From the Back of the Book:
Batman's fate depends on you!
He's up against the craftiest criminals that ever tried to foil a crimefighter. The Joker wants to shrink him down to mouse-size. Two-Face has a clever plot to uncover his secret identity, and The Riddler wants nothing less than the end of Batman forever! But you can help Batman outwit his arch-enemies. You're in charge of the Caped Crusader's every move. But if you accidentally put him in dire danger, don't despair! You can always go back and choose another path... one that'll put the villains behind bars, and send Batman off on another thrilling adventure!
