Subnautica 2 FAQ
The questions everyone's asking about Subnautica 2 — release date, multiplayer, platforms, and what's in Early Access right now.
When is Subnautica 2 coming out?
+
Subnautica 2 entered Steam Early Access in 2025 from Unknown Worlds. A full 1.0 release has not been dated — Unknown Worlds historically spends 12–24 months in Early Access before 1.0, so expect ongoing content updates through 2026 with a full launch likely in 2026–2027.
Is Subnautica 2 multiplayer?
+
Yes. Subnautica 2 supports co-op for up to 4 players, a first for the series. You can play solo with the same content, host a private session, or join a friend. There is no PvP.
Is Subnautica 2 cross-platform / crossplay?
+
At Early Access launch Subnautica 2 is PC-only (Steam). Crossplay across platforms is not available yet because consoles have not launched. Unknown Worlds has indicated console parity is a goal once consoles ship.
Will Subnautica 2 be on PS5 and Xbox Series X|S?
+
Console versions for PS5 and Xbox Series X|S are planned, but they will not arrive until after the PC Early Access period. No firm release window has been confirmed.
How much does Subnautica 2 cost?
+
Subnautica 2 launched in Early Access at the standard Unknown Worlds price point ($29.99 USD / similar regional pricing on Steam). The price is expected to rise at 1.0 release, as is typical for Steam Early Access titles.
Where does Subnautica 2 take place?
+
Subnautica 2 is set on the ocean planet Proteus, a new world separate from 4546B (the original Subnautica) and Sector Zero (Below Zero). New biomes include the Coral Gardens, Sparse Plains, Karakorum spires, and the Void.

Is there a Subnautica 2 roadmap?
+
