Undungeon is an action role-playing experience that brings back the spirit of old school action/RPGs wrapped in modern design. Restore the order in all dimensions, influence and determine the fate of the worlds, create and decide what will happen in the new Multiverse.

Several multidimensional versions of Earth were suddenly merged together, shattering one another in a cataclysmic event known as the Great Shift. This event damaged the fabric of time and space itself, seemingly beyond reconstruction. You, a Herald, will join a secret interdimensional organization — Herald's Undercover Bay, or simply H.U.B., created by Dharma to remedy the aftermath of the catastrophe.
