Single-segment speedrun of the 343 Guilty Spark level (level 6) of Halo, performed on Legendary Difficulty. This level was designed to be multilevel, with a route that took you through both upstairs and downstairs - this run shows how the designers' wishes can be easily circumvented with some well-placed grenades. The run (by Tristan Cahill) was the level winner in a speedrun contest held at halo.bungie.org in the summer of 2004.
