Jersey Devil is a 3D platform game released for the PlayStation. Jersey Devil, the protagonist of the game, is the Jersey Devil, although he shares more characteristics to that of a bat. His primary mission is to stop Dr. Knarf, who tries to stop Jersey Devil with mutated vegetables. Jersey Devil uses his punch, jumping, and gliding abilities to defeat his enemies. The evil Dr. Knarf is trying to take over Jersey City with an army of mutant vegetables. You take control of the dapper hero as he explores six expansive levels looking for letters the spell out KNARF. To get a hold of all of the letters, Jersey Devil will have to battle mutant pumpkins, radioactive carrots, cavemen, and ill-tempered dinosaurs. Further complicating things, each stage is divided into three subsections with bosses to battle. Once you've collected all of the letters, a golden K appears and allows access to the levels secret areas.
There are six areas in the game with three levels each: two main levels, and a secret bonus level unlockable if the player's Nitro power level is high enough.
