Rock Band 2

Rock Band 2 is a music video game developed by Harmonix Music Systems. It is the sequel to Rock Band and is the second title in the series. The game allows up to four players to simulate the performance of popular songs by playing with controllers modeled after musical instruments. Players can play the lead guitar, bass guitar, and drums parts to songs with "instrument controllers", as well as sing through a USB microphone. Players are scored on their ability to match scrolling musical "notes" while playing instruments, or by their ability to match the singer's pitch on vocals.

Rock Band 2 features improved drum and guitar controllers, while supporting older controllers, as well. New features include a "Drum Trainer" mode, a "Battle of the Bands" mode, online capabilities for "World Tour" mode, and merchandising opportunities for the players' virtual bands. In addition to the 84 songs included on the game disc and 20 free downloadable songs, over 1000 additional downloadable songs have been released for the Xbox 360, Wii, and PlayStation 3 versions, with more added each week. All of these songs, existing and future, are compatible with all Rock Band titles.

Rock Band 2 software was released in North America for the Xbox 360 on September 14, 2008, along with individual instrument peripherals. The software/hardware bundle for the Xbox 360 was made available on October 19, 2008, the same date that the PlayStation 3 versions of the software, hardware, and bundle of the two were released. Versions of the game for the Wii and PlayStation 2 platforms were released on December 18, 2008.

Rock Band 2 received highly positive reviews from critics upon release and sold 1.7 million copies through the end of 2008.
