Atmosphere generator

Introducing the Atmosphere Generator: instead of just having bases empty of water by default and able to make oxygen with just a bit of power simply existing, have an upgradeable piece on the ceiling and/or exterior which generates atmosphere/air to push out the water and generate oxygen for some power with an actual cost per tick! Have upgrades for energy efficiency or for extra power to push out water at deeper depths (or for bigger bases)! Maybe make the base have more durability (ability to resist damage/defence, not hull points) with certain amounts of pressure generated at different depths to counter exterior pressure (maybe make the base creak ominously if the pressure isnt sufficient).

I like the idea of bigger bases and deeper bases having more overhead by necessity. Seems more realistic!

yeah, but i think it would better fit into a new more realistic suvival game mode because it deviates from how previous Subnautica games work.

On the other hand it offers a lot of interesting options that can add to immersion: https://subnautica2.nolt.io/10069
