State of Decay is set to launch on Xbox Live June 5 for 1,600 MS Points ($20). The news comes via Major Nelson on Twitter, with Undead Labs confirming the date on its blog. No word on a date for the PC port yet.
Undead Labs announced it was working on a zombie MMO in 2009. In early 2011, the company revealed a title codenamed Class3, which was positioned as an open-world zombie game targeting XBLA that would serve as a precursor to its announced MMO. In 2012, Undead Labs re-branded the downloadable game as State of Decay, which still retains its focus on survival mechanics in an open-world environment.
