9. Guitar Hero 3 - The Inhuman Achievement
While this isn't the first Guitar Hero title on Xbox 360, it's probably the best, thanks to a phenomenal soundtrack ranging from Muse to Iron Maiden. It also includes Dragonforce's infamous 'Through The Fire And The Flames', renowned for its numerous guitar solos. This achievement requires you to beat the song on Expert difficulty; a real test of how far you've come with your guitar. The finger tapping intro will vanquish most players and that's before you've hit the wall of notes that come later. Earning this achievement proves your dedication to the Gamerscore cause... It will also serve as a reminder of the pain in your fingers for years to come.
