Jackie Estacado has become head of the Franchetti family, and has learned to suppress the Darkness , an ancient demonic force in his bloodline. Jackie is haunted by the memory of his murdered girlfriend, Jenny Romano . Jackie and his crew are attacked in a restaurant by a rival gang. Wounded, Jackie restores his powers using the Darkness. Aided by the Darkling —a goblin-like familiar—Jackie pursues his attackers into the subway. A vision of Jenny appears, then Jackie is apparently hit by a train. Jackie seemingly awakens to find himself in a mental institution, where various members of his crew are patients and staff.
Jackie can use various firearms, such as submachine guns, shotguns, and assault rifles, and has the ability to dual wield some of these weapons. Additionally, he is armed with a pair of Demon Arms, which resemble tentacles and can be used to slash enemies or pick up various items within the environment (parking meters, car doors, etc.) to use as projectile weapons or shields. The Demon Arms can rip out the heart of fallen enemies and devour them for health, pick up enemies for execution, or throw them.
