Subnautica is an open world survival game created by developer Unknown Worlds Entertainment. Released earlier this year, it was an accident that I stumbled upon this game from a post on Reddit. It was a free pc download so I decided to give it a try and I was surprised it’s a well-polished game. The story starts when a ship crash lands in an unknown planet composed mostly of water. Alone, hungry and scared, your task is to build objects using the fabricator and find a way back home.
