Injury and Fatigue (LWR)
Fatigue
AP Loss
While fatigued soldiers may still be deployed on missions, they may suffer a loss of APs (Action Points) at the beginning of each their turns. Click on the following to view the effects: Fatigue and Exhaustion
Accumulating Fatigue
Soldiers become fatigued after each mission. The fatigue will dissipate if the soldiers have time to rest before going on another mission. Fatigue duration scales with the number of turns that passed during the mission. SHIVs are not affected by fatigue.
The Second Wave option Consistent Fatigue (#35) disables fatigue increasing with the number of turns passed (and the 1% per turn reduction) and reverts to base fatigue value of 6 days.
Base Fatigue
Base Fatigue Time: +0.5 days of fatigue per turn on a mission

Fatigued Soldiers on Missions
Fatigued soldiers that go on missions will have their pre-mission fatigue added to their new fatigue they gained from the missions (only new fatigue is modified by Base Fatigue Modifiers).
Fatigued soldiers with over 30 days of fatigue (modified by campaign length) will have any additional fatigue converted into injury time.
Dealing with Fatigue
Ideally, you should have several teams of soldiers ready at any given point. This means that you can take most missions that the game will throw at you, which can sometimes be three in a row, especially with some abductions and if the Slingshot and Progeny DLCs are activated. Try to spread the experience around, and take advantage of easier missions to rank up low ranked soldiers. The last thing you want is for an important mission to come up and only have raw recruits ready to go.
Once you have researched Xenogenetics you can give your soldiers a Meld Injection which will reduce their fatigue and injury time by 80% for the cost of 200 meld.
SHIVs are excellent at minimizing fatigue spirals (all soldiers in the barracks with fatigue) as not only do they help bolster your roster but they also receive no fatigue, limiting the overall fatigue accumulation.
Injury
Any soldier that takes damage beyond their armor HP and into their base HP receives an injury. Even if this loss of HP is healed, the lowest point will count towards an injury.
As well, soldiers that take damage restricted to their armor HP may still become injured with a chance equal to twice the % of remaining HP lost. This will be denoted with a Injury popup. Certain perks and abilities can reduce this chance. Any injury taken with only armor HP will act as if the unit had been injured to 1 less than its max base HP.
Injuries will prevent a soldier from deploying in future battle until the injury is recovered from.
Accumulating Injuries
Base Injury
Base Injury time: 3 days + (Base HP% Lost x 30 days)
Example: a soldier with 5 base HP and 4 armor HP (9HP total) took 5 damage. This means he lost 1 base HP and all 4 armor HP. His base HP% lost would be 1 of his 5 base HP or 20%. His Base Injury time would then be: 1 + 20% * 30 days, or 7 days.
Base Injury Modifiers
| Ability | Base Injury Time |
|---|---|
| SHIVs | -50% |
| Advanced Repair | -25% (MECs and SHIVs only) |
| Advanced Surgery | -15% (MECs and soldiers only) |
| Advanced Bone Marrow | -30% |
| Will to Survive | -30% |
| Base HP higher than 6/10 (soldier/MEC) | -4% per Base HP |
| Base HP lower than 6/10 (soldier/MEC) | +4% per Base HP |
| Wolverine Blood (Second Wave option) | -50% |
| Difficulty (Normal/Classic/Brutal/Impossible) | -15%/-10%/-5%/0% |
| Campaign Length (MLW/NSLW/LW/VLW) | x4/x2/x1/x0.5 |
Fatigued Soldiers and Injuries
All fatigue time is converted to injury time when a soldier becomes injured
Dealing with Injuries
Like dealing with fatigue, you should have several teams of units ready at any given point. Injuries can be further reduced by mitigating damage you take. Sturdy units with Will to Survive, SHIVs, and MECs can all take more shots than most soldiers before dipping into their base HP and receiving an injury. Heavy armors and small armor items give more leeway for taking damage without becoming injured.
Injuries are reduced by simply letting time pass. Each in-game hour in the strategy game reduces injury time by an hour. Once all injuries are healed the unit's fatigue counter will begin (if they had any fatigue).
Another way to reduce injuries is once you have researched Xenogenetics you can give your units (including SHIVs) a Meld Injection. This will reduce their injury and fatigue time by 80% for the cost of 200 meld.
The Savior and First Aid perks both reduce the chance an armor HP injury occurs to anyone on the squad by 50%. Multiple instances of these perks can stack. As well, Will to Survive, Fortified, and Grit reduce the chance by 50%, but only on an individual level.
