Rock Band: Unplugged

Rock Band Unplugged is an expansion of the series of music video games to released for the PlayStation Portable. The core game is functionally similar to the note-matching gameplay of Harmonix' previous titles, Frequency and Amplitude, with the player responsible for playing all four instruments (lead guitar, bass, drums, and vocals) using the PSP's controls. Game modes are similar to Rock Band's, and the soundtrack includes a number of songs that have already been a part of the Rock Band series. Additional tracks will be a time-limited exclusive to Unplugged before they are released as downloadable content for the console games. The game supports the addition of new songs that can be purchased through the PlayStation Store.
