Below Zero is an underwater adventure game set on an alien ocean world. This is a new chapter in the Subnautica universe, developed by Unknown Worlds.
Return to Planet 4546B
Immerse yourself in a new expedition in sub-zero temperatures in an arctic region of Planet 4546B. Arriving with little more than your wits and some survival gear, you set out to investigate what happened to your sister…
Discover the Truth
Alterra left in a hurry after a mysterious incident. Abandoned research stations are scattered throughout the region. What happened to the scientists who lived and worked here? Records, items and databases scattered throughout the wreckage paint a new picture of the incident. With limited resources, you must improvise to survive on your own.
Discover Unexplored Biomes
Swim under the blue arches of the Twisted Bridges. Be mesmerized by the glittering giant crystals of the Crystal Caves. Climb snow-capped peaks and venture into the frozen caves of the Glacial Basin. Maneuver between erupting thermal vents to discover ancient alien artifacts. Below Zero features all-new environments for you to survive, study, and explore.
Build Habitats and Vehicles
Survive the harsh climate by building sprawling habitats, scavenging for resources, and crafting equipment. Travel across the snow-covered tundra on a Snowfox hovercraft. Travel through enchanting and dangerous biomes in your modular Seatruck.
Research Alien Life Forms
There is something unknown lurking behind every rock. Swim past the gigantic Titan Holefish, meet the terrifying Dark Leviathan, and visit the adorable Pinglins. But keep your eyes open. Not all creatures in this strange world are friendly.
Survive Freezing Temperatures
Dive in, the water is warm. The sub-zero temperatures of this Arctic region are a new threat. New climatic conditions cover terrestrial habitats. Make warm clothes, drink hot coffee and warm up near the Thermal Lilies to avoid freezing.
An Ocean of Intrigue
What really happened to your sister? Who were the aliens that were here before you? Why did they come to this planet? Can the truth serve as comfort in grief? Below Zero expands the story of the Subnautica universe, delving deeper into the mystery presented in the original game.
