The oceans of Subnautica range from shallow coral reefs to dangerous deep-water trenches, lava fields, and underwater rivers of bioluminescence. Manage your oxygen supply as you explore kelp forests, plateaus, reefs, and caves.

The ocean is teeming with life, wonderful sea creatures abound, but beware! Not all are friendly. Lure and distract a menacing creature with a fresh fish, or simply swim as fast as you can to avoid the jaws of predatory creatures.
