This game is the most brutal showcase of how an actual alien invasion would go. You don't heroicaly save everyone and you shouldn't. If you see a civilian on a terror mission with chrysalids you kill them to prevent more zombies and save your guys. Your guys can get mind controled leading to complete chaos when you try to evacuate from a clearly doomed mission. It doesn't ask you to save all your precious soldiers. It asks you to lead a global organization in a world close to colapse. Can you do it Commander?
Im a zoom zoom so at first i couldn't get into the game but now it hooked me. It's a masterpiece and one of the greatest games ever made.
