Undead Labs has confirmed the release of State of Decay. It’s going to happen tomorrow for Xbox Live Arcade. The game has also been developed for PC, but the release date for that hasn’t been announced yet.
The game was announced in 2011 as Class 3, and just last year it came up in the news again as State of Decay. According to Undead Labs, the game is a “3rd-person action game set in a dynamic open world,” and that “the open, sandbox world develops in real-time, shaped by your actions, dynamically generating content based on your choices and the ever-increasing zombie threat.”
