Formerly the longest extreme demon in the game, and by far one of the most memorable for me. The atmosphere in this is truly one of a kind, an endless gauntlet of unrelenting gameplay, hand crafted by over 50 top players. More than anything, this level is a test of endurance, forcing you to keep your cool for over 8 minutes, lest you have to go back and do it again. I couldn't possibly imagine a version of Sinister Silence that doesn't use every second of the song.
