Halo 2 on Legendary Completely Deathless, Zero Glitches, Killing EVERY Enemy In The Game!!!

As the title says, I completed the entire game on legendary difficulty without dying once. I didn't use any glitches to make the game easier for myself. I also killed every single enemy in the entire game down to the last infection form. I spend the first few minutes in this video going more in depth about all of the specific rules for this challenge because there are a lot of them.
