State of Decay's emphasis on resource scavenging and combination allows for some pretty tricky approaches; watch as a group of zombies go nuts over a set of firecrackers while our heroes sneak off with the loot.
For those with short memories, State of Decay is a co-op zombie effort formerly knows as Class 3, which is expected to be the basis of an eventual MMO. In this suddenly saturated zombie market you may be crying foul, but State of Decay dates back to late 2009 at least and has a lot of neat ideas like building bases and shaping the world around you.
It's expected on PC and Xbox 360, but has not been dated.
