About Subnautica

Subnautica is Unknown Worlds' open-world survival game set almost entirely underwater on an alien ocean planet, where crash survivors must scavenge, craft and build increasingly advanced vehicles and bases to survive and eventually escape. Its slow-building sense of dread and wonder made it one of the most acclaimed survival games of its decade.
