Halo Xbox tip details

Jump back on that walkway [The Maw, Light Fuse, Run Away]

In the "Light Fuse, Run Away" area, after destroying one of the engines, if you jump at the walkway and crouch at the apex of your jump, all while moving forward, then you should be able to get back on the walkway. To put this in simpler terms to Half-Life vets, do a duck-jump.
