Subnautica: Below Zero — Dive into the Frozen Depths of an Alien Planet
Subnautica: Below Zero is an underwater adventure set on an alien ocean world. It is a new chapter in the Subnautica universe developed by Unknown Worlds. Return to Planet 4546B two years after the original game, now in the Arctic region, and survive the sub-zero temperatures while uncovering the truth behind a deadly cover-up.
Key Features
- All-new frigid environment: Explore the glowing Twisty Bridges, dazzling Crystal Caverns, snow-covered peaks, and glacial basins. Navigate between erupting thermal vents and search for ancient alien artifacts.
- Survival and crafting: Build pressurised habitats and vehicles, scavenge resources, and craft equipment to endure the harsh climate. Zip across frozen tundras on the Snowfox hoverbike, and traverse dangerous biomes in the modular Seatruck.
- Alien lifeforms to study: Encounter giant Titan Holefish, the lurking Shadow Leviathan, and adorable Pengwings. Stay alert — not all creatures are friendly in this unfamiliar world.
- Cold-weather survival: Sub-zero Arctic temperatures pose new threats. Craft warming suits, drink steaming hot coffee, and huddle near Thermal Lilies to stay alive.
- A conspiracy of the deep: Investigate what happened to your sister. Explore abandoned research stations, and piece together the truth from scattered logs, items, and data storage to uncover the purpose of the aliens who visited this planet.
