The Prison is the third main location in the Dead Ops Arcade, being playable from rounds nine to twelve. The Prison is an open area with freedom to walk without impairment. There is a catwalk that extends around the perimeter of the map, with two ramps that allow the player to walk up onto it. There is an area of the catwalk where the handrail is broken. Here, the player can jump off the side of the catwalk back onto the main floor, which is useful for making quick escapes. There is a dead body under the catwalk. The first time the player enters The Prison, they must complete a bonus challenge entitled 'Prison Break!'. This is a round consisting entirely of Prisoner Zombies. Prisoner zombies are introduced during these rounds. They behave exactly like regular zombies, but have increased health.
