Halo 3 - Sierra 117 Speedrun (Legendary)

One of the more frustrating levels to speedrun in the game, the biggest obstacle is the beginning of the level, where your weaponry to take down the Brutes isn't that great. Easier to speedrun this in Coop, where the Master Chief starts with a Battle Rifle, which can clear out the groups of enemies a lot quicker than the other weapons at hand. My best time here is about 18 minutes, my time here is 22 minutes, was a little more cautious than fast in the second part of the video than I should have been, but hopefully this provides help in how to navigate some of the trickier parts of the level.
