The folks at Undead Labs have released some behind the scenes footage taken around their office which just happens to contain the first substantial look at their open world zombie survival game, Class3. The footage (taken from the alpha version of the game) shows off the game’s physics at work, as well as the game’s protagonist boarding up windows to help fend off the coming hordes of zombies. For the action junkies out there, don’t worry, he does shoot a few zombies. Additionally we’re providing you with some videos of motion capture done for the game. If you’re a fan of the zombie phenomenon, take a look at the clips after the jump.

While we haven’t had any indication as to when Class 3 will be released, we’re hoping that it makes it onto XBLA in 2012. You can never have enough zombies! Although it may come under a different title before all is said and done, Class3 is an ambitious title that you should definitely keep an eye on.
