For this update we've focused on a new system called Fog Of War, which changes the game in a number of

ways. Internally we refer to this as the Visibility system, because you now lose visibility of the indoor areas of your jail gradually over time. Your guards are the only staff members who can "unveil" the hidden areas, and if you lose visibility of an area you have no idea what sort of things are going on there. This ties in very closely to the Alpha 2 update, because you now have to use Deployment and Patrols to create pathways for your guards to walk along to ensure your entire jail remains fully visible at all times.

Fog Of War

  • You now lose visibility of the indoor areas of your Jail over time (Roof covers up the area)
  • Guards reveal the area around them - spread them out to keep your jail fully visible at all times
  • Fog of War is optional and can be toggled when creating a new sandbox

CCtv system

  • Unlocked by the Security Chief after Deployment
  • CCtv cameras can be used to uncover fog-of-war instead of Guards
  • Cctv cameras require monitors - each monitor station allows 3 cameras
  • Monitor stations require Guards nearby watching them (One guard can watch a lot of monitors)


  • Researching "Deployment" now unlocks Guard Patrols immediately, rather than requiring a separate research project
  • Guards who are deployed within a sector will now stay within that sector unless ordered away by the player
  • You can now press R to rotate objects during placement
  • You can now press Q and E to zoom in and out
  • Metal Detectors improved
  • Low powered electrical items no longer take damage from water, nor electrocute people in water
  • High powered electrical items should never be allowed to touch water ;)
  • Holding Cells no longer count towards your prison's capacity. (And no longer affect intake of prisoners)
  • You can now disable the checkerboard room pattern if you wish, to provide a cleaner look (Controlled by preferences option "RenderRooms")
  • The PC executable now has an icon
