

One day after that, the haven has an 4.5% chance to detect the mission: it has 9 intel points in the pool (subtracting out the 22 needed for the required intel) times 2 per point, resulting in 18 discovery chance which means you'll have 4.5% chance to detect the mission every 6 hours. One day later, the haven has 18 points and has a 36 discovery chance (9% to detect every 6 hours).

== Types of Missions ==

The type of mission affects a variety of factors: what the primary objective is, what type of rewards will be received, how long the squad has to complete the objective, how strong of a force the enemy will tend to field relative to other missions in the region, whether the squad starts concealed or not, and even where the squad can extract from.

Perhaps the most important factor is whether or not a squad needs to infiltrate or not, and how long the squad has to do it. For more information on infiltration mechanics, see the [[Infiltration (LW2) | Infiltration]] page for details.

=== Guerrilla Operations ===

These missions will generate regularly regardless of ADVENT activity in a region. XCOM will infiltrate some city and complete some useful objective, typically acquiring personnel and/or intel in the process.

* Jailbreak – XCOM must infiltrate an ADVENT jail and rescue 2-4 prisoners. Success will add them to the region's Haven. At least one must be saved for the mission to be a success (any others are optional/extra). ''Concealed Start''.
** Prisoners can be new soldiers if the region already has a large number of rebels.

* Rescue VIP - Two variants;
** XCOM must lead a VIP (a soldier, scientist, or engineer) to the extraction point. ''No concealment''.
** XCOM must secure a vehicle containing the VIP, free them, then lead them to the extraction point. ''Concealed Start''

* Hack a Workstation - XCOM must hack a particular workstation. Awards intel upon completion. ''Concealed Start''.



=== Retaliation Missions ===

Retaliation missions trigger with increasing frequency and severity as XCOM takes action in a particular region and draws attention towards it. Retaliation missions have no infiltration timer. The Haven Advisor of a region, if a soldier, will typically be present at these missions, alongside various resistance personnel outfitted with the basic weapons and equipment that rookie XCOM personnel deploy with.

* Rendezvous: When XCOM rescues or recruits resistance members, there is a chance that they may be Faceless; when Faceless disguised as members of the Resistance is detected as they go to meet with their ADVENT handlers, Resistance personnel from the local haven will deploy to the scene and hunt them down. You will not be able to arm or equip a squad to this mission. XCOM must detect Faceless by stationing a soldier as the Haven advisor. ''Concealed Start''.

* Supply Convoy: XCOM must deploy a squad to defend a supply convoy and its Resistance personnel from ADVENT attacks. ''No concealment''.

* Intel Raid: ADVENT attacks a Resistance listening post and XCOM must deploy a squad to defend its equipment and Resistance personnel. ''No concealment''.

* Recruitment Raid: ADVENT forces attack Resistance recruiters within a region. XCOM must deploy a squad and extract those Resistance members. ''No concealment''.

* Full Retaliation: XCOM must defend the Haven and it's Resistance members against an onslaught of ADVENT forces until the Skyranger can get into position for extraction. This mission usually comes in two parts.
** '''Retaliation 1''': This will be a destroy the relay mission but the briefing will state that Advent is searching for the haven and that you need to prevent a '''DATA LEAK'''. Completing this mission keeps the haven safe. (If you don't detect this mission, you go straight to a full retaliation.)
** '''Full retaliation (Retaliation 2)''': XCom must defend the Haven. This mission comes in two different flavours:
:# Many ADVENT in the AO trying to kill members of your resistance haven. You must rush to kill them to save resistance members. This mission will not yield corpses.
:# ADVENT drops unlimited reinforcements and you must rally all resistance members and soldiers to the EVAC zone to save them. This mission will also not yield corpses.

* Region Invasion: ADVENT attempts to retake a liberated region by assaulting a city center. XCOM must destroy a psionic relay that summons continuous reinforcements, then eliminate any remaining forces. ''No concealment''.

=== Liberation Missions ===

As part of its attempts to liberate a region from ADVENT control, XCOM will conduct a set sequence of five operations. The early missions are difficult to detect and the later missions receive an substantial bonus to activity level, over and above the strength value of the region. The liberation missions 1 to 3 are clearly marked with the word "Liberation" (which was not the case in LW2).

* '''Liberation 1:''' Hacking Guerrilla Op. ''Concealed Start''.
* '''Liberation 2:''' Rescue Defector. XCOM must rescue a VIP from a city location and move to the extraction point. ''Not Concealed''.
* '''Liberation 3:''' There are at least 2 possible mission types. Either mission type you get will have "Liberation" as part of the objective. Now do take note, Lib3 will also have an Advent strength bonus (above the regional base) meaning the baseline activity will be a decent amount higher as well as the tech you'll be facing. So go in nice and prepared for this one.
**Dark VIP mission (which seems to be more common) - There is also a high probability that the civilians on the map are Faceless
**Destroy the Relay mission.
* '''Liberation 4''' - Regional Network Tower Liberation: XCOM must deploy to and liberate an advent network tower. This will not expire once unlocked, and is quite difficult. A small squad (up to five soldiers) must hack a console at the far end of the map. Doing so disables the reinforcement timer and stuns all remaining enemies. The mission ends only when there are no remaining enemies, and reinforcements will come rapidly once the alarm is raised. ''Concealed Start''.
* '''Liberation 5''' - ADVENT Facility Assault: XCOM must deploy to and overtake a well-defended ADVENT facility. This will not expire once unlocked, and is quite difficult. ''Concealed Start''.

Note that failing or skipping a liberation mission does not reset the path. You'll just have to detect it again (unless it's the tower or base, which are persistent once you unlock them).

=== UFO Hunt ===

Advent may launch a dark event that sends a UFO to hunt the avenger. After 6-14 days, the UFO intercepts the avenger in which there is a 50% chance to avoid them. If successful, an avenger defense launches requiring XCOM to defend itself and destroy the spike emitting EMP preventing the avenger from escaping. The mission must be completed in order for XCOM to escape and continue the fight or all is lost. Once a campaign has experienced at least one avenger defense mission, any future UFO hunts have a 0/25/35/50% (based on difficulty) chance to intercept the avenger.

A UFO may also be launched once XCOM completes a story mission objective (blacksite/forge/psi gate) with a 25/75/100% chance respectively and this can only occur once meaning that, for example, if the blacksite has triggered a hunt, then completing the psi gate will not trigger another. These UFOs are guaranteed to intercept the avenger unless one has already occured in which it uses the interception chances after the first listed above.

== Collecting Enemy Corpses ==
Long War 2 uses the correct term for military equipment and supplies: [https://en.wikipedia.org/wiki/Materiel materiel].

Most missions in Long War 2 require you to evacuate and you do not keep the bodies of fallen Advent or Aliens. As corpses are much more valuable in Long War 2 players should make special consideration for missions which do allow them to keep the corpses of fallen foes.

The following mission types allow collection of enemy materiel:
* Ambush troop column: These missions are the only way to actively reduce ADVENT strength in a region.
* Supply convoy ambush: Alloys you to destroy ADVENT troops about to reinforce a region, this prevents ADVENT strength from increasing.
* Invasion
* Rendezvous
* Regional HQ assault

It should be noted that while Smash N Grab missions list Enemy Material as their reward, they no longer allow the collection of corpses from the battlefield. Unlike the five missions listed above, material recovered from Smash N Grabs is not dependent on the state of the battlefield, only on the number of Advent Resource Caches successfully retrieved. The Resource Caches can provide alloys, elerium, elerium cores, or supplies, but not corpses.

===Strategy===
As Vahlen has taught us, explosives destroy all recoverable materiel when delivering the killing blow as both a possible loot drop and the corpse will be destroyed. Flamethrowers also destroy corpses if the initial hit kills the target, though burning damage will leave a collectible corpse and drop timed loot if carried. Consider using the Needle Grenades perk for grenadiers if you are in need of explosives use.

It may be beneficial to sabotage your infiltration percentage to increase the enemy presence if you feel you will be victorious. You are allowed to start any infiltration mission early from the geoscape. Note that enemy readiness will also be boosted if you begin prematurely, increasing their detection range, evac delay, and reinforcements strength. For supply convoys and troop columns, enemies also gain a flat aim and defense bonus with their HP multiplied based on infiltration in intervals of 25% (0-24/25-49/50-74/75-99). Although there is great reward in acquiring plenty of corpses, it is important to be wary of the great risks involved that may be more harmful than its worth.

Turtledactyl: Created page with "== Enemy Activity == The '''Enemy Activity Level''' section & table currently imply that during infiltration, the number of enemy units goes down in Enemy Activity Level step..."

== Enemy Activity ==

The '''Enemy Activity Level''' section & table currently imply that during infiltration, the number of enemy units goes down in Enemy Activity Level steps; e.g. from 13-15 at 100% to 10-12 at 125% to 7-9 at 150%. This is a misapprehension.

The quantity of enemy units is derived from the Alert Level and mission schedule, which are not exposed to the player directly. The Alert Level is reduced/increased as expected at breakpoints of 125% etc. Crucially, when the game then calculates the quantity of enemy units from the Alert Level, ''this calculation depends on the particular mission schedule — not on the Enemy Activity Level table.'' The mission schedules can be found in XComSchedules.ini.

Let's look at a revealed guerilla ops mission of baseline Alert Level 4 as an example. If a player infiltrates this mission from 100% to 125% and expects to go down one Enemy Activity Level, he will be disappointed! From Alert Level 4 to Alert Level 3 we have reduced the actual number of enemy units from 12 to 10-11. The displayed Enemy Activity Level remains unchanged at 10-12 — Very Light.

! Infiltration !! Alert Level !! Enemy Units
|-
| 100% || 4 || 12
|-
| 125% || 3 || 10-11
|-
| 150% || 2 || 9
|}

Another issue is that some missions never go down to Extremely Light (7-9) at any level of infiltration; e.g. Secure UFO missions have a minimum of 14 enemy units at Alert Level 1.

The key here is that Enemy Activity Level is simply a way of giving the player a rough estimate of the number of enemy units before a Shadow Chamber is built; it is '''not''' a set of potential mission states. Those mission states are found in the schedules. '''The number of enemy units does not go up or down in Enemy Activity Level steps.''' I know, it's confusing.

I have edited the section to reflect this, and removed the table of Enemy Activity Level steps. The table helps to imply that these are the steps actually used, and it is not needed anyway because the numerical value is always displayed to the player whenever the Enemy Activity Level is on-screen.--[[User:Turtledactyl|Turtledactyl]] ([[User talk:Turtledactyl|talk]]) 01:13, 26 October 2023 (CEST)
