Subnautica

Subnautica is an open world, underwater exploration and adventure game currently under construction at Unknown Worlds, the independent developer behind Natural Selection 2. It aims to elicit a feeling of experiencing the unknown, of not knowing how far, and how deep you can go. Using various submarine vehicles, you will be able to explore diverse environments filled with resources, creatures, plants, threats, and natural wonders. The world will take you from lush coral reefs teeming with life, to volcanic lava zones that could threaten your vessel, and your survival.
