Underground



The Underground is the first layer below the surface. It starts at a depth of 0ft and can be recognized by its background which contain many small rocks. Unlike Dirt Walls this background stop players from hammering holes for daylight and building wood platforms at any place (if they don't join onto a nearby block). The music changes when the player goes a few feet deeper past the intersection of the rocky and rockless walls.

The Underground is home to more aggressive enemies than the surface, as well as more treasure.

If a player continues downwards, eventually they will reach the Cavern layer.
