Killing Floors: Series

It’s a co-op survival horror game. Up to 6 players in online co-op mode, or just you, on your own, playing the Solo mode. The aim – cleanse each area of zombies, in waves, until you get to the last one. The Big One. The Patriarch. Then exterminate him, too. Actually, they aren’t “zombies”. They are the left-over “specimens” from a cheap and dirty government program to clone soldier-monsters.
