As a member of the FBI, you wear the badge of the bravest. Your mission: rid the city of these thugs. Armed with your machine gun and plenty of courage, you’re dedicated to making gangsters a thing of the past. But it won’t be easy. The streets are riddles with gunfire, the local nightclubs are now criminal hang-outs, and the waterfront’s docks are in the grip of the most menacing crime-lover, Big Boss. It’s you or them – good luck, you’ll need it!
