Oxygen

General Info
Oxygen is a resource shared amongst all players, displayed at the top of the screen via the Oxygen Bar. The game will notify players when the oxygen level has reached low and critically low levels, flashing orange and red respectively.

Oxygen depletes at a fixed rate as time passes. Oxygen can be added to the global supply by repairing oxygen generators and inserting oxygen canisters into oxygen stations. Oxygen can be removed from the global supply (outside of the constant depletion) by sabotaging oxygen generators and oxygen stations, or by failing to repair an oxygen generator.

When oxygen is critically low, all players (including personoids) will move at a slower walking pace and will clutch their necks as if they are struggling to breathe. If oxygen depletes fully, all residents will die immediately. Residents killed in this way will have their end-game status listed as suffocated.

Tips

 * Oxygen is effectively a timer that pressures residents to complete the level. It should be monitored at all times.
 * Sabotaging oxygen stations will show a small warning in orange text to all players, while sabotaging oxygen generators will show a large red warning
 * Oxygen will continue to deplete during the countdown after all keycards are inserted. Players can still be suffocated during this time.
 * While in the elevator, oxygen will deplete and restore a single increment repeatedly. This means that if you are one tick away from suffocation when players are teleported into the elevator, you can still be killed. This can also result in the 'low' and 'critically low' oxygen HUD warnings flashing back and forth repeatedly during the elevator ride

Oxygen Generators
There are Oxygen Generators on every map in the game. Generators require two players to fix, and require both players to execute a rhythm skillcheck until the repair bar fills completely. A successful repair will increase the global cap for oxygen in the level and add a fixed amount of oxygen to the supply. Similarly, failing the skillcheck or sabotaging the generator will lower the global cap for oxygen in the level and remove a fixed amount of oxygen from the supply.

Oxygen Stations
Oxygen Stations are wall-mounted oxygen units located on every map. Oxygen canisters can be used at these stations to add oxygen to the global supply When functional, they are lit by a bright blue screen. When sabotaged, the screen will instead show orange as well as a countdown timer. At the end of the countdown, the station will be usable again (and can be sabotaged again). Oxygen stations will be highlighted on your HUD when the global oxygen level is low.

Oxygen Canisters
Players may carry up to 3 oxygen canisters at a time, which can be used at Oxygen Stations. See items for more information on Oxygen Canisters.
