It was a bit of a surprise to learn last month that yet another Unreal Tournament 2004 mod would be turned into a commerical stand alone product. Following in the footsteps of Red Orchestra and Damnation, the co-op shooter Killing Floor will soon be released via developer Tripwire Interactive via Steam.

The game's offiicial web site still doesn't have a lot about the title but it does have some new screenshots showing us something of what the final version will look like. The game itself has you and a bunch of friends (up two six players in full co-op mode) going up against zombies . . . er, creatures that have both melee and weapons attacks. There's still no word on a specific release date.
