We've totally redesigned the zombies to be fully "physics ready" - this means they fall over obstacles, you can push them around, unbalance them with a decent shot and use defence barriers.
There's totally new sounds..
A brand new "Stadium" map for some relentless close quarter fighting..
New environmental effects!
All improved blood and vein particle systems!
