Subnautica: Below Zero

Subnautica: Below Zero is Unknown Worlds Entertainment's follow-up to their landmark underwater survival game — a standalone expansion set on a different region of Planet 4546B, one covered in arctic tundra and frozen ocean biomes that complement the original game's warm tropical depths with cold, claustrophobic menace. Playing as Robin Ayou, a researcher searching for her missing sister, the game's story is more character-driven and dialogue-heavy than the original's, thanks in part to Sam — an alien entity who provides companionship and narrative momentum. The underwater environments are extraordinarily atmospheric: bioluminescent creature clusters beneath frozen ice shelves, crystal caverns of alien minerals, and deep-ocean trenches of crushing darkness all contribute to Below Zero's distinctive identity. New tools like the Prawn Suit's grappling arm and the Snowfox hovercraft expand traversal options. A worthy companion to one of the best survival games ever made.
