Subnautica 2 takes place on an all-new underwater alien world beyond Planet 4546B, and you can play solo or team up with as many as three friends—four players total. Its Early Access began May 14, 2026, so features and performance may change as development continues.
Is Subnautica 2 set on a new planet?
Yes. Unknown Worlds describes the sequel as an underwater survival adventure on an all-new alien world. The series is moving beyond Planet 4546B, the setting of the earlier games; official announcements do not identify the new planet by name. Unknown Worlds’ current game page describes the new setting, while its 2024 announcement first said the story would travel beyond 4546B.
The new world is the setting for exploration and survival, with base building and tool crafting among the features listed on the official game page. The page does not establish that every planned feature is final.
Does Subnautica 2 have multiplayer?
Yes, but co-op is optional: you can explore alone or play with up to three friends, for a maximum of four players. That makes multiplayer a way to share the survival adventure, not a requirement to play the game.

Can you play with friends on other platforms?

Subnautica 2 is still in development. The Xbox listing warns that it is a work in progress and may contain bugs, features that are still being developed, and performance issues. Early Access descriptions should not be read as promises about the finished feature set, final performance, or a full-release date; the sources cited here do not give a full-release date.
The practical choice is whether you would rather explore alone or share the experience with friends. The game supports both approaches, but its evolving state means the experience may change during Early Access.
