I'm not quite sure what to make of a game with the title Killing Floor. Is it a psychotic floor gone bad, hellbent on the destruction of humanity? Perhaps a freak dance floor accident? I'm really not sure. Whatever the Killing Floor is, it's co-op, and co-op for six players at that.
Tripwire Interactive, makers of Red Orchestra, have announced that the website for Killing Floor has gone live and is loaded with details of this co-op shooter. We know the basic premise of the game, much like Left 4 Dead, is to survive waves of zombies. These zombies look a bit different though, for one, they appear to have lost their clothes. They also appear to carry chainsaws.
The new site has a bunch of screenshots and more information on the game, which is planned to be released on Steam sometime this year with full Steamworks support, that means achievements!
