Dive into the depths of an extraterrestrial underwater world full of wonders and dangers. Build equipment, sail submarines, escape predators and terraform the world. Explore colorful coral reefs, volcanoes, cave systems and much more. But try to stay alive!
After a crash landing on an unknown water planet, the only way to get to the depths is by land. Subnautica's oceans range from sun-drenched coral reefs to deceptive deep-sea trenches. Watch out for your oxygen as you dive through seaweed forests, overgrown plains, reefs and caves. Underwater is teeming with creatures, some useful, but many dangerous.
