Guitar Hero World Tour

You will need to start up four separate Careers as four separate instruments (Vocals, Guitar, Bass, Drums). Play through all free gigs (gigs that you do not need to purchase in order to play) in all Careers. The difficulty chosen doesn't matter, you can choose from Beginner to Expert for all Careers.

-When you play Vocals set the difficulty to beginner, then place the mic in front of something that makes enough noise for the mic to pick up the sound (any speakers, fan, etc.) and let it sit through the songs.
