A 90 average flying under the radar. Worth knowing about before everyone else finds it. Survival is the whole game — scarce resources, bad odds, and every small win feeling huge. The story is the main course; the multiplayer is the reason it's still installed years later.

About this game

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.

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.
