This is a video of filthy liar/cheater Cody Miller attempting to replicate a Halo: Combat Evolved speedrun he posted online (years later revealed to have been a bunch of individual videos spliced together) as part of a 2011 Games Done Quick charity marathon. In the video he’s attempting to complete the game on Legendary difficulty with a finish time of around 2 hours, but eventually has to turn the difficulty down and still finishes in over four hours. The whole thing (which has been edited to 20 minutes) is painfully embarrassing to watch. Wow! This has been a PSA reminding you to not be a Cody Miller.
