Immerse yourself in a new adventure with Subnautica 2, an open-water survival game from the creators of the Subnautica series. Play alone or with friends as you explore alluring biomes and discover fascinating creatures. Craft vehicles, tools, and bases to survive this mysterious alien world.

Whether playing with friends or alone, players will craft tools, build custom bases, and navigate the depths of this immersive, alien world as they forge their own survival stories.

Subnautica 2 will officially introduce multiplayer co-op, offering a new way to experience the adventure together. Up to four players will be able to explore the ocean’s vast environments together, and collaborate to craft tools, build bases, and face the challenges of a planet teeming with both beauty and danger.

Expanding on what fans loved about the previous games in the series, Subnautica 2 will deepen the experience with new biomes, from towering underwater cliffs to lush coral fields, each filled with unique creatures and hidden mysteries. As players dive deeper, they will uncover the secrets at the heart of the planet.

Unknown Worlds released the first Early Access update for Subnautica 2, expanding key gameplay systems and improving the early-game experience based on player feedback.

The update arrives shortly after the game surpassed 5 million cumulative sales in early June following its Early Access launch across PC (Steam, Epic Games Store), and Xbox Series X|S on May 14.

This first update focuses on refining core systems, improving co-op quality of life, and giving players more ways to explore, survive, and customize their progression.

Expanded Biomods and New Biolabs
A major focus of the update is the Biomod system, which allows players to temporarily borrow traits from nearby creatures to enhance their abilities. The update adds two new Biolabs in the Coral Gardens and Axum Ruins, increasing the number of unlockable Biomods from four to six. Players can also unlock additional passive Biomod slots by scanning targets with the Bioscanner.

Improved Co-op Audio and PDA Databank Controls
The update also improves how audio logs work in co-op. Audio logs will no longer play automatically when collected and can instead be played manually through the PDA Databank, the in-game archive that expands as players scan creatures and collect records throughout the world. This change helps prevent audio logs from automatically playing for other players during co-op sessions, creating a smoother shared experience.

Exploration, Survival, and Basebuilding Updates
Exploration and survival have also been updated. Wrecks now include additional routes and oxygen-based puzzles, while players can now sprint outside the water, including on the surface and inside bases. Base-building improvements include better placement for the Tadpole Dock and Fabricator, along with a new dedicated storage structure. Additional improvements have also been made across rendering, creature behavior, and the user interface.

“With this update, we focused on refining the early-game experience and core systems,” said Fernando Melo, Executive Producer at Unknown Worlds. “We’ll continue shaping the world of Subnautica 2 together with our players throughout Early Access.”
