About Subnautica 2

Subnautica 2 is an underwater survival adventure from Unknown Worlds, set on an all-new alien world. You play as a Pioneer from the colony ship CICADA. After the mission goes awry, you are stranded, and must explore, craft and build a life in the depths as the ship’s AI insists the work should continue.

You can play alone or in online co-op with up to three friends, designing custom bases, piloting the Tadpole submersible and studying the planet’s creatures, from the smallest wildlife to towering Leviathans.
