Below Zero is the next chapter of Subnautica, the underwater survival open world set on an alien ocean planet.

FEATURES
UNCOVER THE TRUTH - Who were the aliens who came here before? Why were they on this planet? What really happened to your sister? And will exposing the truth give some closure to your loss?
SURVIVE THE COLD - The freezing temperatures of this arctic region pose a new challenge. Craft a toasty cold suit, sip on piping hot coffee, and warm up next to Thermal Lilies to stave off the chill.
CRAFT YOUR WAY - Survive the harsh climate by constructing extensive habitats, scavenging for resources, and crafting equipment. Blast across the snowy tundra on a Snowfox hoverbike. Cruise through enchanting and perilous biomes in your modular Seatruck.
EXPLORE THE PLANET - Swim beneath the blue-lit, arching expanses of Twisty Bridges, be mesmerized by the Crystal Caverns, venture into the icy caves of Glacial Basin or maneuver between erupting Thermal Vents to discover ancient alien artifacts.
MEET NEW CREATURES - Something undiscovered lurks around every corner. Swim through the giant Titan Holefish, encounter the haunting Shadow Leviathan, and visit the adorable Pengwings. Keep your wits about you. Not all creatures in this strange world are friendly.
