Prison Architect Update 1
Posted by Chris on 13rd November 2015
And we are back! Update 1 has been released. Steam users will be automatically updated. Non-steam users can download the latest version from the builds page here:

You need an active forum account to access the builds from our website. If you haven’t already done so, please register your game here to gain access to the builds, the private forums, the bug database and the wiki.

Here is our video demonstrating the new features:

= Shared Cells
- New room type: Dormitory
- New furniture: Bunk Beds

A Dormitory can house any number of prisoners, based on the number of beds installed
Dormitories can be small eg 2x3, replacing the normal Cell, allowing for two or more inmates to share a cell together
Or Dormitories can be large, with shared showers, toilets, phones, tvs, recreational facilities etc.
Better facilities will result in a higher room grading, which will have a positive effect on your inmates

= Prisoner Intake (continued)
There are now several different modes of Intake that can be set for your prison
Choose your mode from the Intake report

- CLOSED No inmates will be brought to your prison
- FILL CAPACITY Inmates will be brought into your prison when available, until your available capacity is full
- TOTAL PRISONERS You set the total number of prisoners desired, and the Intake system works to fill that number
- NUM PER DAY You choose the number of prisoners to bring in each day (The old method)
- ALL All available prisoners will be brought in every day

= Escape mode (continued)
Escape mode was deemed too easy and unbalanced, and several features have been nerfed.

- Damage done to a prison and its staff is now repaired automatically,
once the player surrenders or is knocked out.

- All staff killed are replaced with new hires
- All fires are extinguished
- Burnt down walls now get construction jobs created to replace them

- All ranged weapons now have limited ammo.
Nb you can press G to drop the current weapon.
- Shotgun : 6 shots
- Pistol : 6 shots
- Tazer : 1 shot
- Assault rifle : 30 shots

- If you steal an item from a room, there is now a three hour timer before that item can be stolen again from that room.
This will put a stop to whole teams of escapees stealing knives from the kitchen.
Nb these timers end instantly when the player surrenders or is knocked out.

- Reputations rebalanced
- Skilled fighter: chance to disarm opponent now reduced to 20% per hit, down from 30%
- Extremely deadly: chance to kill reduced to 15% per hit, down from 30%
- Ranged weapons are no longer made more powerfull by the Strong/Deadly reputations
- Ranged weapons no longer disarm opponents when the attacker has the Skilled Fighter rep

- Improved game over screen to stack up victims in the same way as the intake report's prisoner preview.

- Gangs rebalanced
Rebalanced the chances of gang members and leaders arriving,
to make gangs a more likely occurance.
- Doubled the chances of receiving gang members at intake
- The chance of an incoming gang member being a leader is now much higher
- The probability of receiving a gang leader also increases as the size of the gang increases.

- New translations
Greek, Romanian, Swedish, Turkish, Spanish, Portuguese

- no more saving on escape mode gameover screen
- Items still loaded on trucks dont get search jobs during shakedown
- deployment menu has the correct default selected based on your research
- fog of war turns on sooner on GABOS level
- error sound only plays once when unable to afford objects

Prison Architect Version 1.0 launches!
Posted by Chris on 6th October 2015
Congratulations everyone, Version 1.0 has been launched!

Here's is our video demonstrating the new features live at EGX:

Changes in Version 1.0:
Campaign Story
The perfect place to start for new players.

Chapter 1 : Death Row (The Introduction from the Alpha)
Chapter 2 : Palermo
Chapter 3 : GABOS
Chapter 4 : Conviction
Chapter 5 : Bootstraps

Escape Mode
You can now load any prison, and attempt to escape from it, in this brand new game mode.
Steam customers can load any Steam Workshop prison, or even use the 'Random'
button to be sent to a random steam workshop prison. (Experimental)
There is a 'HELP' button that you can click on, in the bottom right of the screen.

Use WASD to move around, and aim with the mouse.

- You can steal weapons and tools from all the rooms you'd expect.
- Stash your contraband to avoid being caught
- Earn Reputation points by starting fights and smashing up furniture.
You will receive bonuses for knocking people unconcious, and additional bonuses for kills.

Spend those points to upgrade your character with any of these reputations:
Strong You hit harder
Tough You can take more hits
Deadly You have a chance to kill with one hit
Quick You can run faster (hold SHIFT)
Instigator Nearby prisoners will fight when you do
Skilled Fighter You can disarm opponents

- You can also spend rep points to recruit other prisoners to your group.
They will follow you around and will assist during fights.

- If you have a digging tool you can dig an escape tunnel from the toilet in your cell.
- Win the game by escaping with your entire team.

There are two types of collectable item in the game.
As you discover them they will be added to the Extras menu.

- Polaroids : All story based polaroids. Some are shown during cutscenes.
Some only occur in the sandbox and must be found.

- Game Bible : The game design notebook has been scanned and can now be found
throughout your prison. Keep your eyes out for scraps of paper on the floor within the sandbox.
Click on those scraps to unlock another page.

Special Wardens
You can now select from one of six wardens, when creating a new prison.
Each Warden brings a special ability to the game.

- The Warden : The default warden, offers no special abilities.
- The Lobbyist : Halves likelyhood of Violent/Lethal/Deadly inmates arriving
- Rita : Diminishes effect of Stoical / Fearless. Doubles effect of Suppression.
- J.W.Periwinkle : Guard dogs have a 50% chance to immediately uncover tunnels
- The Pacifier : Permanent 25 point reduction in prison temperature
- Saphara Acknova: Corruption! Receives a backhand payment for all contraband found

We are working to translate the game into as many languages as possible.
More languages will be coming in the first update.

We currently have translations for:
English, Czech, Finnish, French, German,
Italian, Korean, Norwegian, Polish,
Brazilian Portuguese, Russian, Simplified Chinese

Education grant (continued)
The education grant has been rebalanced and made easier.
You now need 10 prisoners to pass the foundation course, and 1 prisoner to pass the general education course.

Event System (continued)
The event system has been rebalanced and is now much less destructive.
Specifically, the 'politician demand' event and the 'Virus outbreak' event have been nerfed.
Events occur far less frequently.
Many other small tweaks to make the event system better.

Prison Architect Alpha 36
Posted by Chris on 28th August 2015
Alpha 36 has been released! Here is our video demonstrating the new features:

This is the last ever alpha video for Prison Architect, and we will be launching version 1.0 in October. But fear not! We are planning to continue the cycle of monthly updates beyond version 1.0, including new videos to go with each update each month.

Here are our new features:

= Random event system
Random incidents, disasters and challenges will occur during your game, providing extra difficulty and unpredictability.
This is an optional system, and is enabled from the "Create new prison" screen.

- Events will not happen during riots, or if you have less than 50 prisoners on site
- Events are less likely if there have been deaths and escapes recently.
- Sometimes, rarely, several events may occur at once.
- All events have an EXTREME version, which is very rare, and much more severe.

Your power station catches fire. Can only occur if your powerstation is overloaded.
EXTREME version: Your power station explodes, damaging buildings/equipment/people nearby.

A cooker in the kitchen catches fire. This can cause havok with your mealtime arrangements!
We recommend you build sprinkler systems in key areas to mitigate this.

A random number of prisoners will be transferred into your facility within the next hour.
EXTREME version: All of the prisoners belong to the same gang, and you are probably fucked.

A prisoner injures himself on the equipment in the workshop, and requires medical attention.
Prisoners injured this way get the "Bleeding" status effect. Get them to a doctor quick!

A random section of your wall or fence collapses. Get it rebuilt before we have a mass escape!
We always recommend double outer walls, and this gives yet another good reason.

A prisoner comes down with a highly contagious virus. The virus will spread to nearby inmates, so try to isolate them.
Prisoners suffering from this virus will look sickly, move slowly, and vomit a lot. Some will fall unconcious.
Your guards will try to take confirmed cases to the infirmary for cure.
Some inmates will go to the infirmary themselves, but only when they are let out their cells.
EXTREME version: Some prisoners will eventually die from the virus if left untreated.

You discover that several inmates at your prison are federal witnesses in an upcoming prosecution.
Unfortunately, somebody has put a price on their heads and they will all be assassinated in the next few hours.
Find out who there are (using your Confidential Informants), and get them moved to Protected Custody.
Once the timer hits zero, they will all leave the prison to attend the court hearing, and will not return.
(Most likely living out their lives in federal witness protection, holding their breath every time they start their cars)

The Mayor is under political pressure to appear to be doing the right thing.
He will from time to time phone you and demand certain changes to your prison, in the public interest.
The demand is always temporary - after a few days, things return to normal.
However Failure to comply will result in a heavy fine.

- TV Removal Due to public pressure, all TVs must be removed
- Weights Removal Due to public pressure, all Weights Benches must be removed
- Less Food Provide smaller meals with less variety, to try to save on costs
- Remove Visitation For security reasons, all visitation must be halted

From time to time the prisoners in your facility become so frustrated that they demand changes.
It's your choice to comply or not, but the prisoners will not be happy if you refuse.

- Less Work Prisoners wish to work for less hours during the day
- More Sleep Prisoners want longer to sleep at night
- More Free Time Prisoners want more free time during the day

- Logs will now be automatically exported, unless EITHER
- You have at least one carpenters table
- OR You have a running carpentry program
Nb. This obviously requires an Exports zone near the road.

- The CEO's letter is now made of a graphic and a (localisable) string in the language file.
This should make it much easier to translate into multiple languages.

= Bug Fixes
- 0009322: [AI & Behaviour] The mere presence of a shop is stopping prisoners from wanting to do carpentry (Icepick) - resolved.
- 0009713: [Other] Crash after Assertion failed : 'index < m_numItems' (John) - resolved.

Prison Architect Alpha 35
Posted by Chris on 30th July 2015
Alpha 35 has been released! Steam users will be automatically updated. Non-steam users can download the latest version from the builds page here:

You need an active forum account to access the builds from our website. If you haven’t already done so, please register your game here to gain access to the builds, the private forums, the bug database and the wiki.

Here is our video demonstrating the new features:

= Gangs (continued)

- Gang Leaders
Sometimes a Legendary prisoner who arrives through Intake will also be a gang leader.
They will immediately assume control of their gang, and will establish a leadership hierarchy.
Can promote gang members into Lieutenants, up to a maximum of 1 lieutenant per 10 soldiers.
Can recruit non gang members into the gang. (Must visit the prisoner first)

Gang members are fiercly loyal to their leaders:
- They will become angry (temperature increase) if their leader is being punished in Solitary or Lockdown
- If a gang leader is killed, the entire gang will immediately try to start a riot

- Gang Territory Capture
Gangs will attempt to take control of key areas of your prison.
The attempt is called a 'Play', and is led by a Lieutenant.
He will gather a group of gang members together and give them instructions.
The soldiers will then proceed to the zone in question, and assert their authority over that zone.
If they are unchallenged, the territory will turn their colour and they will have ownership of it.
The player cannot build or change room setups within gang territory

- Captured Territory
Once captured, territory shows up in the Gangs view as the colour of the gang who has claimed it
Rival gang members are not permitted into the territory
Non gang members can enter the territory and use the facilities (eg Phones), but must pay Protection Money to the gang
Gangs accumulate money from non gang members this way, and will use the money to buy equipment such as stolen weapons
From time to time a lieutenant will arrange a 'Play' to revisit the territory with a group of soldiers, as a show of force.

- Contested Territories
Sometimes a gang will be strong enough to take a territory from a rival gang.
They will only attempt this if they have sufficient numerical advantage.
A lieutenant will arrange a Play and will send enough soldiers to take the territory by force.

- Eviction
Once a gang has claimed a territory, they must be Evicted to remove their influence.
Click on the EVICT button in the gang view to begin this process.
Any gang members within the territory will immediately turn hostile.
Nearby gang lietenants will arrange new 'Plays' in an attempt to re-capture their territory from your guards.
Once you have defended the territory for 24 hours, the ownership reverts to 'Unclaimed'.

- Securing a territory
With enough guards, you can protect a territory against any gang control.
Nb this can only be done with an unclaimed territory - any gangs must be evicted first.

- Security Rooms
Security rooms also count as territory, and are automatically guard controlled.
Guards can project their power from security rooms to any neighbouring territory.
Eg a security room with 10 guards inside will 'project' 10 guards onto all neighbouring yards, common rooms etc.
Nb. 'Neighbouring' means there must be a door between the security room and the yard/common room.

= Contraband trading
All prisoners can now trade their stolen contraband with other prisoners for money.
Prisoners will sell items they don't particularly want, and use that money at the shop or to buy other items from other prisoners.
The price of any item is based on the supply and demand of that item within the prison.
The approximate trade prices of all items can now be seen in the Intelligence / Dangers view.

- Ranged Weapon accuracy
All ranged weapons have had their accuracy nerfed (previously 100% for anyone).
Tazers: 60% accuracy
Tazers used by Armed guards: 70% accuracy
All other ranged weapons: 70% accuracy
All other ranged weapons used by Armed guards: 90%
