Rock Band 2 is the sequel to the revolutionary music game that introduced cooperative band gameplay, multiple instruments, and a robust online multiplayer experience. Building upon this foundation, Rock Band 2 ups its game by delivering an entirely new level of depth, connectivity, authenticity, and features. These include backwards compatibility with previous downloadable content; the largest and most diverse soundtrack ever featuring master recordings from rock's biggest names; major new online modes to connect players locally and globally; more instrument choices than ever before; and improved drum and guitar peripherals with enhanced functionality.
