Below Zero is an underwater adventure game set on an alien ocean world. It is a new chapter
in the Subnautica universe, and is currently in development by Unknown Worlds.
Return to planet 4546B
Dive into a freezing underwater adventure. Below Zero is set in an arctic region of planet
4546B. As a scientist posted to a research station on the planet's surface, you are tasked with
studying alien artifacts...
Craft, Survive, Research
The Vesper space station orbits high above you, sending supplies, and receiving samples you
send up. When disaster strikes the research station, you must improvise to survive: Scavenge
for resources, build shelter, and craft equipment.
Explore New Biomes
Swim beneath the blue-lit, arching growth of Twisty Bridges. Navigate treacherous ice floes on
the ocean surface. Clamber up snow covered peaks, and venture into icy caves. Below Zero
presents entirely new environments for you to explore.
Encounter New Creatures
Discover new lifeforms in the icy depths of 4546B. Swim through giant Titan Holefish, escape
from aggressive Brute Sharks, and visit adorable Pengwings. Some residents of the frozen
ocean will help you, and some might try to harm you.
An Ocean of Intrigue
Who were the aliens who came here before? Why were they on this planet? Can you trust your
commanders? Below Zero extends the story of the Subnautica universe, diving deep into the
mystery introduced in the original game.
