Subnautica is an open world, underwater exploration and adventure game currently under construction at Unknown Worlds, the independent developer behind Natural Selection 2.
Dive Into a Vast Underwater World
After crash landing on an alien ocean world, 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.
Scavenge, Craft, and Survive
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.
Construct Underwater Habitats
Build bases on the sea floor. Choose layouts and components, and manage hull-integrity as depth and pressure increase. Use your base to store resources, park vehicles, and replenish oxygen supplies as you explore the vast ocean.
Disrupt the Food Chain
The ocean teems with life: 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.
Fear the Night
As the sun goes down, the predators come out. The ocean is unforgiving of those caught unawares in the darkness. Areas that are safe to explore during the day become treacherous at night, but also reveal a beauty that those who hide from the darkness will never see.
Shape the World
The Subnautica sea-floor is presented using a dynamic voxel terrain system. Dig caves to hide, store loot, or short-circuit cave systems. Impacts from vehicles, or even exploding creatures, will change the way the world looks.
Go Below The Deep
Cave systems wind below the sea bed, from dark claustrophobic passages to caverns lit by bio-luminescent life. Explore the world below the ocean floor, but watch your oxygen levels, and take care to avoid the threats lurking in the darkness.
