Can I Beat Halo CE Legendary Under 3 Hours GLITCHLESS?

Hello fine Frogarchist (pronounced Frog-are-kist) viewers, today I overreacted to a random YouTube comment and was inspired to see if I could get the Goat Roped achievement without doing any glitches or major speedrun tricks. Can I? Tune in to find out! Or don't, idk you could just fast forward to the end I guess.
