Now, thanks to a new trailer, we know that the game is officially called State of Decay and it's also coming to the PC. Whether it's an MMO or simply a precursor to the rumored Class4 MMO is still undetermined. All that said, the trailer shows off plenty of open-world third-person shooting action, zombie-centric gore, and even a muscle car and the requisite rusty old pickup truck.
Undead says that State of Decay is set in an "open sandbox world [that] develops in real-time" and that gameplay involves "designing and fortifying your home base." Click past the cut for the full video.
