Guitar Hero: Warriors of Rock

Quite an easy achievement if you have some patience. Especially if your on bass or guitar playing on beginner. But if for whatever reason you cant play the guitar/bass/drums on beginner just use a mic. Just plug the mic or headset in and play on beginner in Dominate Quest mode. All you gotta do is blow into the mic when the notes come up or if your really lazy (like me) put it up by a fan. Play all the songs in each characters setlist and "bleep bloop" you got it.

Remember to unlock Dominate Quest mode you gotta get the demigod of rocks guitar. (Beat the game basically)

Tips:
If have Star Power Tap on and have the mic by the fan the star power will normally come on as soon as you get it. To turn it on just start up a song like normal and hit start-go down to options-make sure star power tap is checked.
(If its not coming on for whatever reason to turn it on its the A button.)

Another tip: For some songs you may not get the full 40 stars if your not turning it on manually. Ive gotten 37 on Wish by Nine Inch Nails. Some songs don't have long enough vocal parts to even reach 40. (Fascination Street by The Cure) For these songs play any other instrument on beginner and you'll get the full 40 easy.
