In Alvin and The Chipmunks: The Squeakquel, players can play as Alvin and The Chipmunks (Alvin, Simon, Theodore) or The Chipettes (Brittany, Jeanette, Eleanor). Musical sparks ignite as they jet around the world, rock the house in 25 concert locations on Wii and 11 in the Nintendo DS version, and perform together in the ultimate concert finale. Featuring songs from the Grammy and American Music Award-winning Alvin and The Chipmunks library, the game lets players use the Wii Remote and Nunchuk or Nintendo DS stylus to keep the rhythm in the main game and in three mini-games. Players will gain thousands of fans by keeping the band on tempo through songs that grow more challenging and complex.
