Subnautica Below Zero

Subnautica: Below Zero is an underwater adventure game set on an alien ocean world. It is a new chapter in the Subnautica universe.

You 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.

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