The Crater is the area in which the main story of Subnautica takes place. The Crater and Sector Zero are the two major ecosystem centers known on Planet 4546B.
The area is the crater of a huge, long-dormant undersea volcano approximately three kilometers in height and two kilometers in diameter. After the volcano became dormant the crater was filled in by sediments and the once volatile volcano became the center of a diverse and thriving ecosystem.
