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.

Rock Band is the ultimate platform for music fans and gamers to interact with music like never before. The game challenges players to put together a band and tour for fame and fortune - all while learning to master lead/bass guitar, drums and vocals. Featuring the most master recordings of any music game ever by the world's biggest rock artists, Rock Band includes tracks that span every genre of rock ranging from alternative and classic rock, to heavy metal and punk.

"Rock Band Unplugged reinvents band gameplay while staying true to the authentic feel of the Rock Band console games," said Bob Picunko, Senior Vice President of Electronic Games for MTV Games. "Harmonix delivers innovation with every game they develop and we are excited to continue our long-list of industry firsts with the Rock Band in-game wireless music store on the PSP."

Rock Band Unplugged will include a single-player World Tour taking you across 24 cities, and feature more than 40 master recordings from classic & current bands.
