Subnautica is an underwater adventure and survival action-adventure game set on an alien ocean planet in an open world environment and played from a first-person perspective. A massive, open world full of wonder and peril awaits you!
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 as Ryley Robinson, the lone survivor of the crashed spacecraft known as The Aurora, the clock is ticking to find water, food, and to develop the equipment you need to explore the remote ocean planet known as 4546B. Collect resources from the ocean around you. Craft diving gear, lights, habitat modules, and submersibles. Venture deeper and further 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.
