A cooperative survival horror experience set in a variety of nightmarish and surreal settings. Band together with your team-mates to defeat increasingly overwhelming hordes of freakish enemies and eventually - a horrifying boss.
Definitely one of the better zombie FPS games I've played. If you like Nazi Zombies, you'll love this game. It's simple, stay alive and kill all of the zombies in the wave, then get to the trader to buy new guns/ammo for the next wave. The graphics are pretty good, not the best I've seen, but they are definitely better than a lot of games. The different types of zombies have unique characteristics and battle techniques that really make you think about which zombie you are fighting before you start shooting. So far, the only zombie games that I would choose to play above this one have been the Left 4 Dead and Dead Island series.
