Prisoners' Quarters

The Prisoners' Quarters is the only level one biome in the game. It is the starting point of every run.

A run-down stone dungeon with mossy bricks and prison cells visible in the background — most with broken bars. Torches line the walls. Decay is a reality for this prison, as any authority has long met their doom or fled. Some cells still house what prisoners were (un)lucky enough to have survived this long.

Starting Area
A glass chute drips water and muck from the ceiling. Beheaded prisoners are found underneath, either dropped from the chute or executed on the nearby chopping block. The Giant's skeleton rests in the back.

In the next room over, large glass flasks for unlocked items hang from chains. The Scribe is nearby, guarding the door to the Daily Run. Below the bottles is a large glass tube for adjusting the difficulty with Boss Stem Cells. Below the tube is the door to the Tailor's room. The door to the right leads to the starting weapons.

Access and exit
The Prisoner's Quarters is the starting area of the run. After a completed or failed run the player will start back here. The entrance to the Daily Run is also located here. It's possible to exit the Daily Run back into the Prisoners' Quarters.

There are three exits, the Promenade of the Condemned, the Toxic Sewers which requires the and the Dilapidated Arboretum (from The Bad Seed DLC) which requires the.

Specialist's Showroom
The Specialist's Showroom is a special shop that always appears in the Prisoners' Quarters once unlocked from the Collector for 150 cells. Access is locked by a button in front of the door, and a teleporter is always found at its end.

In the table below, you will find which enemies are present in the Prisoners' Quarters depending on difficulty level. For each enemy, any common, uncommon, rare or legendary blueprints they carry are indicated. When applicable, the minimum difficulty level for blueprint acquisition is specified in brackets.

Malaise

 * A prisoner managed to escape from their cell and left a messy message. The legible parts of the writing read: "Don't want... contaminated... out of here... see you again. I hope. The 'Malaise'. ...not infected. won't die"
 * An unfinished message on the wall of an empty cell reads: "Why... filling the prison with innoc".

prisoners

 * A prisoner can be found hanged inside their cell in the Prisoners' Quarters, the Promenade of the Condemned, or the Ramparts.


 * A prisoner locked in a cell can be encountered here or in the Promenade of the Condemned. The prisoner first calls out to the Beheaded, only to realize who they are speaking to. They jest about the fact that they are on "the right side of the door for once", before speaking to himself about how "they" didn't mess around. Kicking the door afterwards yields no response.
 * A prisoner locked in a flooded cell can be found here or the Ramparts. They get the Beheaded's attention and complain about the water. He then exclaims that he felt something touch his leg, and then calls for help. Sounds of their murder by some creature are heard, before they are rendered unresponsive.
 * Tom the Mushroomologist, a drug dealer, dealt psychotropic mushrooms to the other prisoners. He was able to turn a pretty good profit, but no signs of his current whereabouts exist.

other rooms

 * A scientist with a Headcrab on his head can be found as a Half-Life Reference. Behind it is a secret room with the Blueprint of the HEV Outfit and the . After these two are turned in to the collector, this room stops spawning.

Royal gardener

 * A lore room requiring the to access contains the corpse of the Royal Gardener with a Letter from Castaing (The Concierge) to him prior to the events of the game. It contains numerous wall spikes and a  found on the body of the Gardener.
