Long ago, four heroes defeated the evil sorceress Belcorra Havereaux at the cost of one of their lives. The surviving heroes founded a town nearby in his name: Otari.

Belcorra's base, The Gauntlight, was recently activated and reanimated the town's dead. Three heroes rose to the occasion to stop the threat. It is now up to this new band of heroes to delve beneath the Gauntlight and cease threat the Abomination Vaults pose.  

They are the Vaultbusters.
