Platform status

Is Subnautica 2 Coming to Nintendo Switch?

Quick answer for Nintendo players, plus an honest take on whether the original Switch can even run this game.

Not announced. Unknown Worlds has not listed any Nintendo platform for Subnautica 2. The original Switch hardware would also struggle to run it (the first Subnautica already ran below 30 FPS on Switch). Switch 2 is more capable on paper, but again, no announcement.

Where each Nintendo platform stands

Switch (original)
No, and unlikely. The original Subnautica only barely ran on Switch at sub-30 FPS. Subnautica 2 targets newer hardware.
Switch 2
Not announced. Technically possible, but Unknown Worlds is leading with Xbox / PC and has not commented on a port.
Confirmed today
Steam, Epic, Xbox Series X|S, Xbox on PC, ROG Xbox Ally, Game Pass Ultimate, PC Game Pass.
