Halo Reach Oni Sword Base Mythic (LASO, no deaths, no save and quit)

The mythic challenge is beating halo missions on Legendary with all skulls on, with no deaths and no saving and quitting. While one of the skulls restarts the mission when you die, you can get around this by saving and quitting during the death animation, and reloading. This will bring you to the last checkpoint before the death. You can also use saving and quitting whenever you get into a disadvantageous position to prevent deaths. Because of this the mythic challenge bans saving and quitting. Description of all skulls: https://www.halopedia.org/Halo:_Reach...
