Rock Band is the groundbreaking platform that allows music fans and gamers to interact with music like never before - challenging players to put together a band and tour for fame and fortune while learning to master lead/bass guitar, drums and vocals.

Rock Band 2 builds upon its foundation as the first music game to introduce co-operative band gameplay, multiple instruments, a robust online multiplayer experience, an unrivaled offering of downloadable content and raises the bar by delivering an entirely new level of depth, connectivity, authenticity and features including:

• Backwards compatibility with Rock Band downloadable music content. All previously purchased tracks will immediately load into your Rock Band 2 song list. No need to re-purchase or re-download.
  The biggest and most diverse soundtrack ever featuring some of rock’s most prolific acts, comprised entirely of master recordings.
• Major new and dynamic online modes that will connect the entire Rock Band community in more ways than ever before both locally and globally.
• More variety of instrument choices than ever before with new and improved drum and guitar peripherals, enhanced functionality and innovative new designs - all fully compatible with the original Rock Band instruments.
• And much more.
