Below Zero is an underwater adventure set in an alien oceanic world. Welcome a brand-new chapter in the Subnautica universe, developed by the studio Unknown Worlds. If you want to experience subnautica below zero on your Mac, prepare for an unforgettable deep-sea journey across a frozen alien planet.

Return to Planet 4546B

Embark on an underwater expedition in the frigid arctic region of planet 4546B. Armed with nothing but your wits and a modest set of survival equipment, you must investigate the mysterious events surrounding your sister's disappearance on this remote and hostile world...

Uncover the Truth

After a mysterious incident, Alterra hastily abandoned the planet. The entire region is littered with deserted research stations. What happened to the scientists who once lived and worked here? Journals, personal belongings, and data repositories scattered among the wreckage allow you to piece together an entirely different perspective on what truly occurred. With severely limited resources at your disposal, you will need to improvise and adapt in order to survive.

Discover Uncharted Biomes

Swim beneath the shimmering blue arches of the Twisty Bridges. Marvel at the enormous sparkling crystals found deep within the Crystal Caves. Scale snow-covered peaks and explore the frozen caverns of glaciers. Navigate between erupting thermal vents to uncover ancient alien artifacts. In subnautica: below zero, an entirely new world of survival, exploration, and wandering awaits you at every turn.

Build Habitats and Vehicles

Construct spacious habitats, gather essential resources, and craft specialized equipment to endure the harsh and unforgiving climate. Race across the snow-blanketed tundra on the Snowfox hoverbike. Traverse the captivating yet perilous biomes aboard the modular Seatruck submarine, which you can customize to suit your exploration needs.

Encounter Alien Life Forms

The unknown will greet you at every step of your journey. Swim through the colossal Ventgarden titan, seek out the elusive Shadow Leviathan, and visit the adorable Penglings in their natural habitat. However, remain vigilant at all times. Not every creature inhabiting this wondrous and strange world is friendly toward you.

Survive Sub-Zero Temperatures

Jump right in — the water is warm. The sub-zero temperatures in this arctic region present an entirely new and dangerous threat to your survival. Above the water's surface, you will face challenging new weather conditions. Put on a warm and cozy cold suit, pour yourself a steaming cup of hot coffee, and warm up beside the thermal lilies to fend off the biting cold.

An Ocean of Intrigue

What really happened to your sister? Who were the aliens that discovered this place long before you arrived? Why did they choose to live on this particular planet? Can we truly find solace from grief in the truth? The storyline of Below Zero expands the lore of the Subnautica universe, diving even deeper into the compelling mystery of the original game.
