Uncharted 2 - Double Chapter 5 Fight Skip!

You could originally skip the second fight but it required you to do a really long airwalk. My method is wallbreach (not pressing L1) and then a tiny airwalk to the ladder from the truck. You probably couldn't do this on anything other than Very Easy or the enemies would mow you down before you could glitch out.

I know the wallbreach takes me awhile but the one shown is like average (plus I only just got used to doing it without pressing L1). The breach could easily be improved by like 10 seconds and probably even more. Make sure the game fully loads the next area before you jump out.
