Rock Band Unplugged creates a full band experience in the palm of your hand by combining traditional beat match gameplay with key elements from both Rock Band and Rock Band 2, such as overdrive and chords. Your hands are the "peripherals" in Rock Band Unplugged allowing you to take direct control of the lead/bass guitars, drums and vocals. In addition, players can expect a rich Rock Band experience with fully functional modes like World Tour, Band Survival and Warm Up and a robust character creator for full customization!

Rock Band Unplugged will feature over 40 master-recordings including nine brand new, exclusive songs for the PSP for a limited time! Plus, Rock Band Unplugged will include the first fully-featured in-game store for downloadable content on the PSP in the North American and European markets, leveraging the PSP's wireless capabilities. The in-game store will be powered by PlayStation Network, and players will be able to use their existing PlayStation Network account to purchase tracks, similar to the Rock Band console experience. PSP owners will also have the option of purchasing tracks via PlayStation Store on the PC.
