極地監獄 (English: Operation Locker) 是一个出现在战地4多人游戏中的一个地图。该地图是在中国昆仑山的监狱。它侧重于近身步兵战斗，设有一个圆形监狱的地方，其主要Levolution是中间的监狱塔倒塌。
[Conquest Large] A large area contains stacked racks and containers that can provide cover. An upper area to the south connects the indoor path from the nearby deployment to an outer area near Mess Hall.
This wide room is fairly porous, with few of the walls offering solid cover.
Two of the north hallways have natural gas lines in the ceiling that can be burst, incinerating anyone passing through.
A freezer area below has lighting that can be temporarily disabled, leaving those below in cold mist.
The central tower holds .50 Cal machine guns that point towards either of the upper indoor entrances. Metal floor grating prevents passage between the upper and lower levels, except through the north stairwell. The stairwell also leads outdoors and provides a long lane to the panopticon from outside.
Explosives can knock down two additional side entrances beside each upper indoor passage. The supporting walls of the panopticon can also be destroyed, causing its collapse, moving the control point and opening a path between floors.
It may be possible to reach the outer rings of cells by stacking equipment or using a "human ladder", using the dark areas to great advantage. However, players with the XM25 or the IRNV and FLIR scopes can easily spot such intruders.
An M82A3 MID appears outdoors in front of the hillside.
Fighting is more confined in this section that features short hallways, numerous corners, and wall remnants that can conceal prone players or traps.
Vacant holding cells in this area may contain explosive tanks. An explosion in any single cell may set off the tank, exposing all four cells at once and killing anyone inside. Numerous staircases and ledges provide quick vertical travel.
[Conquest Large] The generators in the lower level offer some cover from attackers above, and some good hiding places for beacons. Natural gas pipes also line the upper ceiling, giving players below an easy way to eliminate enemies above.
The Panopticon 作为炸弹生成的地点.所有的M-COM都是在室内，虽然整个地图是开放给所有玩家。
The tower inside the circular room at the center of the map can be collapsed by destroying several walls on the lower and upper level of the tower. Doing so will cause the tower to crumble and bring down a section of the floor, creating a ramp from the lower level to the upper level.
The snowstorm outside the map will also intensify and calm throughout the duration of the match, effecting visibility and sight lines along the outside path.
