Brave the icy depths of Planet 4546B in Subnautica: Below Zero, a thrilling underwater exploration game. Set two years after the original Subnautica, you'll return to this alien world to uncover a deadly cover-up amidst the abandoned research stations scattered across the arctic region. With little more than your wits and some survival equipment, you must investigate what happened to your sister and the scientists who once called this place home.

Survive the harsh climate by constructing habitats and vehicles, researching alien lifeforms, and scavenging for resources. Craft essential equipment as you navigate uncharted biomes; build a sprawling base and a high-tech Snowfox hoverbike. Pilot the modular Seatruck through shimmering kelp forests and navigate the crushing depths of the arctic abyss. Survival is a constant challenge. Beware: below-zero temperatures pose a new threat, requiring you to craft cold suits and seek warmth against the chill.

Subnautica: Below Zero extends the immersive story of the Subnautica universe, diving deeper into mysteries introduced in the original game. Discover the truth behind Alterra's hasty departure, the secrets of the aliens who came before, and the chilling events that grip Planet 4546B. Will you plunge into the icy depths of 4546B and unearth its buried secrets?
