Crater Edge

The Void is an area that borders the entire map of Subnautica. It currently has no use, and is not canonical to the story.

The Void is the end of the map and has a bottom at 3000 meters depth, past this there is another, seemingly infinite drop.

Multiple adult Ghost Leviathans live in the Void, where they act as a deterrent for wandering players going outside of the playable area.
