This means that in addition to rocking out as a guitarist or bassist, you can also rock out on drums and vocals. Guitar Hero World Tour is a mixture of fantastic songs, refined gameplay, and superb instruments.
Let's start with the instruments. The wired mic is a standard USB mic -- nearly identical to the mic that comes with Rock Band. It works well but it would have been nice if Activision included a wireless mic. In a nice touch, you can activate star power at any time by tapping the mic or pressing a button on the controller."
