Understory is a fan-made sequel for the original game and boy is it a brilliant game. The game uses many of the same old mechanics but expands on the story considerably. Like the original game, players can enjoy an utterly peaceful run or a genocide playthrough.

The game follows the ending of the original, where the monsters return to the surface. However, most of the gameplay occurs underground. You follow the story of Nick, a boy who falls into the underground.

Once underground Nick discovers that not all monsters went to the surface. Several monsters remain in the underground due to their mistrust of humans. Nick must try to find his way back to the surface and convince the beasts to join him.
