Subnautica 2 Player Guides for Planet Proteus
Subnautica 2 takes place on the alien planet Proteus, where 40,000 Alterra colonists have gone missing. The game launched into Early Access on May 14, 2026 with single-player and up to 4-player co-op. Unlike previous games, Proteus has no in-game map — you navigate by compass, beacons, and landmarks. New systems include Biomods (genetic player upgrades), the Tadpole submersible, and Adaptations that let you survive hostile environments. Every guide here answers one real player question: find what you need, execute the plan, and get back to diving.
