Copyright: subnautica
A game that plunges the player into a vast alien ocean after the terraforming vessel they were aboard succumbed to interference and plummeted into a nearby planet.
Made available during its early access stages, Subnautica focuses on deep underwater exploration and survival. Thalassophobes beware.
