How it plays
Up to four players share one ocean, splitting the work between gathering, base building and pushing into deeper, scarier water.
A 2026 update added proximity voice chat and the ability to revive each other.
It is in early access on PC and Xbox, so the story is unfinished.
Each player needs a copy, and PC and Xbox players can dive together.
