This difficulty is known as "Mythic" which refers to Single Player on Legendary with All Skulls On with no deaths. Just to lay down some framework: My experience: Mythic Conqueror of Halo CE Anniversary, Halo 2, Halo 3, ODST, Reach, Halo 4, and Halo 5 campaigns. SLASO = Solo Legendary All Skulls On. Mythic = SLASO + no use of save & quit + no deaths + scoring and a film. SS = Single Segment - completing the level in one run without deaths.
