About Subnautica
Subnautica strands you on an alien ocean planet after your spaceship crashes, and the only way home is to survive beneath the waves. You start with a lifepod, a fabricator, and the ocean all around you, gathering resources while learning which creatures are curious, dangerous, or both. As you dive deeper, you build bases, submarines, and diving equipment that let you explore biomes ranging from sunlit coral reefs to pitch-black trenches teeming with leviathans. The game has no combat focus — instead, survival means managing oxygen, food, water, and your own fear of the deep. Its story unfolds through radio signals, wrecked ships, and ancient alien ruins, guiding you toward a way off the planet. The sense of discovery, atmosphere, and genuine dread of the unknown depths make it one of the most memorable survival games ever made.

It is a survival game with strong atmosphere and some genuinely tense moments in deep, dark waters, but it is not a traditional horror game.
