Subnautica delivers one of the most immersive survival experiences ever created. After your spacecraft crashes onto an unexplored ocean planet, you must survive using only the resources available beneath the waves.

Unlike traditional survival games, nearly the entire adventure takes place underwater. Every dive into the deep ocean introduces new discoveries, valuable resources, and increasingly dangerous lifeforms. Players must carefully manage oxygen, food, water, and equipment while exploring one of gaming's most beautiful and mysterious environments.

The game combines exploration, crafting, base building, storytelling, and survival mechanics into an unforgettable adventure that rewards curiosity and careful planning.

Story

Following the destruction of your spaceship, the Aurora, you awaken inside an emergency Life Pod floating on the vast ocean of Planet 4546B. Alone and surrounded by endless water, your mission is simple—stay alive.

As you explore deeper into the ocean, mysterious radio transmissions, abandoned alien facilities, and clues left behind by previous explorers gradually reveal the truth behind the planet's deadly ecosystem. Every discovery brings you closer to uncovering one of science fiction gaming's most memorable stories.
