Big Boy has escaped from prison and is trying to reclaim his crime rackets. The only person who can put an end to the syndicate and put him where he belongs is Dick Tracy. You take control of Tracy as you fight your way through a number of cases, searching for clues and fighting thugs and adversaries. You can shoot the armed bad guys with your trusty firearm. However, shooting an unarmed criminal will result in a penalty, so you have to be careful with your shots. There are several weapons scattered throughout each level that will make things easier, including a Tommy gun and tear gas. It's up to you to stop Big Boy and take a bite out of crime.
