Death doesn’t matter to Brandon Heat. Driven by vengeance, he’s back from the grave and bent on crippling Millennion, a massive mafia organization with legions of undead monster enforcers. Armed with his twin handguns—Ceruberus—and a coffin full of heavy weapons, Heat won’t stop until Millennion’s leader—and Brandon’s former best friend—Harry McDowel is destroyed.
