As u know, Miles y the maze made by Bungie, this map has many kind of obstacles, and if u give a bad step, u will have to restart since the biggining, thats why many people cant finish it, they dont have the pacience, but in this video, i finally, after the 100000 tries, i owned Miles finishing it, u have to see the map (if u havent see it), and u have to see the way i finished it.
