Alvin and the Chipmunks is a game based on the movie with the same name. The gameplay is similar to Rock Band or Guitar Hero, but without the instruments. Using the controller's buttons, the player must hit the blue, pink, green and yellow Star Targets in sync with the music. Note streaks will give an up to 4x score multiplier bonus, but missing notes will deplete the Rockometer. The song fails if the Rockometer drops and turns completely red. (mobygames.com)
