Prison Architect Wiki

Island Bound is the 2nd expansion for Prison Architect, announced on 2020-05-14 and released on June 23, 2020.It was released along side with the free content patch The Rock.


This expansion will allow you to create island compounds with no access road. You will have to bring your logistics game to a whole new level with these prisons, as you need to use a variety of new tools to make sure they run as intended. From ferries to helicopters, you will be able to maximize efficiency by linking them to specific deliveries – but be careful, as this also means more access points to sneak in contraband into your prison!

Luckily, you will also have new security objects that will allow you to inspect deliveries and prisoners as they enter the prison, or at key security checkpoints. You will also have access to additional emergency services when things get out of hand. Air FirefightersElite Ops TeamsAir Paramedics – we made sure you have all the support you need when things take an unexpected turn.

Finally, you will have access to new tiles and objects to customize your island!
