it is a First Person Shooter or FPS, based on the first few seasons of the show.
Head to Head mode lets you pick a level and then you and a selected opponent battle it out using gizmos and gadgets. You can choose either a time limit, or a damage limit or the game can go on forever.
The game can be enjoyable and addictive specially when you face the turkey's because they are strong and "scary" a little bit..and you have many weapons to get your job done.
