Subnautica: Below Zero

Subnautica: Below Zero is an underwater adventure set in an alien ocean on Planet 4546B. In an arctic region, you investigate what happened to your sister and uncover the truth behind a mysterious incident that caused Alterra to leave in a hurry. With limited resources and little more than survival equipment, you must improvise to survive.

Investigate the incident

Abandoned research stations are scattered across the region. Logs, items and databanks among the debris reveal clues about the incident and the scientists who lived and worked there. The story also explores who the aliens that came to the planet were, why they came, and whether truth can bring solace from grief. Below Zero continues the mystery introduced in the original Subnautica.

Explore the biomes

You can swim beneath the blue-lit arches of Twisty Bridges, explore the giant crystals of the Crystal Caverns, climb snow-covered peaks and enter the icy caves of Glacial Basin. You can also navigate erupting Thermal Vents to find ancient alien artifacts. The region's environments are places to survive, study and explore.

Build and travel

Construct habitats, scavenge resources and craft equipment to survive the harsh climate. Ride a Snowfox hoverbike across the snowy tundra, or travel through dangerous biomes in the modular Seatruck.

Encounter alien life

The ocean is home to creatures including the giant Titan Holefish, the Shadow Leviathan and Pengwings. Some creatures are not friendly.

Face the cold

Arctic temperatures and changing weather threaten you, including above-ground habitats. Craft a cold suit, drink hot coffee or warm yourself beside Thermal Lilies to stave off the chill.
