Tom Clancy's Splinter Cell: Pandora Tomorrow HD

When you are in a narrow passage, if you double tap Same will jump up and prop himself above by using the walls as leverage. This sort of tactic is rare and is not really useful. During Mission 1 the game will tell you to do this about a 1/4 of the way into the level. Do so, drop down by pressing and the repeat 4 times and the trophy will pop.
