The story involves the evil Debbie Jelinksi who is once again damaging the Addams family.
He kidnapped Baby Pubert and Uncle Fester is the one who has to find him and bring him back to his family.
The game is based on the action movie of the same name.
It is an action and adventure game with some RPG elements (you gain more hit points as you progress through the game, you can upgrade the equipment and take advantage of special attacks).
The player controls Fester by moving it, fighting enemies and regular bosses, talking to members of the Addams family and occasionally solving puzzles.
Combat is pure action, in Zelda style.
