If you are okay with trading life in a vacuum with life under pressure: Barotrauma [0]
> Barotrauma is a 2D co-op survival horror submarine simulator, inspired by games like FTL: Faster Than Light, Rimworld, Dwarf Fortress and Space Station 13. It’s a Sci-Fi game that combines ragdoll physics and alien sea monsters with teamwork and existential fear.
You have roles in your submarines, such as a medic, mechanic, engineer, captain. Everyone can do the same things, but some are better than others at different things.
If you have time, you can build your own submarine. The game also has a good amount of mods available.
