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!
Dive Into a Vast Underwater World
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.

Scavenge, Craft, and Survive
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.
Construct Underwater Habitats
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.
Unravel the Mystery
Signs abound that something is not right. What caused you to crash? What is infecting the sea life? Who built the mysterious structures scattered around the ocean? Can you find a way to make it off the planet alive?
Disrupt the Food Chain
The ocean teems with life: Use the ecosystem to help you. Lure and distract a threatening creature with a fresh fish, or simply swim as fast as you can to avoid gnashing jaws of roaming predators. Be aware of the most extreme dangers, such as Crabsquids, Warpers, Mesmers, Bonesharks, Ampeels, Stalkers, Crashfish, and Leviathan-class lifeforms like the Reaper, Sea Dragon, and Ghost Leviathans.


Handle the Pressure
Build a Pressure Re-Active Waterproof Nanosuit (PRAWN Suit), and explore extreme depth and heat. Modify the suit with mining drills, torpedo launchers, propulsion cannons, grappling hooks, and more.
Fear the Night
As the sun goes down, the predators come out. The ocean is unforgiving of those caught unprepared in the darkness. Areas that are safe to explore during the day become treacherous at night, but also reveal a beauty that those who hide from the darkness will never see.
Dive Below the Ocean Floor
Cave systems wind below the sea bed, from dark claustrophobic passages to caverns lit by bio-luminescent life and burning-hot lava flows. Explore the world below the ocean floor, but watch your oxygen levels, and take care to avoid the threats lurking in the darkness.
Difficulty Modes
Upon beginning a new game, players are given an option between four difficulty modes:
- Survival mode: Manage health, hunger, thirst, and oxygen. Respawn with certain items removed from the inventory.
- Freedom mode: Similar to survival mode but without hunger and thirst.
- Hardcore mode: Includes permanent death. If the player dies, they do not respawn, and their save file is permanently deleted. No warnings of low oxygen levels.
- Creative mode: All depleting characteristics are removed. All blueprints are unlocked, and the player can craft without needing resources. Submersibles, a stasis rifle, a Seaglide, a mobile vehicle bay, and a propulsion cannon are provided without needing an energy source and are immune to crush depth.
