Subnautica 2 now features a multiplayer co-op mode that supports up to four players with full cross-play between PC and Xbox consoles.
This addition transforms the series from a solitary survival experience into a social one. By allowing players to collaborate, the developers have addressed one of the most requested features from the community [4].
The game supports a maximum co-op limit of four players [1]. This means a single party can consist of one player and up to three friends playing simultaneously [1].
Cross-platform functionality is a core part of the experience. The game provides full crossplay support across PC (Steam) and Xbox Series X/S consoles [2, 3]. This ensures that hardware preferences do not prevent friends from playing together.
Accessing these features is handled through the game's interface. To join a co-op session in Subnautica 2, select Join Friends from the main menu, a Shacknews article author said [0].
Players can now divide tasks such as resource gathering, and base construction across their group. This collaborative approach changes how players navigate the dangers of the deep sea—a shift from the isolation of the first title.

The transition to a multiplayer model represents a significant pivot for the franchise. By implementing cross-play between Steam and Xbox, the developers are maximizing the potential player base and reducing friction for social entry. This move aligns the title with modern industry trends where survival games rely heavily on community-driven, cooperative gameplay to maintain long-term engagement.
