This is a glitch i found awhile back. If you angle yourself straight, forward facing the wall you can use your force jump while holding back on the analog stick to scale it. Angled walls/V walls are easier, flat walls are the hardest. Very useful in a lot of areas of the game. If someone does more experimenting with it, i'm sure there are parts of missions you can skip completely. Be careful though, there are death barriers everywhere outside the maps.
