Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game may or may not change significantly over the course of development. If you are not excited to play this game in its current state, then you may want to wait until the game progresses further in development. Learn more

What the developers have to say:

“Prison Architect is currently in Alpha, which means we haven't finished it yet - it's full of bugs and glitches and you're not going to get a polished experience if you buy it at the moment. What you will get is early access to a bullfrog-style Prison Management Sim that over 250,000 gamers have already thought is worth a look at.



When you buy early access we also guarantee to give you a free copy of the full game once we've finished and you'll also get monthly updates which include new features and bug fixes. But that's not all, you can also pre-order a copy of the PA art book and Soundtrack (like the game, these aren't ready yet, but you'll be the first to get access when they are launched), or buy a pack that includes the whole Introversion back catalogue (we've made some seriously awesome games). Finally, you can immortalise yourself into the game, by naming a prisoner and writing his bio. Everyone that plays PA will see your bio and know that YOU helped to make Prison Architect a reality.



But that's not all, we also want to get your feedback and comments on the game and want you to help us to direct the development process. Tell us what you like and what you don't like and what you want us to work on. We've got a great community of Prison Architect early adopters and we'd love for you to join in - just head over to http://www.introversion.co.uk/prisonarchitect/developer/register.html once you've bought the alpha.”

Prison Architect Alpha 26

Alpha 26 has been released! Here is our video demonstrating the work done this month.
https://www.youtube.com/watch?v=0p3EgTP2FYA&list=UUuWAgvyiWcBeZ8sT0sJZyBg

This month was dedicated to our second Bug Bash - which means all the programmers at Introversion focussed exclusively on bug fixes for an entire month. We've spent the month slogging our way through the bug database and fixing the highest priority issues to bring you a slicker, faster, better, less buggy Prison Architect. But that's not all - NOT ONLY have we fixed 39 issues and resolved 550 duplicates, we also present a brand new feature! Tell your mates, put it on facebook, set twitter on fire, let the world know that Prison Architect now comes with a digital clock.

At the very start of the month we decided we would aim to resolve the food/kitchen/chefs bugs as a priority. If you are a regular player you have no doubt experienced chefs being dumb, food going to the wrong canteen whilst inmates starve elsewhere, and various issues around kitchen resources. In many ways the food distribution system is the most complex of all of the AI within the game, and none of these problems are 100% solvable simply because everyone builds prisons differently, and there are many variables to take into account. Players can build one or many kitchens, one or many canteens, and can hire chefs or use prison labour. They may intend one kitchen to cook for everyone, or multiple kitchens to cook for one canteen, or multiple kitchens to cook for multiple canteens. If that wasn't bad enough, each kitchen may have a security designation limiting which prisoners can work in there when, and the canteens may be designated as well such that only certain prisoners can eat there, and each category of prisoner can potentially eat at a different time of day. Sometimes you may have a mixture of prisoner types in one canteen. Just figuring out how many prisoners will be eating in a single canteen at a certain time of day is a very complex AI problem. But thanks to the work done this month we think you'll find the whole system much more reliable from now on.

We also resolved lots of nasty bugs to do with zoning your prison into different categories of prisoners. Eg prisoners failing to go to reform programs, or visitations failing, all due to the AI not taking into account the security designation of different sectors.

Normal service will now resume, and we will be getting back to adding new features to the game. See you next month!

Alpha 25 launched

Alpha 25 has been released! Here is our video demonstrating the new features:
https://www.youtube.com/watch?v=8Z2W05vvIKU

Big changes this month! This is one of the biggest updates we've ever done. Alpha 25 was motivated by seeing prisons that just run themselves - and can even be left running overnight, without anything bad happening. This doesn't sit right with us, and running a prison shouldn't ever be something that can be done fully automatically. This month we've introduced a whole series of new systems and balance changes that bring unpredictability back to your prisoners.

= Reputation
New prisoners sometimes have a reputation, shown when highlighing them or in their rap sheet.
Nb. Existing prisoners (in alpha 24 save games) will not have any reputation - only new arrivals
The reputation specifies unusual abilities or traits they may possess, which affect their behaviour.

- 50% of reputations are known when the prisoner arrives. The other 50% can be revealed through your informants.
- All prisoners have a new "Character" tab in their rapsheet, which gives details on their reputation.

  • STRONG hits harder with each punch during fights
  • TOUGH can withstand a lot more punishment in a fight. He can also sometimes withstand being hit by a Tazer
  • VOLATILE liable to kick off without warning and for no reason
  • STOICAL will not become suppressed when locked in Solitary
  • SNITCH a known informant, and as such his life may be in danger. Don't leave him alone with other prisoners for too long
  • DEADLY a master in lethal combat moves, and can sometimes kill with a single hit
  • EX LAW was once a Police Officer, or some other law enforcement profession. His life may be in danger
  • COP KILLER guilty of murdering a Police Officer. Your prison guards may be unable to restrain themselves when subduing him
  • FEARLESS not intimidated by the sight of Armed Guards, and is less likely to surrender during a fight
  • QUICK an unusually fast runner
  • INSTIGATOR sows seeds of discontent in all those nearby. When he causes trouble, nearby prisoners will feel compelled to do the same

- In some cases, the prisoner will have a high degree of a reputation, eg "Extremely Strong" or "Extremely Volatile".

- In a very small number of cases, you will receive a LEGENDARY PRISONER.
These guys have a potent mix of the above list that makes them very dangerous.


= New Prisoner Categories
To help deal with the new troublesome prisoners, two new categories of prisoner have been created.
Prisoners must be manually assigned to these categories.
These new categories have a corrisponding new Zone in the Deployment screen, and a new Regime column.

- Protective Custody
Useful for hiding your snitches, ex law enforcement etc in a safe zone where they cannot be attacked
Nb. Informants sent to protective custody lose coverage quickly (out of the loop)
Nb. During riot conditions, some of your most dangerous prisoners may attempt to attack the protective custody wing

- SuperMax
If you simply cannot control a particular prisoner, move him to supermax.
Allows you to segregate them away and instigate strong lockdown and security measures


= Escape Tunnels Overhall
Escape Tunnels have been rebalanced, and are now viable once again
Prisoners in neighbouring cells will team up to try to dig a combined escape tunnel.
They can share any tools they have during the operation
Many weapons can now also be used as digging tools, eg Knifes, Forks etc
Guard dogs are now more reliable at discovering tunnels, and will mark the suspected spot with a small flag.
Searching a cell now has only a low chance to discover an escape tunnel, UNLESS the prisoner is digging it when the guard enters!
To discover a tunnel for certain, dismantle the toilets in the cells you suspect.


= Confidential Informants (continued)
- Any single informant now has a maximum coverage of 50% at the time he is hired
- An informants coverage will slowly increase over time (beyond 50%), so long as his suspicion is low and he is not 'active'
- The Informants overlay now shows the highest level of suspicion ever reached by an informant, as a black line.
- You can now highlight and select prisoners and staff etc in the Informants window

- Informants now reveal Assassination Targets - ie prisoners who will be attacked if left alone for too long
This is shown as a red crosshair over the prisoner.
(Known informants / Snitches, ex law enforcement etc)


= Game Balance changes
- Prisoners responsible for a serious injury will have their category automatically increased (min-sec to medium, medium to max-sec)

- Prisoners responsible for a murder will be charged and given an additional 25 year sentence,
and will automatically reclassify as Maximum Security (if they weren't already)

- The 'temperature' of your prison must now be at least 33% before a riot can start

- 10 Prisoners must be rioting before a prison-wide RIOT status can occur.
To stop the riot, you must reduce the number of rioting prisoners to 3 or less.

- Tazer Training Program
All regular guards must now pass the Tazer Certification Program before they are permitted to use a tazer.
This takes place in the classroom and is led by the Chief.
The staff window now shows which guards have body armour and tazers.
Nb. When loading an alpha 24 save, all Tazers owned by regular Guards and Dog Handlers will be confiscated, and a refund given.
Nb. Dog Handlers can no longer carry Tazers.

- Prisoners can now pick up weapons from their current room during fights, escapes, riots etc. (Based on what is available as contraband)
- The Morgue is now a source of Knifes and Scissors
- Prisoners can now improvise a Shank in the Workshop
- Prisoners can now improvise a Baton in the Cleaning Cupboard (by snapping mops)
- Prisoners can now improvise a wooden pickaxe in the Workshop (for digging tunnels)


= Mod System Continued
- Now supports multiple active mods at once, even if those mods all add their own new graphics
- New property to set material auto-consumed on job
- Can now auto-order raw materials

- NEW SCRIPT COMMANDS:
GetNearbyObjects - Get a list of all nearby objects of a certain type
NavigateTo - Instruct an entity to go somewhere
ClearRouting - Clear an entity's destination

- Panic Button mod
A new 'official' test mod that adds a Panic Button to the game, using the new script commands.
Injured staff members will run to it and press it, and guards will be summoned to the area.


- Fixed : You can no longer place Foundations that you cannot afford

- 'Unlimited Funds' option in 'New Prison' screen.
Spend as much money as you like while building your prison - a more pure sandbox mode.

- Prisoners will now be assigned to Rehab programs more reliably, when addicted/alcoholic/withdrawn

Reviews

“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.”

About This Game

Build and Manage A Maximum Security Prison.

Prison Architect is the world's latest Prison Management Sim. Starting with an empty plot of land you must construct a holding cell with basic water and electricity to house your first batch of prisoners, to buy you enough time to create a proper cell block. You'll need to hire some guards, get some showers built and unless the kitchen is up and running with chefs working away you're going to end up with a riot on your hands. From there you take your prison in which-ever direction you like. A monsterous super-max or comfortable center for rehabilitation, the choice is up to you.


Prison Architect is currently in Alpha which means that the game is playable, but still in development. Not all features are implemented yet and there are many bugs that may affect gameplay. We are currently releasing monthly updated builds which include new features and bug fixes. By buying the alpha you will automatically be gifted a free copy of the full game when it's finished.

Early Access Review
I've enjoyed creating my own prison and watching the prisoners suffer. There are lot of bugs in the game which can be ignored since they don't affect the gameplay a lot. You can buy the plot lands around you in case you want to expand your prison to be bigger (I prefer mine to be small, its easier to control). I got the game on sale for like $10 which was a good price considering how expensive it is. It's definitely worth your time playing, you'll be addicted watching your prisoners move around or watch them get in a riot because you've been treating them badly (never had gotten a riot in my prison before. I'm proud of myself). I give the game a 9/10 since it still has bugs in it. Buy it to support the developers they made a great game and its still being worked too! Buy the game. You won't regret it.

I love tycoon/building games, like Sim City, rollercoaster tycoon, etc. This game doesn't disappoint. In fact in some ways it's better.

PA offers you the fun of building something, i.e. a prison, but with the details of running it as well, which you don't get with every game. You get to decide a lot more then some broad overviews of the world. You can deicde how everything works, when it works, cut cost, spend more, care for the prisoners — or don't it's up to you.

The game does have some issues, such as on MAC I don't see any of the proper icons/graphics when I play the game outside of SAFE mode. It loads into your save fast and then fromt here your fine. Occasionally something breaks in the game and the devs are fast to respond and deploy a fix or include it in the next update.

Personally this game could be released now, however I understand and don't want people to buy the game and it have some bugs and think that it was hald-♥♥♥♥♥ because of a a few minor problems.

Its an enjoyable prison building and managing simulator. I liked it, but I didn't love it nearly as much as I do the few games I play regularly, so, while a great game, it just isn't really "my thing".

I would recommend purchasing it if you are into this kind of game, especially if it is on sale.

Oh look, let's play Prison Architect, just let me check the time to be sure. Ah, 10 PM, cool.

A few moments later

That'll do it, now this there and let them come in again.

O dear, it's 3 AM.

That is how my game usually goes, time really flies past which is a really good thing.

Spent three hours planning,
Had my first set of prisoners,
Forget to enclose prison,
After yard time they all just walked off to freedom.

10/10

After many let downs with other Early Access games this one gives me hope. Constant updates and enough of a full game to feel complete make this worth of a purchase.

Designed my new prison which took me 6 days, finally, i was so happy that it is mostly done so i waited for my new inmates to arrive, just as soon first 8 arrived, guard took one of them to his new cell and this very instant this prisoner overdosed from drugs and died within 20 seconds from the beginning.

For an early access game Prison architect plays surprisingly well with only some problems with the ai, and occasional construction glitches.

It is the most highly addictive game Ive played since FTL and Ive truly enjoyed every hour I've put into.

Also with workshop content already available to alter textures the community should make the game even more enjoyable in the future.

In the first, i think this game is simply easy and a little bit frustrating. well, i was wrong. This game is REALLY FUN and REALLY FRUSTRATING!!! let me give you a real deal advice: DO PLAY THE TUTORIAL FIRST BEFORE YOU MAKE YOUR OWN PRISON. Because this game is similarly like Grand Age of Rome or Tropico, some buldings are requiring other building, or some buildings are requiring a blue print which this blue print won't uinlocked unless you hire a staff, and the staffs are won't unlocked unless you hire a warden, and a warden isn't working unless you build him an office, and that damn office won't functional unless you put some requiring stuffs!! what the hell, right?!! So i repeat, DO PLAY THE TUTORIAL, BECAUSE I PLAYED FROM 12 PM UNTILL 5 PM JUST TO REBUILD ALL OVER AGAIN, AND FROM 5 PM TO 8 PM JUST TO REDO WHAT I'VE DONE IN 12 PM TO 5 PM LOL. but i REALLY ENJOY PLAYING IT. 9 / 10 untill the final vesion come out.

This game is addicting! Reminds me of the days I spent building theme parks and zoos. This is just A LOT more violent.

You'll start with a prison and it'll suck. The next one will suck less. The third one may actually start getting halfway decent.
The more you play... the more you learn... which makes you want to play more... learn more... a neverending cycle!
IT IS SO MUCH FUN WHOOOOOOOOoooooooooooo

This is going to be an amazing game when it fully releases. It has so many details and features, and it's still in alpha! One thing I would really appreciate though, is a better tutorial, or at least better explanations of some things, like the receiving area.
