Wall running is one of the abilities that you unlock in Star Wars Jedi: Fallen Order. After you’ve been introduced to Cal Kestus you’ll find yourself on the remote planet of Bogano. You’ll notice as you explore the planet that there are some areas that look like prime candidates for wall running. However, you’ll need to wait until you’ve reached a certain point in the game where you’ll receive the power-up.
You’ll get the wall running ability after a flashback sequence where you remember your Jedi training as a boy.
Wall running in itself is easy to do. Simply jump towards a wall with ridges on it and you will begin wall running. Once you get to the end of the wall you can press the jump button to jump off of it. This will be the Space Bar to Jump on PC or the A Button on Xbox / X Button on PlayStation.
You cannot use the wall running technique on all walls. Only walls with ridges on them are able to be wall-run on.
