Youve crash-landed on an alien water planet, and the only way forward is down. Subnauticas seas feature everything from sun-drenched coral reefs to treacherously deep sea trenches, lava fields and luminescent rivers. Make sure you have enough oxygen as you explore kelp forests, plateaus, reefs and winding caves. The water teems with life: Some helpful, but most harmful.

After you crash land in your Liv Pod, the clock starts ticking to find water, food and to develop the equipment you will need to explore. Collect resources from the sea around you. Create knives, light sources, diving equipment and hydroelectric plants. Explore deeper to find rare resources so you can develop more advanced items.
