How co-op works
Up to four divers share an Early Access world, exploring an alien ocean, gathering resources, monitoring oxygen, building habitats, and piloting vehicles. The crew can divide scouting, resource runs, and construction or travel together through story objectives, but no task requires multiple players.
About this game
Subnautica 2 drops you onto a new alien ocean planet where survival depends on resourcefulness and teamwork. You can explore solo or join up to three friends in four-player online co-op, venturing into uncharted underwater biomes, gathering materials, and piecing together the planet's secrets. The cooperative structure transforms every dive into a shared challenge where one player scouts ahead while another manages oxygen supplies or defends against hostile creatures.

Building custom bases becomes a group project as you coordinate construction, assign roles, and pool resources to create safe havens beneath the waves. Crafting tools, vehicles, and equipment requires careful communication, especially when deep expeditions stretch your supplies thin. The alien environment constantly tests your ability to adapt, making every session a mix of tense exploration and collaborative problem-solving.
Online co-op supports cross-platform play, so friends on different systems can dive together. Each expedition rewards coordination and planning, whether you're mapping dangerous trenches, harvesting rare materials, or simply keeping each other alive when the ocean turns hostile.
