The game is largely based on the movie. Bruce Wayne returns to Gotham City after several years of disappearance and training in the Himalayas with the League of Shadows. Donning the cowl and cape of Batman, Bruce Wayne discovers secrets of unusual powdered toxic shipments at the docks which leads all the way up to the scheming Dr. Jonathan Crane a.k.a. The Scarecrow. Of course, there is more to it than Bruce/Batman realizes.
Fear is your weapon.
Did You Know?
The first thug we see Dr. Crane get off with an insanity defense is named Zsasz. If you look closely, you'll see he is covered with scars. In the comics, Zsasz is a homicidal maniac (mentioned by Flass) who keep score of the people he kills by marking it on his skin. Every one of those scars is supposed to represent one of his victims, and although you don't see it in the movie, his body is covered. Note: This trivia entry is for the movie, not the video game.
