Since Halo 4 came out I have been spending time on the campaign, first to go thru the missions on Legendary, then to take it further and do the missions at the hardest levels possible: Mythic difficulty or Solo, Legendary, All Skulls on (SLASO) with no deaths or save and quits. That means turning all 13 skulls on and doing a mission start to finish without dying. Proof of that for each mission is in the waypoint stats and backed up by a film of the gameplay.
I had done Mythic missions in the previous Halo games but never all the missions in one game, until yesterday when I finished Midnight. The stats and films for each mission are below:
I know that the higher priority these days for most folks is MM and customs, but for personal reasons I have not been very good company in MM and spending time on the campaign has been a great stress reliever. One great thing about the campaign is that I can yell at the monitor all I want and not upset anyone (unless one of my neighbors is home LOL). Beyond that this is a major accomplishment. I am the 4th person in the world (as far as I know) to have completed the campaign at this level.
