You're probably asking right now, what is Rocksmith? That's easy. Rocksmith is Ubisoft's upcoming venture into the rhythm game market which won't be compatible with any existing plastic instruments. Instead, the game will use a real guitar. The bundle will include one and will be available for $79.99, and if you pre-order at GameStop you'll receive a voucher good for $25 at Guitar Center. Of course any guitar you already own will work just fine. For more information check out the official Rocksmith website, and keep an eye out for more news on the game which is scheduled to launch this fall.
