Guitar Hero III Who Needs The Power Achievement

Right, the first point is that I am not good at Guitar Hero. But the main point is that I want that "Who Needs The Power" achievement which is to get 200k on Cult of Personality. Now, I really cant do it. Is there any glitch on how to do that achievement?

Any help will be great. Thank you.

To get that achievement you'll have to do it on Hard or Expert difficulty; if you do it on Hard you'll have to hit at least %9- of the notes, and on Expert you'll have to hit a substantial amount of the notes.

I'd say practice, as that's the only way you'll get good enough to be able to do it. And no, there isn't a glitch I know of for that achievement.

Is this possible on hard?Joe91L
