    Reborn InsanitySpent all day and checked all 45 spots just to make sure I didn't miss anything and it's only showing 44/45 facepalm

    Great guides though. Looks like I'll be checking all 45 again.

    SoppiestSquash8I've done this one probably 5-6 times over the years and have never gotten it to pop. I'm not sure what I'm doing wrong but I'll give it another try with these videos and see what happens. Thanks for posting!

    I used these videos. Not sure if they're in the same order as VI TRELON IV's list, but they should be.

    SwervinCurvinI was missing 2 caches when I started using this. Great vids, and yea, the music sucks.

    Living LegendsI like written over videos because some people get it out of order or is just too much trouble scrolling back and forth in case you forgot to pause or had to stop watching for a few seconds.

    The AcheivementI much prefer written to video. This was a lifesaver.

    SmactSillyI always prefer written guides unless it is too hard to describe in words and a video really is necessary. Thanks for providing this in written form.
