From the web-site: B'hoys! is a detailed game system based entirely upon Herbert Asbury's The Gangs of New York. Emphasizing the fluid nature of mob vs. mob street-fighting, and the dynamics of such contests, the rules use specially designed Action Cards to determine order of movement and cue test points for "Resolve". Rules cover Gangsters, Police and Soldiers as well as "Laundry Guards", Barricades, "Barking Irons", "Irish Confetti", "Banshee Screams", "Eye Gouging", "Biting Attacks" and a wide range of street weapons and brawling techniques.
