State of Decay is an open-world, zombie-themed survival RPG from Undead Labs, a studio led by Jeff Strain formerly of Blizzard and ArenaNet. The game puts players into a world where their decisions will matter, resources are limited, and there are hordes of hungry zombies on the loose in a world where the laws of civilization no longer apply.
In order to survive and thrive, players will engage in tasks such as supply raids and negotiating with other survivors for things such as ammo, food, and supplies for shelter. A.I. survivors can also join with the player and help build defenses, shelter, and repair items. With enough success, these A.I. characters can become playable. With the zombie threat out there, anyone can also become what they fear.
