In the history of survival-crafting games, few titles are as iconic as Subnautica. Even over a decade after its early access debut, nothing else captures such an alien underwater world so vividly. Now, you can carry that deep-sea adventure in your pocket with Subnautica available for purchase on mobile!
When the deep-space colony ship Aurora crashes unexpectedly on planet 4546B, you find yourself stranded alone on a world almost entirely covered by water. Your only companions are a moderately helpful AI and a futuristic fabricator that can produce any survival gear—provided you gather the necessary materials.
Your mission? Survive. The planet's wildlife ranges from harmless guppies to fearsome Leviathan-class predators lurking in the ocean depths. You'll need to craft tools, collect resources, and uncover blueprints to create everything from survival knives and upgraded flippers to your very own personal submarine.

Gone Fishing
Subnautica includes the original survival mode alongside freedom and creative modes for more relaxed gameplay. Content-rich, it features numerous undersea biomes to explore, tools and vehicles to discover, and a mysterious storyline revealing that 4546B might not be as deserted as it initially appears.
Subnautica comes highly recommended, though with its stunning underwater visuals, you'll probably want to use a gaming phone for optimal experience. For entertainment that makes even the longest flights feel brief, it's hard to top this adventure!
