XCom: Enemy Unknown

[hazard]

Chrysalids are actually slightly less scary in this version than they are in the first X-Com game. I mean, they will still tear your squad apart if you aren't careful, but they can't sprint in from out of nowhere and one shot your men anymore. Those zombies also don't spawn more chryssalids when they die if you hit them hard enough, which is rather easy when you start slinging around plasma weaponry.
