When you are battling Lou on level 8, fail it, then go to the tutorial and pick Guitar Battle. Then, after the tutorial is over, face Lou. His difficulty will be brought down to easy. After you beat Lou, Through the Fire and Flames, will be unlocked.

After Lou gets his first attack, you will see an arpeggio of Red, Yellow, Blue and Orange. You will get an attack there. If it is a whammy, use it when Lou has the string of greens in the immediate next solo he has. Watch as his rock meter suffers!

Like Guitar Hero II, while playing a song on Hard, it is almost like the notes on expert. So, after experimenting playing a song on Expert. I have concluded that you can play hidden chords in any song. (I do a lot of chords to try to get more acheivements, hope this works for you, too).

When you reach the Lou, who is the devil. He can give you a death drain. But only if the devil and you don't lose. In sudden death, the devil plays until he hits death drain and you don't play at all.

During battle, when they use lefty flips, look on your opponent's screen, if your playing the same difficulty.

Use the Whammy Bar on every held note on Number of the Beast

These are the steps to get a 15G Achievement. First, complete a Career on Hard or Expert. Save your game, then turn off your Xbox 360. Turn your 360 back on with the standard controller. -Go to career you completed and BAM! Achievement unlocked.
