In Dishonored, Corvo Attano must escape Coldridge after being unjustly imprisoned for the assassination of Empress Jessamine Kaldwin by Hiram Burrows, her usurper. In The Brigmore Witches, Daud must infiltrate the prison to release Lizzy Stride, the leader of the Dead Eels gang, from custody.
The prison is connected to Dunwall Tower by a bridge, leading to the prison's main gate. Coldridge has the security feature of two automated gates, controlled by levers in two different rooms. A single door leads out to the execution yard, which is fortified by guarded walkways and fences. Beyond the control area is the prison yard, and in addition there are four cell blocks, A-D. A, C, and D are located to the right of the main yard, and cell block B is to the left. Each cell block consists of three levels with a guard booth and a lockable stairway between cell blocks C and D. An interrogation room sits in the back of the building.
Thanks to Sokolov technology, the prison has security features, including alarms, loudspeakers, and later on, an Arc Pylon. Should an alarm sound, the doors to the cell blocks will all close and lock. Individual cell doors are controlled by a machine in the cell control room, which is located off the walkway and above the yard.
Accessible to Corvo is cell block B (where Corvo is held at the beginning of the first mission along with three Bottle Street gang members), the interrogation room, stocks (which can be viewed through Corvo's cell window, but not visited) and the drawbridge connecting Coldridge to Dunwall Tower.
The Brigmore WitchesEdit
In The Brigmore Witches, security has been tightened following Corvo's escape, but the outer door still is not fixed. The section in which Corvo was held, cell block B, is blocked off and dark, but some new locations can be found, such as cell blocks A, C, and D. In addition, Daud will have now access to the stocks and execution yard.
Hatters, survivors, and an aristocrat are added as prisoners, and an Overseer music box plays over the speakers outside the building. The interrogation room is also drastically changed due to the interrogation of Melina, a Brigmore witch.
- While the execution yard can be seen from Corvo's cell in the mission Dishonored, it can only be explored during Daud's mission A Stay of Execution for Lizzy but had several design changes. Additional structures were added against the outer wall as well as pipes to offer an alternate way in and out of the prison. Moreover the door to the yard, which can only be seen from outside the prison (it appears as a plain wall from the inside), was also altered, and a crawl space was added above to sneak in and out of the yard.
- The door to the yard can be opened like any other door, but cannot be passed through because of the wall on the other side.
