Below Zero is an underwater adventure game set on an alien ocean
world. It is a new chapter in the Subnautica universe, and is
developed by Unknown Worlds.

*Return to planet 4546B*

Submerge yourself in an all-new, sub-zero expedition in an
arctic region of Planet 4546B. Arriving with little more than your
wits and some survival equipment, you set out to investigate what
happened to your sister…

*Uncover the truth*

Alterra left in a hurry after a mysterious incident. Abandoned
research stations dot the region. What happened to the scientists
who lived and worked here? Logs, items, and databanks scattered
among the debris paint a new picture of the incident. With limited
resources, you must improvise to survive on your own.

*Discover uncharted biomes*

Swim beneath the blue-lit, arching expanses of Twisty Bridges.
Become mesmerized by the glittering, mammoth crystals of the
Crystal Caverns. Clamber up snow covered peaks and venture into the
icy caves of Glacial Basin. Maneuver between erupting Thermal Vents
to discover ancient alien artifacts. Below Zero presents entirely
new environments for you to survive, study, and explore.

*Construct habitats and vehicles*

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.

*Research alien lifeforms*

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.

*Survive the chilly temperatures*

Jump in, the water’s warm. The below zero temperatures of this
arctic region pose a new threat. New weather conditions blanket
above-ground habitats. Craft a toasty cold suit, sip on piping hot
coffee, and warm up next to Thermal Lilies to stave off the
chill.

*An ocean of intrigue*

What really happened to your sister? Who were the aliens who
came here before? Why were they on this planet? Can we find solace
from grief in truth? Below Zero extends the story of the Subnautica
universe, diving deep into the mystery introduced in the original
game.

*About the development team*

that traces its roots back to the 2002 Half-Life mod Natural

Subnautica. The team is scattered around the globe, from the United
