Nitro City, 2033. Leon "Catwalk" Caliber left his cop job in DC behind, heading to the City of Angels to earn a living off the grid. He took a few odd jobs that called for his particular skill set - extortion, espionage, and the occasional hit - and managed to carve out a niche for himself among the Downtown dwellers. All that changed when a new breed of MetaHuman cyborg appeared on the streets with explosive violence. Cat's quiet existence is sent into turmoil when he finds himself right in the crosshairs. He must evade the assassin squads sent by a vengeful pimp, uncover the origin of these mysterious new mechs, and keep the cops off of his tail. Simple enough, except that the cybernetic technology that powers his body threatens to sever his humanity at any moment. Can the killer with a conscience find a cure, solve the case, get the girl, and live to see another day?
