If you need some more zombie-like shooting in your game diet, you will be getting a new course very soon. Developer Tripwire Interactive's previously announced multiplayer oriented shooter Killing Floor (based on a successful Unreal Tournament 2004 mod) now has an official release date of May 14 via Valve's Steam service.

Not only that but the game can now be pre-ordered via Steam for just $14.99, a 25 percent price cut from its normal price of $19.99. You can also check out the game's official web site which has relaunched this week with lots more info and screenshots from the game. We've added a number of those images to our Killing Floor screenshot gallery.
