Pilot an armored mining rig through a living crystal mine. Choose connected routes, dodge crystalline enemies and let your weapons fire while you steer, dash and unleash your Pulse. Recover hardware, refit your rig in the Workshop and return with a different arsenal. The Black Iron Campaign leads through eight district seals toward the World Engine finale, with browser saves for unlocks and suspended expeditions.
