Subnautica 2 is in Game Preview, and you can tell. I still dropped into the water and spent an evening following lights into the deep, nervous every time something large moved past. That sense of an ocean with real depth is the best thing here. It's unfinished, with rough edges and content still to arrive, so ranking it above finished games felt wrong. Come back when it leaves preview. If you're happy exploring an early build, there's plenty of water already, and co-op is optional if you'd rather share the panic.

Overview
About Subnautica 2
Subnautica 2 is an underwater survival adventure set on an all-new alien world, developed by Unknown Worlds. Play alone or with friends in 4-player co-op. Adapt to survive by building custom bases and crafting tools. Explore the unknown to uncover the mysteries hidden within the depths.
Story setup
The Alterra colony ship Cicada, bound for the desert world of Zezura, inexplicably diverts course and crash-lands on an uncharted ocean moon called Proteus. The world's extreme atmospheric pressure and heavy metal contamination means all human life will perish within months. To survive, the ship's AI uses "reprinting" technology to restore backed-up consciousness into new bodies, but the process causes severe memory loss. Decades after the original colonists vanish under mysterious circumstances, a new investigator is printed to uncover what happened to them and confront the secrets hidden beneath the alien ocean.
