Undead Labs' State of Decay, a game that has been very popular on Xbox Live Arcade, hits Steam early access today. Undead Labs are quick to point out that this is early release is not a finished version and in fact the game will only be playable with an Xbox 360 controller at first.
"What you'll see this Friday, if you choose to join forces with us to make the PC version kick ass, is a test version. It's not ready to be reviewed. It will not be perfect. It may still have crashes. What it won't have is a keyboard and mouse interface...not at first. Why not? Over the next however many weeks, we will be putting up versions of the keyboard interface and using your comments and feedback to make it awesome. Right this minute, the Early Access version requires an Xbox 360 controller."
As always if you opt to buy the early access version on Steam you're game will be updated once the full release is available.
