"Subwater Survival Simulator is an open world, underwater exploration and adventure game.
After crash landing on an alien ocean world, called Subnautica, the only way to go is down. Subnautica's oceans range from sun drenched shallow coral reefs to treacherous deep-sea trenches. Manage your oxygen supply as you explore Kelp Forests, plateaus, reefs, and winding cave systems. The water teems with life: Some of it helpful, much of it harmful.
After waking up in your Life Pod, the clock is ticking to find water, food, and to develop the equipment you need to explore. Collect resources from the ocean around you. Craft knives, lights, diving gear and personal water craft. Venture deeper and further form to find rarer resources, allowing you to craft more advanced items.
