A ragtag band of gunslinging outlaws get their hands dirty in the greasy alleyways and whisky-soaked saloons of Alkenstar, the City of Smog. To get revenge on the mogul who destroyed them, the renegades will have to stick up an illicit bank, foil a crooked shieldmarshal, and escort a reclusive inventor to safety. All the while, countless rough-and-tumble rivals aim to waylay the party and seize the inventor's latest concoction: pyronite, an explosive substance with the potential to change the face of the world. In a city where the clockwork guards are literally as tough as brass, the antiheroes will need true grit to dole out overdue justice.
