From the Introversion blog: Two years in the making and inspired by Dungeon Keeper, Theme Hospital, and Dwarf Fortress, our latest game tasks you with building and managing a maximum security prison. Go to www.prison-architect.com and pre-order the game now to get immediate access to the alpha. You’ll get to play the alpha straight away for Pc and Mac, and you’ll get access to the private Prison Architect wiki and forums where you can discuss the game directly with us. Every alpha customer will get the full game when it’s finished, for Pc, Mac and Linux, and if we are lucky enough to get a Steam distribution deal then we’ll give you a Steam key too. All our alpha builds are DRM free so you can install them on as many computers as you like.
