Chicago in the 1920s and 30s runs on racketeering, bootlegging, and the kind of enforcement that money can buy, and Al Capone sits at the center of it. You are Jimmy "Machine Gun" DeMora, Capone's enforcer — the man deployed to handle disputes, suppress competitors, and keep Capone's grip on the city intact. Your job is not to clean up Chicago. It is to make sure nothing threatens the organization that controls it.
