Subnautica is a survival adventure game set on an alien, completely oceanic planet. A vast open world full of stunning sights, secrets, and deadly threats awaits you, where every journey into the depths of the ocean is a fight for survival. After the escape pod breaks, the only way to escape is to go deeper and deeper under the surface of the water. Explore diverse biomes – from shallow, sunlit coral reefs to dark ocean trenches to lava fields and underwater rivers illuminated by bioluminescence. Manage your oxygen supply, avoid predators, and explore an unknown ecosystem where not everything wants to help you. Collect, craft, and survive Harvest resources from the environment, craft tools, diving equipment, knives, light sources, and underwater vehicles. The deeper you go, the more valuable materials you discover, allowing you to create more and more advanced equipment. Build underwater bases Design and expand your own bases on the ocean floor. Keep them tight as the pressure builds up, use them to store resources, park vehicles, and replenish oxygen supplies during long expeditions. Uncover the mystery of the planet Learn the secrets of an alien civilization, investigate the causes of a catastrophe and a mysterious disease decimating marine life. Explore the structures scattered across the ocean and see if there is a chance to return safely from this planet. Survive in the food chain Use the environment to your advantage – distract predators, lure them with bait, or run away before they become a deadly threat. Extreme Depths Build and modify the powerful PRAWN suit with mining drills, torpedo tubes, and grippers to explore the ocean's most dangerous areas. The horror of the night and underground caverns After dark, the ocean becomes much more dangerous, and seemingly safe places turn into deadly traps. Also explore the vast cave systems hidden beneath the ocean floor, keeping an eye on oxygen and keeping a watchful eye on your surroundings. Subnautica is a unique blend of exploration, survival, and atmospheric storytelling, created by Unknown Worlds, that rewards curiosity, courage, and the ability to adapt to a merciless, alien world.
