Creatures came out of what seemed to be thin air. Animated and alive. They came without a warning and swept the world ...

Great mod.Has ironsights, badass soundtrack that gets you in the mood in killing every enemy on sight, good voice acting and detailed maps, and obviously, custom weapons and enemies.This has good level of challenge too, you got combat, a bit of puzzle, and just a bit of scary parts.Recommend this to everyone.
