Update 11(20 Dec 2016)

Prison Architect Update 11

This frosty December, we give you guard needs:  no longer can you treat your hard working prison officers as robot gaolers. They're going to need their own toilet and canteen and your staff room is about to get a whole lot busier....

Failure to look after their needs will result in a whole gamut of industrial accident that's going to have a very bad effect on the welfare of your prison.

16 Jan 2017: Hotfix Update 11f released (See changelog).

Full Change List

= Staff Needs

Your security staff now have needs, in much the same way as prisoners. This is optional, and can be enabled when creating a new prison, or enabled from Extras -> Map Settings.

You must take care of your staff needs, or else your staff will begin to perform their duties badly.

The staff members affected in this update are:

  • Guards
  • Armed Guards
  • Dog Handlers
  • Snipers

These staff will have a semi random mixture of the following needs. Each need is similar to its prisoner counterpart, but also slightly different:

Staff will only make use of toilets in staff designated zones or staff rooms
Staff will eat in the Staff Room if you add a Serving Table. Or you can designate a canteen as "Staff Only" and they will eat there instead. Staff meals are more expensive than prisoner meals and are automatically delivered.
Staff hate to feel they are in danger. You can help with this need by equipping your staff with Tazers, body armour etc, as well as ensuring strength in numbers.
Staff get bored too. They can now make use of any entertainment so long as it exists within a staff room. Eg Pool tables, radios, TVs, etc.
Put some sofas in the staff room for this.
Same as prisoners, this is entirely based on the cleanliness of the surroundings.
This replaces the "tiredness" mechanic. Be sure to give your staff enough down time.

If staff are happy, this contributes in a positive way towards the temperature of your prison. Likewise if they are unhappy, this will make the prison "hotter" and lead to more trouble later.

If you do not take care of your staff they will become "pissed off", and begin to perform their jobs badly:

  • Sauntering around slowly when doing jobs
  • Less effective at searching for contraband
  • Less likely to actively look for trouble, more likely to turn a blind eye
  • Unwilling to put themselves in danger eg confronting gang members
  • In extreme cases, staff will take bribes in order to look the other way when searching for contraband
= Staff break times
  • You can now specify how much break time to grant your staff. Go to Reports -> Policy.
  • You can choose how long each break is, and how many breaks per day are taken.
  • Staff on break will immediately begin attending to their needs. Nb. Staff will always finish their current job before starting their break.
= Other changes
  • Arcade Cabinets have had their sound turned down
  • Larger clone size with Tools and Cheats enabled.
  • Main menu: 'Terms and Conditions' moved to Options menu.
  • Main menu: Added 'Other Introversion Games' link.
  • Tooltip added to Analytics in Options menu.
= BUG Fixes
  • Fixed: Dog Handlers would be completely paralised if injured, and there was no Medical Ward
  • Crash when loading with mods which define a custom room.
  • Family Rooms no longer erroneously display the cell quality too high warning.
= Update 11f HotFix
  • Guards whose needs are not being met were beating up the prisoners. This can still happen, but it should happen much more rarely now.
  • Extras | Map Settings dialog will now allow Staff Needs to be enabled if you already have enabled everything else.

    Nb. Can be disabled through Main Menu -> Options -> Game -> Zoom to mouse.
= Modding System (continued)
  • 'Infinite' mod loading The game now supports many more simultanious graphical mods than before It achieves this by gradually increasing the size of the graphics tileset, until your graphics card itself hits its limit In general users should find they can now activate a great deal more mods before any problems occur In addition, when the limit is reached you will now receive a warning/error message. (Previously it just started misbehaving)
  • Mods with spritesheets larger than 1024x1024 are now supported
  • Lua World Scripts:
    • Each mod can now have a data/world.lua script file, which should contain both Init() and Update( timePassed ) functions.

Update 6 + NEW IV Games (29 April 2016)  

Enjoy a new method to prioritise jobs and get to grips with weather systems and flooding. We’ve also continued with our performance work so it should run even smoother than a Baby’s bottom.

Full Change List

= Seasons and Weather
  • The game will now move through the seasons, with the outdoor temperature varying based on the time of year.
  • Various weather patterns can occur during the game, varying based on the current season.
    • Overcast
    • Rain
    • Torrential rain (Special event, rare)
    • Snow and frost
    • Heatwave (special event, rare)
  • Prisoners needs will be affected by the weather when they are outdoors. Getting rained on will spike their comfort, clothing and warmth needs.
  • Prisoners left outside in extremely cold conditions (for example in an outdoor solitary confinement cage) can now die of exposure.
  • Weather is DISABLED by default in all prisons, and can be enabled when creating a new map. Alternatively, use the new "Map Settings" screen in the Extras menu.
= Map Settings

You can now adjust the settings of your prison from a new screen called "Map Settings", found in the Extras menu. This screen lets you enable certain options that may not have been enabled (or even available) when you first created the map.
Nb. You can enable these options, but you cannot disable them once enabled.

Available options:

  • Enable Gangs
  • Enable Events
  • Enable Weather

= Job Prioritisation
  • You can now mark any job as a high priority. Simple hold control and either left click or left drag a selection to mark jobs. Available workers (who aren't already on a high priority job) will stop what they are doing and be assigned to the high priority job.
  • If no workers are available, high priority jobs will take precedence when the workers become available. A small icon in the lower right of a visible job shows if it is marked as a high priority job.
  • You can remove the high priority marking on jobs by holding control and either right clicking or dragging a selection.
  • Hovering over an in progress job will now highlight the entity working on it, showing a red line leading to the worker responsible for the job.
  • Pressing F while highlighting an in progress job will cause the camera to follow the working entity and keep the highlight active.
= Performance Work (continued)

Further performance gains were made this month through several different approaches to optimisation.

  • More systems moved to overlap with Render().
  • Optimisations to the visible object list builder.
  • Singly linked lists mostly replaced with arrays (FastList).
  • Avoid copying of containers where possible.
  • NeedSystem optimised.

= Bug Fixes

Temperature and lightmap system corruption bug fixed.

  • 0010618: [Gameplay] Temperature next to fire is in the negatives
  • 0010625: [Gameplay] Temperature drops instantly even in areas that should be producing heat

Update 5 (24 Mar 2016)  

You spoke, we listened. After a month of tweaking, tuning, tightening and teasing we have managed to stuff even more frames into every unforgiving second.  We've made significant performance gains so everyone should enjoy a smoother experience, but bear with us - we've got another month of speed updates to keep us busy over Easter.

Following our temperature work last month, Gary has updated the utilities mode to have a new hot water system and if you watch the vid we reveal all about Secret 3D Mode...

Full Change List

= Performance optimisations

We focussed on performance this month, and achieved a speed boost of at least 50%. This work is ongoing.

  • Now defaulting to the VS2015 build, with the old VS2008 build still available for Safe mode (Prison Architect Safe Mode.exe). This gives a good speed improvement over the VS2008 version.
  • Asynchronous job search system. Instead of synchronously looking for a job, workers, guards, prisoners, doctors now place a request for a new job in a queue. This queue is processed during render phase of the game loop so shouldn't take up any time during the main game loop.
  • Speed up rendering of the Feed Prisoners Objective. This was particularly slow when there were a lot of hungry prisoners.
  • Rebuild the indoor/outdoor shadow mask only when a cell changes its material or indoor/outdoor status.
= Thermodynamics (continued)
  • New pipe type in the utilities view: Hot water pipes These operate on a seperate layer to the existing pipes, and can be overlaid without conflict.
  • New utility: Hot water boiler Requires a large pipe connection of cold water, and a direct electrical connection You can run hot water pipes from this boiler in any direction. Nb. Water will lose heat the further it gets from the boiler.
  • All radiators now require a hot water connection to function
  • Showers can take cold water or hot water. When supplied with hot water, showers will also reduce a prisoner's Warmth need When supplied only with cold water will apply a Frigid effect, which acts as a kind of short-term surpression while also spiking their Warmth and comfort needs.
- 3d mode has been discovered.

This update we have improved 3d mode with new shapes, new shaders operating on all objects, and better wall geometry. 3d mode remains very experimental.

Known bug: The mouse position is wrong when using graphics/Supersampling.
Known bug: Long pauses caused by geometry changing, eg wall construction/demolition

  • Thermodynamic map to use 16 bit number type to represent the temperature instead of 8 bit. This fixes a bug with fire showing negative temperatures.
  • 0010610: [Graphics] entire screen is black and white boxes

Update 4 (4 Mar 2016)  

This month we've returned to our boffin-like roots and implemented a thermodynamic model. When the sun sets over the outer fence and the shadow of the sniper grows longer over the exercise yard, the temperature will begin to drop. Heat sources like the kitchen and radiators will keep things warm for a while, but the cold will start creeping through those thin cell walls.

Next comes Quick Build. Stolen straight from the console build comes the ability to stamp down whole cells and offices, This should make things a whole lot quicker and a bit less "grindy".

We've also packaged up some of the coolest prisons we could find so if you don't use steam, or your connection drops you still have something to play with. Along the same lines you can now filter the most popular steam prisons in game and tinker with the most popular penetentiaries on the workshop.

  • The game now models the ambient temperature of the world, and it's effect on your prisoners.
  • The outdoor temperature will vary during the day, and turn cold at night
  • The temperature of your indoor areas will be affected by this. Indoor areas near doors and windows will lose heat fast.
  • Certain existing objects generate lots of heat : Cookers (when in use), power stations, water pumps.
    • New toolbar button under Logistics : Temperature. Visualises the temperature of all areas of your prison
    • Prisoners now have a Warmth need. This need increases when they are cold.
    • They will protest if cold for too long, and eventually cause trouble.
    • If prisoners are too hot for too long (for example working in a hot kitchen) they will develop a status effect "Overheating".
      This makes them more likely to cause trouble
    • New item : Radiator. Build these around your prison to warm up the indoors when required.
= Quick Build menu
  • The old "Clone" toolbar item has been replaced with a new "Quick Build" menu, with more options.
  • You can now pick from a set of template rooms, and stamp them dowm in your prison.
  • All neccesary foundations will be built (if required), and the area will be cleared of walls and objects.
  • Then your workmen will build all the walls and objects required.
  • The room type will be automatically assigned.
  • You can rotate a quick build room using R or middle mouse click.
    Available quick build rooms:
    • Basic Cell
    • Solitary Cell
    • Luxury Cell
    • Shared Cell
    • Office
  • Nb. Clone is now available in the Quick Build menu and no longer needs to be researched.
= New prison sharing options
  • A new option in the Extras menu 'Most Popular Prisons' lets you view the most popular Steam Workshop prisons.
    You can choose to view the most popular over the last week/month/year/all time.
    Play the prison instantly by clicking Play.
  • We are now bundling 10 of the best community made prisons with all versions of the game.
    These are designed for times when you have no internet connection, or are not running the Steam build (so no workshop access)
  • You can now attach a Phone Tap to the Secure vistation booths added in Update 3. This will give you more intelligence on contraband, escapes etc.
= New Translations

Ukranian, Bulgarian, Traditional Chinese

Update 3 (27 Jan 2016)  

There's nothing more likely to stop you in your tracks than the sound of a sniper bullet screaming a few meters from your head. That'll be the warning shot, fired from the sniper in the tower, to stop an escape in it's tracks. Installing guard towers will certainly increase the security of your prison, but it won't do much for the psychological well-being of your prisoners - how would you feel if a bloke with a gun was watching you all day?

Want more tyranny? You can dehuminise visitation by building glass booths and phones. Prevent the hand-holding and all that business - prevents the drugs being smuggled too. Your prison, your rules.....

Full Change List

= Guard Towers + Snipers

You can now build guard towers around your prison for an extra level of security, intimidation, and force.

  • New entity type : Snipers
    • Hired from the staff menu.
    • These guys will equip themselves with a scoped sniper rifle from the armoury, if you have one.
    • They will then take turns manning the guard towers you have built.
  • Snipers will project 'Suppression' to all prisoners within their line of sight.
  • Rules of engagement
    • When snipers see trouble occuring, they will fire warning shots.
    • If three warning shots are ignored, they will shoot to kill.
    • If you have enabled "Freefire" they will always shoot to kill, without warning.
    • They will also shoot to kill if they see an escaping prisoner already outside the prison secure zone.

= Secure Visitation Booths

You can now build secure visitation booths in your visitation room if you choose, instead of the usual tables. A secure visitation booth has a glass panel that seperates the inmate from the family member, and they use a phone to talk.

  • No contraband can be imported through a totally secure visitation room
  • However the inmates family needs will not be satisfied nearly as well
  • Nb. There must be a complete seperation of visitors and inmates for a room to be considered secure.

= Female Names-in-the-game

If you are a Name in the Game customer, you can now update your bio and create a female prisoner if you wish. Go to to do this.

Merry Christmas; thanks for an incredible 2015 and all the best for 2016 from Mark, Chris and the rest of the Introversion Software team.

Full Change List

= Women's Prisons

You can now choose the gender of your prisoners in the "New Prison" screen. Female prisoners have different needs and behave differently than male prisoners.

Some female prisoners are mothers of young babies (less than two years old) and are entitled to look after their baby during their stay in your prison. This requires some new facilities - often called "MBUs (Mother and Baby Units)"
Family Cell
A new type of cell for mothers with babies only. Similar to a normal cell, but also requires a Cot and an integrated Shower. Nb these cells will never be assigned to female prisoners without babies.

A shared room for all mothers to live in, typically isolated from the rest of the prison. Mothers will spend much of their time in this room with their babies. Requires cots and play mats for the babies.

Mothers will eat their meals in this room, so it also requires a serving table, benches etc. Your kitchens will be assigned to cook meals for the nurseries as if they were canteens.

= Modding API (continued)
  • Added world and world cell data variables to the scripting API. This includes getting the size of the world, time index, etc. Setting these variables, however, is currently unsupported.
  • A new interface scripting API has been included as well. Mods can now add, remove, and change buttons in the BiographyWindow (shown when you select a non-prisoner object in the world), with callbacks to it's script.
  • Modding in escape mode has also been improved by allowing player interaction on scripted objects. A callback to the script is given when the player is close to an object and interacts with it.

- General performance enhancements, especially to laundry system.

- New Translations: Danish, Dutch, Hungarian, Thai

- Bug Fixes

  • Needs.txt not loaded in correct order when using mods
  • 0010162: [Gameplay] Surrendering in escape mode causes insane amounts of rep points / surrendering doesn't work
  • 0010309: [Control & User Interface] [Prison Architect] Crash when opening confidential informant window

Update 1 (13 Nov 2015)  

We're back!
Mark and Chris talk about their feelings, before taking a look at update 1.
Tweaks to escape mode, fine grain control over prisoner intake and most importantly multiple occupancy cells and BUNK BEDS!

Full Change List

= 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

No inmates will be brought to your prison
Inmates will be brought into your prison when available, until your available capacity is full
You set the total number of prisoners desired, and the Intake system works to fill that number
You choose the number of prisoners to bring in each day (The old method)
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.

    • 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%
