I have the light body type and it seems that every time I sprint kinda toward a wall and sort of away i jump to the wall and like slide down instead of running. How are you supposed to do a wallrun?

You cannot do a wallrun, you can wall hop which you do by first jumping towards a wall with A on xbox(X on ps3, space on PC) and then pressing A again when you run into the wall.

You can Wallhop by jumping off of the wall. Just hit jump when you come in contact with a wall while in mid air.

I did some research and you can wall run. You jump toward the wall and push the right stick forward and away from the wall.

You can control the direction of your wallhop on console versions with the left stick - there's a limited arc based on the angle you hit the wall, so the sharper the angle, the straighter you can jump - it has about the same effect as a real-world wallrun (extending jump distance significantly).

you cant wall run you slide slowly down the wall going the direction your running making it look like your running . But look at the guy at the bottom of the screen hes not running but sliding verticaly( when you slide on ground your guys faceing "--->" this way when wall running(sliding) he "v" this way

You can sort of glitch a wallrun by holding the Smart button into the wall like your going to hop but
instead look up and towards the wall while pointing the left stick into the wall and spam the jump button
hold the smart button the whole time and you will gain hight, it's not uber useful but can get you some places
