Currently Nitrogen works like this. Nitrogen adds up beside your "Depth meter" These "Nitrogen points" will raise faster the deeper down you are. Being in a cyclops seamoth or seabase will not bring your nitrogen points up OR down. When you have nitrogen points you will have to accend cautiosly because raising to fast will result in death. Currently the nitrogen system is a "cheat" and must be activated via the console. typingNitrogen in the console enables/disables this cheat. It is unknown if the devs are going to do more work with this current feature or not.
