Halo 2: Easier Prison Skip Setup (Infinite Camo)

Though it loses a couple of seconds in comparison to the standard method, this setup eliminates most of the difficulty and finicky-ness of getting Prison Skip. Unfortunately, as far as I'm aware, this setup can only be done with Infinite Camo. It may be possible to do this with Envy with just a bit of tweaking. However, I don't think this can be done on Easy without some major tweaks
