Prison Architect’s Alpha 6 update has been released by Introversion Software. A risk level has been added to the prisoner category, and the inmates also have their own backstory including prior convictions. Each prisoner has its own threat level, like most, and you can read more about the update on the forums. Introversion notes the update comes with some hiccups, and plans to allow new prisoners to arrive are coming. A video is below. Thanks, Eurogamer.
