A sandbox survival/horror
game developed by Unknown Worlds Entertainment. Subnautica is
unique in that the alien world it is set upon is an ocean planet, so the
game takes place almost entirely underwater. The player must collect fish for
food, scrap and minerals to build tools, vehicles, and habitats, while avoiding hungry wildlife, in order to cure the Kharrar disease and escape Planet 4546B.
A critical part of this experience is that the player character has only a survival knife to use as a weapon, robbing him of the ability to fight back against the aforementioned hungry wildlife. Subnautica wouldn't be as
cool and scary as it is without this feature.
