The Bottom Line: This is the kind of mechanic that seems obvious after you know it, but the game sure as hell won’t tell you upfront. I learned most of this the hard way — by drowning, starving, or getting eaten. The systems in Subnautica 2 are deep but fair. Once you understand how they work, survival stops being a struggle and starts being a strategy. And that’s when the real fun begins.
