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 has rolled out the second Early Access (Steam, Epic Games Store, Xbox Series X|S) update for Subnautica 2, introducing new features designed to strengthen communication and teamwork in co-op. Alongside the update, the studio announced a USD 100,000 donation to ocean cleanup non-profit The Ocean Cleanup.

This update focuses on strengthening the cooperative play experience, with new systems for how players communicate and support one another underwater.

Proximity Voice Chat

Proximity voice chat is the centerpiece of the update, applying distance-based spatial audio to player communication. Nearby teammates sound louder and more directional, while voices fade naturally as players drift apart.

New Revive System

A new revive system has also been added. When a player’s health is depleted, they enter a downed state instead of dying immediately and can continue exploring if a teammate revives them within a limited window. The change raises the tension of deep-sea survival while making cooperation more meaningful.

Communication and Teamwork Improvements

Communication and teamwork have improved in other ways as well. An emote system lets players signal one another without voice, and players can now access a teammate’s inventory directly to hand over resources. Other improvements have been applied across cooperative play, including throwable location tags, the signal system, and base-building convenience.

Supporting Ocean Conservation

The Ocean Cleanup is a non-profit organization that develops and scales technologies to remove plastic pollution from the world’s oceans. Unknown Worlds previously donated a portion of proceeds from the original Subnautica to The Ocean Cleanup on World Environment Day in 2019, and has continued to support ocean conservation efforts since.

“Subnautica began with a love for the ocean, and it means a great deal to continue the conservation work we started with the original game through this donation to The Ocean Cleanup,” said Fernando Melo, Executive Producer at Unknown Worlds. “We will keep doing our part to protect the ocean we have spent so long bringing to life.”
