Mosh has gone in search of her lost daughter and must battle to the center of the Earth to unearth clues to her whereabouts. The Slag, enemies made of living metal, inhabit the areas above and below the surface and will do anything to stop her.

Navigate and conquer beautiful hand-drawn worlds, do battle with unique bosses, interact with quirky characters, and use a variety of collectibles gathered from battle to reach your goal. Help Mosh decide how to interact with her companions, the Forgebeasts. Different stats and abilities will unlock depending on the bonds you forge and will help you crush your heavy metal foes as you journey further into the Earth.
