It's an RPG shooter that supports four player co-op as hordes of zombies are blown to bits, with character levelling up, side questing and weapon crafting. It's their "most ambitious" title yet.
It will also be gracing the PlayStation Network but it will be a self-published affair, and will launch around the same time as on Xbox 360, which also includes the PC version on Steam.
"The studio has been working very hard on All Zombies Must Die! for some time; it is our most ambitious project to date and we are thrilled it will be in the hands of the public very soon," said doublesix's James Brooksby. "We are delighted to be publishing the XBLA version with Square Enix and look forward to working with them on the game’s launch."
