PlayXBLA and Undead Labs have started broadcasting at the moment (20:10) a new live demonstration of State of Decay , the new open world survival horror coming soon on Live Arcade (maybe even next week, according to a recent rumor). You can see in this page , but if you arrive after that ended, you can see the recording. Good vision!

Update : the live has had some technical problems and most of the time was not visible. There will be a link if they are put online.

Update 2 : there are four clips of gameplay from the demo. You can find them here.
