Players are "bosses" of organized crime in Chicago during the Prohibition era. Rival gangs fight over Speakeasies, Gambling Joints, and Protection Rackets. They try to direct the public into their "stablishmunts", whilst keeping the donut-boys-in-blue out. Using their Racketeers, Thugs and Vamps the players try to obtain joints and make money from the "unsuspecting" public who just happen to walk in to them.
The game is fast moving, as each players turn is timed, and has some dire results. For example, when a hit is made the player who was shot gets a soaking (one trigger press only) with the *included* water pistol! short-straw anyone?
