What is Subnautica 2?
Subnautica 2 is an underwater survival adventure from Unknown Worlds, set on an all-new alien world. The Xbox Store listing describes you as a Pioneer from the colony ship CICADA. After the mission goes awry, you are stranded, and the ship’s AI insists the work should continue. You explore, craft, build custom bases and pilot the Tadpole submersible, studying the planet’s creatures from the smallest wildlife to towering Leviathans.
You can play alone or in online co-op with up to three friends. Four pre-designed characters are available in Game Preview, with more characters and customisation options due as development continues.
When did Subnautica 2 come out on Xbox?

Which Xbox platforms is Subnautica 2 on, and is it Play Anywhere?
It’s on Xbox Series X|S only, and it’s optimised for Xbox Series X|S. It is an Xbox Play Anywhere title, so a purchase on Xbox also covers Windows PC via the Xbox app. Xbox Wire also listed Xbox on PC and the ROG Xbox Ally at launch.
