Ok I know this game has been around a LONG time and there are plenty of good guides already written. However I did not like any of the video guides provided. So I figured I would list the video I am using for this Chievo.
Hope there are still some out there that will find this helpful. I've slowly been coming back to Halo MCC to chip away at the mount Everest achievement list..... some day I'll crest that mountain!
Obvious Items: Level = Keys & Difficulty = Heroic (at minimum)
