About Subnautica: Below Zero
Subnautica: Below Zero is a single‑player underwater adventure set in the arctic north of Planet 4546B. You arrive with only basic survival gear and must explore frozen biomes, gather resources, and piece together the mystery of a missing sister and an abandoned research effort.
The game adds new creatures, environments, and vehicles while keeping the core loop of crafting, habitat building, and temperature management. It runs on Windows and macOS and supports full controller input, Steam Cloud, and other Steam features.
01 / THE GUIDE
Story and Setting
The narrative follows a new expedition to the icy region of Planet 4546B, where abandoned research stations hint at a hurried departure. Logs, items, and databanks scattered among the debris let you reconstruct what happened to the scientists and your sister.
Distinct biomes such as Twisty Bridges, Crystal Caverns, and Glacial Basin provide visual variety and clues about the incident that forced Alterra to leave the area.
- Read every log and databank you find; they often contain essential story details.
- Note environmental cues like weather changes that may indicate hidden locations.

Exploration
You can swim beneath blue‑lit arches, glide through crystal‑filled caverns, and climb snow‑covered peaks. Both underwater and surface areas are freely navigable, revealing alien artifacts and new fauna.
Surface travel includes traversing erupting Thermal Vents and venturing into icy caves, offering a mix of visual spectacle and hidden resources.
- Use natural lighting to spot points of interest from a distance.
- Watch your depth gauge when diving into deeper zones.

Construction and Vehicles
Survival depends on building habitats that can withstand sub‑zero temperatures. You craft cold suits, thermal gear, and other equipment to stay alive while gathering resources.
Transportation options include the Snowfox hoverbike for tundra travel and the modular Seatruck for navigating hazardous biomes, extending the range of exploration.
- Prioritize habitat insulation before venturing far from base.
- Construct a Snowfox early to reach distant surface points quickly.

Survival Mechanics
Cold is a new threat; you must craft a toasty cold suit, sip hot coffee, or warm near Thermal Lilies to avoid hypothermia. Weather can blanket above‑ground habitats, adding another layer of challenge.
The ecosystem includes both friendly and hostile creatures such as the Titan Holefish, Shadow Leviathan, and Pengwings, requiring careful navigation and occasional avoidance.
- Monitor your temperature meter regularly, especially when outside habitats.
- Carry a backup heat source in case weather changes unexpectedly.
