Killing Floor, once a UT2k4 mod, will be released on May 14th by Tripwire Interactive, the folks who brought you Red Orchestra (also started as an Unreal mod). Pre-purchase and save $5.
Here's a short description:
For those who don’t know, the game provides co-op zombie-killing for up to six players at a time, with unlockable persistent perks to level up your character. Add in Solo mode for offline play, more than 15 weapons, 9 zombie types, slow-motion ZEDtime. Shotguns, chainsaws, flamethrowers… not to mention a machete, fire-axe and much more. Weld doors shut to try and channel the specimens, buy time to heal up and reload. Even configure your own waves of zombies with the in-game tools – or use the SDK to create complete new maps to play on. Not forgetting over 40 Steam Achievements, access to your Steam Friends list, server browsers and all the long-term support the community has come to expect from Tripwire Interactive!
