Dave Seville's famous singing sciuridae perform on Nintendo DS in Alvin and the Chipmunks: The Squeakquel, a rhythm-driven music game based on the 2009 holiday season 20th Century Fox feature film. The play of the game involves movement and timing, to the beat of popular songs sung by the hyper-falsetto-ed trio. In time with the music, icons move toward stationary symbols in the center of the screen, and players must try to tap the stylus in time as the icons hit the symbols. Other modes of play involve side-scrolling symbols in the forefront of the stage; players must move a cursor up and down to collect musical notes while avoiding other symbols. The play mechanics are similar to those of other rhythm-based games, such as Elite Beat Agents, using a basic "tap in time to the music" dynamic as in Dance Dance Revolution, except that the input is made with stylus strokes on the touch screen instead of with steps on a floor mat.

Taking direction from the 1980s Ruby-Spears Productions cartoon, the story of the film and video game follows the three music-star brothers to school, where they meet three signing chipmunk sisters of comparable talent and tenor. The Chipettes, as they come to be called -- Brittany, Jeanette, and Eleanor -- become both rivals and love interests for Alvin, Simon, and Theodore. In the game, single players can perform as any of the six characters, or as many as three DS gamers can play together over a local wireless connection. A story mode ties the musical mini-game performances together, following the Chipmunks and Chipettes to 11 rock & roll venues around the world. The set list includes songs made famous in the 60 years of Chipmunks stardom, as well as more contemporary hits such as "Ain't No Party," "Girls Just Want to Have Fun," and "The Macarena," based on recordings by the original artists. ~ T.J.
