Warhammer 40,000: Exterminatus

The most insidious and dangerous threat in the 41st millenium is one you cannot see. It is this thought that spawned the Inquisition, an organisation devoted to rooting out traitors, heretics, mutants and aliens that undermine Humanity. They scour the Imperium searching for threats without, and within. Immediately following the events of Warhammer 40,000: Damnation Cruise, Inquisitor Delius Alastor is dispoatched to investigate why a pair of dormanr Titans has gone undetected beneath the city of Carrion Gulf? Is Alastor capable of meeting what lurks beneath Carrion Gulf?
