Green Day: Rock Band is the second major release in the Rock Band series designed around a specific band, in this case the American punk rock group from California. The game follows the story of the band's rise to fame, with players taking on the role of Green Day and performing live shows.
The gameplay remains the same as in other games of the series: players use their instrument controllers to play guitar, bass and drum parts and sing vocal parts, matching notes on the screen in rhythm with the music. Vocal harmonies are also featured, allowing three players to sing certain parts together. The game offers Quick Play and Career modes. In Quick Play, all included songs can be played from the start, while Career mode moves through several setlists, unlocking more songs along the way. Completing challenges in Career mode unlocks pictures and videos of Green Day.
The game features 44 tracks (equaling 47 songs since some are arranged in medleys), including the entirety of Green Day's best-selling albums Dookie , American Idiot and 21st Century Breakdown (minus six tracks released as DLC for earlier Rock Band games), and selected tracks from Insomniac , Nimrod and Wanted . On the Wii version, the tracks can be exported for use in other Rock Band games.
The game was released on June 8th, 2010 for the Wii console.
