Seriously. I never thought I'd see the day.
The hardest song of any Guitar Hero or GH-like game ever released met it's master yesterday, when some dude named Chris hit every one of the song's 3,722 notes in stride. His reaction at the end of the video says it all... he definitely didn't expect it could be done either.
Grats on an epic gaming moment, Chris. You better not have been cheating! ;)
