OxygenAdds the need to have oxygen tanks behind your back. Moving around the planet also consumes oxygen, since not all planets are habitable. You can also breathe underwater! However, you have a limited amount of oxygen, don't forget to replenish the supply of oxygen cylinder on the ship!
Probably compatible with OopsAllFlooded but you'll find two oxygen canisters. One is from the Oxygen mod (OxyBoost) and one is from the OopsAllFlooded mod (Oxy-Canister). The working one is from this mod and is called OxyBoost.
Check the config file, there are plenty of settings :)
