Have beat the game on Easy and Medium but still haven't unlocked the "Locked" songs. I see something about Co-Op or something and how do you do that without a second guitar and a partner to play with??? Just curious to find out how to unlock them.
Overall, this game ROCKS !!! This is the first guitar hero game (from the Guitar Hero series) that I have purchased or even played for that matter, and I have to say, this game is beyond fun!!! Hours of entertainment with the family and friends.
