The upcoming zombie survival game from developer Undead Labs has been revealed. State of Decay is a new, open-world game in development for Xbox 360 and PC.

The announcement notes State of Decay is a 3rd-person action game "set in a dynamic open world," where player actions and choices generate content within the game. "You choose where to make your stand, designing and fortifying your home base, performing daring raids for food and ammunition, and rescuing other playable survivors with unique talents," the developer says.

Head over to the official website to learn more.

State of Decay was previously codenamed Class3. Undead Labs is also working on a MMO, Class4. It's unclear if the PC version of State of Decay is in fact the planned MMO. [Update: Undead Labs says Class3 (State of Decay) is coming on Xbox and the PC. Class4 is the online world version of the game, and it's not built yet.]
