HARRY'S MOD: THE SUBNAUTICA™ app for iPhone and iPad
This game is an open world, underwater exploration and adventure game. You are in an alien ocean world, the only way to go is down. These oceans range from sun drenched shallow coral reefs to treacherous deep-sea trenches. Explore plateaus, reefs, and winding cave systems. The water teems with life: Some of it helpful, much of it harmful. Collect resources from the ocean around you. Use the ecosystem to help you. Lure and distract a threatening creature with a fresh fish, or simply swim as fast as you can to avoid gnashing jaws of roaming predators.
