Once a third-rate superhero, Harvey Birdman is now a third-rate lawyer trying like hell to get by in a fancy law firm. It's not clear whether Harvey actually went to law school but he definitely knows the things to say to sound like a lawyer. And he has a suit now, that's for sure.
Over the course of the game, players must guide Harvey through a series of odd and comical cases. Each of the game's five interactive stories takes the winged crusader of justice to familiar locations from the TV show. In order to prove his client's innocence, Harvey must peruse the scene of the crime, gather evidence, talk with other cartoon characters, occasionally have drinks with opposing council, and of course, tear holes – no matter how ridiculous – in the testimony provided by the witness for the prosecution. Harvey must bring the whole story together to defend his client in a court where anything can happen
including a confrontation with the prosecution who brandishes a Shrink Ray Gun.
