Classic Game Room presents a CGR Undertow video game accessory review of the Guitar Hero: Warriors of Rock Guitar Controller for the Nintendo Wii. With a new streamlined design and body style to match the atmosphere of the game, this guitar controller might be one of the most lean and mean guitars to date. It also features a new button to activate star power, but lacks the touch strip introduced in Guitar Hero 5. This review demonstrates the use of the Guitar Hero: Warriors of Rock Guitar Controller with commentary from CGR Undertow reviewer Kevin.
