We've been wondering about that Death Drain in a few of the GHIII videos that happen during the song that seem random. Well, you know that meter in the middle? When it gets to the floating head, game over. It measures how much of the song has gone by, and when it gets far enough, BAM. Death Drain. If you haven't noticed, it happens right after an amazing solo. That's the legend's victory solo. So far we've seen Morello's and Lou's (the Eruption-esque part), but nothing so far of Slash's.
Wait, when did we see Lou's?
