Subnautica 2 Wiki
40 pagesSubnautica 2 is the underwater survival sequel from Unknown Worlds, set on an all-new alien ocean world. You crash, you dive, you scavenge and build, and you survive a sea full of beautiful and terrifying creatures, now with up to four-player co-op. It is in Early Access, so the world is growing fast, and this wiki tracks the biomes, creatures, vehicles, and systems as they land.
How Subnautica 2 Plays
The loop is the Subnautica loop, refined: explore, scan, craft, build, go deeper. You gather resources from the seabed, scan creatures and wrecks for blueprints, craft tools and vehicles, and build bases as forward camps while you push into darker, higher-pressure depths. Combat is mostly about avoidance and escape, not fighting, so reading creatures and managing oxygen and pressure is the real challenge.
Biomes and Depth
The ocean is layered by depth, and each biome sits in its own pressure band, from the bright, open Sparse Plains near the surface down to the volcanic Thermal Spires past a kilometer deep. Going deeper means better resources and bigger threats, gated by the gear and vehicles you have unlocked. Four biomes shipped at Early Access launch, with more on the roadmap.
Creatures and Leviathans
Subnautica is famous for its leviathans, the colossal apex creatures that make you think twice about every open stretch of water, and the sequel delivers. The Early Access build has 51 creature archetypes across predator, carnivore, herbivore, and passive tiers, headlined by the Collector and the Void leviathans. Our creature pages cover where each one lurks and how to survive it.
Vehicles, DNA, and Co-op
Three systems define a run. Vehicles like the customizable Tadpole submersible extend your reach and depth, with the returning Prawn Suit announced for the Early Access 1.1 update. The new DNA evolution system and its Biomods let you alter your genetics with a bio-sampler to withstand extreme depths. And co-op lets up to four players share the ocean, splitting scanning, building, and the terror of the deep.
A Note on Early Access
Subnautica 2 is actively in development, so creatures, biomes, vehicles, and story chapters are still being added. We keep this wiki to what is confirmed in the current build and update it as each patch lands, rather than repeating leaks. For setup and co-op, see our Subnautica 2 guides.

Subnautica 2 FAQ
Is Subnautica 2 out yet?
Subnautica 2 launched into Early Access on May 14, 2026, on PC (Steam and Epic) and Xbox Series X|S, including Game Pass on day one. A PlayStation version was not part of the Early Access launch. The game is playable now and content is being added throughout Early Access.
Does Subnautica 2 have co-op multiplayer?
Yes. Subnautica 2 supports up to four-player co-op with cross-platform play, so you can explore, build bases, and take on leviathans together. It is still a full single-player experience too, and nothing requires co-op to progress.
How many biomes are in Subnautica 2?
Four named biomes shipped at the Early Access launch: Sparse Plains, Graveyard, Plateaus, and Thermal Spires, layered by depth from the surface down past 1,200 meters. Unknown Worlds has committed to adding more biomes throughout Early Access.
What leviathans are in Subnautica 2?
The Early Access build includes 51 creature archetypes, with two named leviathans so far: the Collector, a huge sonar-broadcasting cephalopod predator, and the Void, a scythe-finned open-water hunter that attacks in groups. More leviathans are planned on the roadmap.
Is the Prawn Suit in Subnautica 2?
Not yet. The Prawn Suit is confirmed to return, but it is part of the announced Early Access 1.1 update and is not in the live build. The current build's main vehicle is the Tadpole, a cheap, heavily customizable single-seat submersible with swappable chassis and upgrade modules.
What vehicles are in Subnautica 2 right now?
The Tadpole is the main vehicle in the current Early Access build: a single-seat submersible you unlock by scanning three fragments, then reconfigure with chassis swaps (like the fast Scout Ray or the cargo Haul) and upgrade modules for depth, stealth, efficiency, charging, and armor. The returning Prawn Suit is announced for the Early Access 1.1 update.
What is the DNA evolution system in Subnautica 2?
It is a new survival mechanic where you use a bio-sampler to alter your own genetic code, adapting your body to survive extreme depths and hostile conditions. It is a feature that was cut from the original game and brought back for the sequel.
Does Subnautica 2 have microtransactions?
No. Unknown Worlds has formally committed to no microtransactions, no season passes, no battle passes, and no subscriptions. You buy the game and get the full Early Access experience and its updates.
