On The Skeld, O2 is a small room towards the map's top-right corner, below Weapons. It features three short tasks and one of the number pads to resolve Oxygen Depletion. It appears that a plant is inside the box with the number pad, possibly helping produce oxygen to the ship. To the right of O2 is a camera, which also captures the entrance to Navigation.
On Polus, O2 takes up the space of three rooms, two medium-sized and one small. It is located above Boiler Room. The top-left room contains the first stage of the Upload Data task, the Monitor Tree task, and a vent. The main room contains the Empty Garbage and Fix Wiring tasks, and the small room contains the Fill Canisters task.

Main article: Oxygen Depletion
On The Skeld, Impostors can Sabotage O2, starting the Oxygen Depletion sabotage. To solve this Sabotage, living players must insert a code written on a yellow sticky note to the right side of the number pads in O2 and Admin within 30 seconds. The code in O2 is identical to the code in Admin.
Although Polus contains an O2 room, there is no Oxygen Depletion Sabotage.
Main article: Door Sabotage
On Polus, Impostors can Sabotage the doors of O2, locking living players inside. However, living players can open doors by flipping four disabled switches. As with other locations on Polus, these doors do not affect ghosts.
- O2 was originally named "LifeSupp," short for "Life Support."
- Plants can be found in both O2 locations, implying that the plants help produce oxygen for the Crewmates.
- Although O2 does not appear on MIRA HQ, a similar location, Greenhouse, does appear instead, which serves a similar purpose.
- On the Polus map, players can hear birds in the tree in O2 if they listen closely.
