"The Clink" Update is Now Live!

It's Live!

Our first update from Paradox Interactive and Double Eleven is available now.

Patch Notes
  • 4 new floor tiles and 4 new wall types added
  • Increased the number of foremen that can be hired for larger prisons where foremen also teach programs
  • Added new sprites for missing orientations to many items. Aiming to provide full set of rotations to all objects in the future
  • Added “Guard Response” button that allows players to immediately send existing nearby guards to a location, instead of needing to hire additional guards to deal with incidents
  • New “Tunnel Search” button that allows the player to have guards search all toilets only, for hidden escape tunnels
  • Additional Quick Rooms added to the Quick Build menu, for quicker and easier room construction
  • Following prisoners and staff has been made easier, you can now double-click on them to enable

Mod Support: Special thanks to badAim and Murgh for helping us identify this issue
  • New content is being added to a brand new tileset file
  • The current tileset.png has been made larger, allowing for more custom content

Known Issues:
We're investigating an issue where the game crashes due to the update. We'll update you as soon as we have a fix! UPDATE - we found the issue. Working on deploying hotfix

We also accidentally changed the size of the boilers. Hotfixing that as well!

UPDATE 2: hotfix is now live. Boilers and the crashing should be fixed. Please let us know if there are still crash issues

UPDATE 3: We put out another hotfix so your prisoners no longer are making telephone calls from containers of bleach! Also, they are sitting properly at tables!

Thanks for your patience with these bugs. We rushed this free update to bring it to you ASAP, and in hindsight we realize that more work needed to be done to assure quality. We apologize for this, and promise a MUCH smoother release for our next free update.

Thanks again for your support =)

Name in Game Discontinued on August 6th

As mentioned on our last stream, we made the hard decision to stop updating the "Name in the Game" feature on August 6th. The manual labor involved in the name process would have cut down on the time we had to make bug fixes and create new content for the game.

Rest assured, all names will stay in the game! So make all the last edits and submissions before August 6th and you'll forever be memorialized as a prisoner of Prison Architect

Instructions for Submitting a Name or Editing:
  • Visit and log in to your Introversion Forum account.
    - If you haven’t created a forum account, you can register one here:

  • If you bought from Steam, you will have a CD Key that begins with PBIOSM that you can use to verify your "Name in the Game" purchase. Otherwise, if you bought from Introversion directly, the registration application should be able to check the purchase database that you have purchased "Name in the Game" tier or higher using your email address.

  • Once the registration process is complete, this same register link will allow you to edit your prisoner’s biography.

  • After submitting the biography, please allow a few days for the support staff to approve your update.

If you're having trouble finding your game CD Key, please reach out to the store from which you purchased the game.

If you require assistance after following these steps, please reach out to us on Twitter:

“Prison Architect chills me to the bone. If played haphazardly it can be a wonderful farce rich with hilarious anecdotes, but played patiently and carefully it’s a horror game, a top-down voyage into the heart of darkness, an eternal raging fire I forever try but can only fail to douse.” RPS

"Prison Architect, to be sure, is an excellent game, worthy of comparison to its canonical inspirations, Dwarf Fortress and Bullfrog Productions’ 1990 construct-and-manage simulations. Few games can hope to match Prison Architect’s emergent storytelling, and fewer still can balance brutality and poignancy like it does." KILLSCREEN

About This Game

Build and Manage A Maximum Security Prison.

Build and manage a Maximum Security Prison. As the sun casts it’s early morning rays on a beautiful patch of countryside the clock starts ticking. You’ve got to crack on and build a holding cell to detain the job­ lot of maximum security prisoners that are trundling to your future prison on their yellow bus. As your workmen lay the last brick you don’t have a moment to let them rest as they need to get started on the first proper cell block so you can make room for the next prisoner intake. Once they’ve all got a place to lay their weary heads the fun can really start.

You’ll need a canteen, infirmary and a guard room, oh, and don’t forget to plumb in a toilet, or things will get messy, but what about a workout area? Or solitary confinement cells? Or an execution chamber?

Inspired by Dungeon Keeper, Dwarf Fortress and Theme Hospital and with over 1 million players having spent time inside, Prison Architect is the world’s best lock-­em-­up.

Story Mode

Prison Architect opens with the story of Edward, a man facing the electric chair for committing a crime of passion. This is followed by four additional chapters focusing on different characters and aspects of prison life. From Mafia Dons to power-crazed senators, Prison Architect has them all! To bring these characters to life, Introversion teamed up with award winning professional writer Chris Hastings, producing an enthralling tale of corruption and human misery set against the background of the modern prison industrial complex.

Escape Mode

Finished your supermax? Got guard dogs roving every corridor and prisoners eating out of your hand? Now you can live the horror by firing up escape mode and play as a prisoner hell-bent on getting the hell out of dodge.

Dig a tunnel, go for the armoury or start a riot and slip out in the chaos, it’s entirely up to you! Figure out how to escape from your own creation, or hit the random button and load one of the 12,000 prisons created by the steam co
