Subnautica – Steam key

Subnautica, developed by Unknown Worlds Entertainment, is a first-person underwater survival and exploration game. After your ship crashes on a planet entirely covered in water, you find yourself in a lifepod with a fabricator and nothing else. You then have to dive: gather resources, build tools, a diving suit, underwater vehicles and then a habitable base, all while managing oxygen, hunger and thirst. The descent into the depths is the real progression of the game and the darkness there becomes more and more oppressive.

What awaits you

• Underwater biomes — glowing reefs, kelp forests, caves, volcanic zones and abysses, each with its own fauna and resources.
• Base building — modules, corridors, aquariums, greenhouses and managing structural integrity according to depth.
• Vehicles to build — from the small single-seat submarine to the large habitable submersible to explore deeper.
• Scanning and discovery — analyse fauna and wrecks to unlock new blueprints.
