The creator of Rex Mundi presents his vision of a shattered alternate future, as brutal gangs struggle for supremacy in a New York City ravaged by nuclear war. All that remains of the once mighty city are skeletal, irradiated skyscrapers, inhabited by thugs who abide by their own twisted rules. While crime lords vie for power and amoral paramilitary forces torment survivors of the devastation, one skilled outcast—the mysterious Zero—uses his strength and wits to stay a step ahead of everyone. Working for anyone while pledging allegiance to none, Zero is a bounty hunter who hunts the dregs of a ruined society . . . he is the Zero Killer.
