Subnautica 2 entered early access on May 14 2026 for $29.99 on Steam, the Epic Games Store, Xbox Series X/S, and Xbox on PC, and it is included with Game Pass on day one. The headline change for the series is online cooperative play for up to four players, alongside full solo play.
What is new in Subnautica 2?
Subnautica 2 takes the underwater survival formula and adds multiplayer for the first time in the franchise. You explore a new alien ocean on the planet Luca, arriving via the CICADA colony ship. The launch build ships with a working core loop of exploration, scanning, crafting, base building, and survival, plus confirmed features like the Collector Leviathan, the Tadpole Submersible, DNA modification, sculptural base building, and ocean currents that physically push you off your route.
Cooperative play is fully optional. You can dive solo exactly as in the original, or bring up to three friends along. There is no split screen and no couch play, but cross platform multiplayer connects players across Steam, Epic, and Xbox.
When did it launch and where can you play it?
Early access began May 14 2026 at 08:00 Pacific for $29.99, and the price is set to rise once the game reaches its full 1.0 release. The original Subnautica spent about four years in early access, and the developers estimate this sequel will stay in early access for roughly two to three years, which places the finished version somewhere between 2027 and 2028.
Worth noting for anyone with friends on other systems: there is no PlayStation 5 or Nintendo Switch version, so the game is currently a PC and Xbox affair. Unknown Worlds has said it is focused on polishing the current platforms first.
Why was the road to launch so chaotic?
The path here was anything but smooth. Publisher Krafton fired Unknown Worlds CEO Ted Gill and the studio's cofounders in 2025, just weeks before a planned launch, triggering a public legal battle. A court later ordered Gill reinstated, and both sides ultimately confirmed the May 2026 early access date despite the friction.
The good news for players is that development never stopped during the dispute. The team kept writing story chapters, designing creatures, and building biomes, and the studio has reaffirmed its no microtransactions, no battle pass philosophy. For survival fans, it is the most wishlisted game on Steam finally arriving in playable form.
