ok to wall walk, what you do is. Run close to a wall. While pressing forward, sidestep and then force jump. and there you go. if that confuses you look for me on the zone as Locke505. I can help you, but i won't garuntee that i'll be on.
I can't seem to get wall walking down. I can do it about 50% of the time... I guess it just takes practice. It's an awesome move, though... I can see how you'd be able to get away from a something by walking right over the top of them.. on the wall, lol.
