About Subnautica 2
Subnautica 2 is an underwater survival adventure set on a new alien world. After ongoing conflict drives you from home, Alterra offers you a new life. You and your fellow Pioneers travel aboard the colony ship CICADA, but something goes wrong. Stranded, you must survive against near-insurmountable odds; the future of humanity on the planet is in your hands.
Explore the planet
Explore vibrant biomes, scan and study the planet’s biodiversity, and encounter life ranging from small creatures to towering Leviathans. Long-forgotten ruins and the mysteries beneath the surface may reveal why the ship’s AI insists that the mission continue. Every dive can bring discoveries as well as danger.
Adapt to survive
Use the Tadpole submersible to travel through the biomes, and design and customize bases to return to when you venture beyond the safety of shallow water. Tools, equipment, vehicles and upgrades help you push farther and uncover the secrets of the world.
Play alone or together
Subnautica 2 is designed as a single-player experience, with optional online co-op for up to three friends. You can choose from four pre-designed characters and work together to explore the ruins and adapt to a planet that may not want you there.
