Subnautica Below Zero
You have crash-landed on an alien ocean world, and the only way to go is
down. Subnautica's oceans range from sun drenched shallow coral reefs
to treacherous deep-sea trenches, lava fields, and bio-luminescent
underwater rivers. Manage your oxygen supply as you explore kelp
forests, plateaus, reefs, and winding cave systems. The water teems with
life: Some of it helpful, much of it harmful.
After crash landing in your Life Pod, the clock is ticking to find water, food, and to develop the equipment you need to explore. Collect resources from the ocean around you. Craft knives, lights, diving gear, and personal water craft. Venture deeper and further form to find rarer resources, allowing you to craft more advanced items.
Build bases on the sea floor. Choose layouts and components, and manage hull-integrity as depth and pressure increase. Use your base to store resources, park vehicles, and replenish oxygen supplies as you explore the vast ocean.
