Knuckles of Steel is a blaxploitation scenario for Wretchploitation (or other contemporary OSR games) and the second in a series of modules taking place in Crime
City, the fictional metropolis introduced in Sexual Holocaust.
The adventure is pretty straightforward: A triad crime boss kidnapped his former girlfriend's sister and uses the hostage to persuade Lois, model and aspiring actress, to marry him against her will.
However, Lois still has a card up her sleeve: A group of brave, determined and wretched
friends willing to help her no matter the odds. A situation like this could be solved in a one-shot, but Knuckles of Steel provides plenty of plot hooks and non-player characters and places in Hammettville.
