Subnautica 2 Release Date: Early Access & 1.0 Launch Info
Subnautica 2 released in Early Access on May 14, 2026 for PC and Xbox Series X|S. The 1.0 full release is expected 2-3 years later â roughly 2028-2029 â with a higher price and all 10 planned story chapters.
Last updated: September 5, 2026
Early Access Launch: May 14, 2026
Subnautica 2, developed by Unknown Worlds Entertainment and published by Krafton, entered Early Access on May 14, 2026. It is available on:
- PC â Steam, Epic Games Store, and Microsoft Store (included with Game Pass PC)
- Xbox Series X|S â via the Game Preview program
The sequel moves the series to a new alien ocean moon called Proteus, runs on Unreal Engine 5, and adds optional 4-player online co-op â a first for the series. It is a standalone story: no knowledge of the original game is required, though Alterra and familiar crafting return. PlayStation owners will have to wait â see our PS5 release date breakdown for why.
Early Access here means the real thing: the world of Proteus, the full survival loop, base building, vehicles, and co-op are all playable today, but the map, creature roster, and story are still growing. Saves carry forward through updates, and Unknown Worlds has a long track record of shipping its Early Access promises â the original Subnautica followed the same path to a celebrated 1.0.
When Is the 1.0 Full Release?
Unknown Worlds has said Early Access is expected to last 2-3 years. Counting from May 2026, that places the 1.0 launch in a 2028-2029 window. No exact date has been announced, and the studio has been clear that the timeline depends on player feedback and development progress rather than a fixed marketing calendar.
Buy now if you want the cheaper price, want to shape development through feedback, and can tolerate an unfinished story (1 of 10 chapters). Wait for 1.0 if you want the complete story, all biomes, and the large submarine â or if you only own a PS5.
Early Access Update Roadmap
Two named updates lead the roadmap, followed by larger expansions. Neither EA 1.1 nor EA 1.2 has a confirmed release date yet.
| Update | Focus | Highlights |
|---|---|---|
| EA 1.1 | QoL | Biomods improvements and more passive slots, expanded Blight encounters, enhanced wreck gameplay, vehicle docking & fabrication upgrades, PDA Databank expansion, priority voice logs, Sprint ability, storage cache system. Full details in our EA 1.1 update guide. |
| EA 1.2 | Co-op | Proximity voice chat, animated emotes, player trading, player revive, HUD signal improvements, base builder tool upgrades, pinned recipes, more customization. See the EA 1.2 update guide. |
| Later expansions | Major | New regions and biomes, new creatures and Leviathans, new resources and tools, the large multi-seat submarine (the Cyclops equivalent), and the next story chapters. |
Pricing: Buy Early, Pay Less
Unknown Worlds has confirmed that the price increases after the 1.0 full release. Early Access buyers keep the game forever at the lower price and receive every update â including 1.0 â at no extra cost.
Just as notable is what the game does not have: no microtransactions, no battle passes, no season passes, no loot boxes, and no subscriptions. It is a single purchase, exactly like the original.
If you are unsure about buying an unfinished game, Game Pass PC includes the Early Access version â a zero-risk way to try Proteus before the price goes up.
Story Chapters: 1 Now, 10 at 1.0
Subnautica 2 delivers its story in chapters. Early Access launched with chapter 1, and 10 chapters are planned for the 1.0 release, rolling out through major updates during Early Access.
What is already in the game is a full survival loop: the Lifepod start with 45 seconds of oxygen, the NOA terminal mission chain, Adaptation Chambers and Biomods, base building, the Tadpole submersible, and 4-player co-op. New chapters expand the map and the mystery rather than replacing existing saves. If you are just starting out, our Beginner Tips guide covers the critical first hour.
