Gangs of Mega-City One
Gangs of Mega-City One was a warband game released by Mongoose Publishing in 2004. As the name suggests, it is set in the world of Judge Dredd, allowing players to assemble bands of criminals fighting for wealth, fame and entertainment in the stifling, overcrowded confines of Mega-City One, a post-apocalyptic version of New York City.
The initial sourcebook focuses on human crooks, with Specialists bringing in many of the more iconic weirdos of the MC-1 setting. Its only sourcebook, "Death on the Streets", added three new gangs; robots, intelligent apes, and Under-City Freaks, a mixture of mutants, outcasts, werewolves and other weirdness.
Gangs of Mega-City One was retired and replaced with the new Judge Dredd Miniatures Game in 2009.
