The undead Corpse Fleet has appeared in orbit above the Gate of Twelve Suns, intent on seizing the ancient alien superweapon called the Stellar Degenerator. Massively outgunned, the heroes` only hope lies in infiltrating the fleet`s flagship and seizing control of the vessel`s bridge. Only then can the heroes set the ship to self-destruct and pilot it on a collision course with the superweapon. If successful, the heroes can destroy the Stellar Degenerator, but they`ll need to escape the destruction to live to tell the tale!
