Tripwire's Killing Floor is a British zombie game

Red Orchestra: Ostfront developer Tripwire Interactive is making a zombie game. A British zombie game.

Called Killing Floor, it's six-player co-op affair. See on IGN.

It's being described as "Dead Alive meets The Re-Animator" and a "grindhouse exploitation horror film".

When asked if it will draw comparisons to Left 4 Dead, designer John Gibson says that it relies on a sense of dread more than an in-your-face wave of zombies.

"It is sort of like George Romero meets sci-fi. L4D goes for the constant, frantic, in-your-face fast moving zombie shock value", he said.

"On the other hand, Killing Floor works to build a palatable sense of dread as a wave of specimens. The enemies in KF shamble towards you. That's not to say it's not action-packed; I'd just say there is more of a variety in pacing and in the types of enemies you fight."

The first person shooter should be out sometime this year. No word yet on what formats.
