Harmonix first introduced us to the Guitar Hero series on the PS2 back in 2005 before reinventing the genre with the creation of the Rock Band series. Neversoft took over the development of the Guitar Hero games, beginning with Guitar Hero III and its follow up, Guitar Hero World Tour. This was their first attempt at a game that allowed for the full band experience that Rock Band had already offered. Although there were some songs that had already appeared in the Rock Band series, there were many exclusive tracks in this game. Read more about the game, including what tracks are available and how to unlock them.
