Evac – XCOM 2
XCOM 2 puts players in the role of a Commander overseeing a battlefield with turn-based strategy combat. You’ll need to call the shots and make sure the mission is completed, whether you’re extracting a VIP, neutralizing enemies, or performing any number of objectives out there.
If you’re currently in a mission that has an evacuation point already set, all you need to do is stand there and hit the Evac action to evacuate. You can stand on the tip of the square, so don’t be wasting movement just to get into the center because if an alien is in Overwatch, they will shoot at you. Don’t worry if you can just barely reach it and have to use up two movement points, you can still Evac even if you’re out of movement.
For missions where there is no Evac point designated, you have to complete the mission to be extracted normally. If you happen to fail one of the objectives, though, and don’t have the firepower to take on the rest of the aliens, you can set up an Evac point yourself. Hit P on your keyboard and place the square wherever is best for all your remaining troops to reach it and get the hell out of there.
