Undead Labs recently announced that they would be partnering with Microsoft Game Studios to release their open world, zombie-survival video game. The as of yet untitled game will be released for the Xbox 360 on the Xbox LIVE Arcade and feature online multiplayer gameplay.
Game Synopsis from Undead Labs:
The end is here. Human civilization has been annihilated. The few, scattered survivors must band together, rebuilding civilization in a third-person action game packed with sweet guns, fast cars, hand-to-hand combat, and copious amounts of zombie gore. Players choose where to make their stand, designing and fortifying their settlements, performing daring raids for valuable stores of food and ammunition, and rescuing other playable survivors. The open world develops in real-time, shaped by player actions, with content determined by their choices and the ever-increasing zombie threat.
