In some games that use the Source engine, you can perform a mobility glitch called accelerated back hopping (ABH). In ABH, you jump backward repeatedly, gaining insane momentum. This is a useful trick that can be used to launch yourself off of ramps or just travel across maps quickly. Note that you will need a mouse to ABH.
Steps
Setting It Up
-
1Open a game that uses Source. Many games will not work, but the games that ABH is guaranteed to work on are Portal and Half-Life 2 (and all episodes).
-
2Start a new game or load a save file.Advertisement
-
3Bind your scroll wheel to jump. Press Esc while in-game and click OPTIONS . Then, click Keyboard . Click the movement called "Jump" to highlight it, and then click Edit key . Move your mouse's scroll wheel down to bind it to Jump.
-
4Resume the game by clicking RESUME GAME .Advertisement
Performing the Glitch
-
1Hold W . If you're playing a sprint-enabled game like Half-Life 2, you can start off sprinting to reach max speed sooner.
-
2Scroll down on the scroll wheel.
-
3Let go of W while you're still in the air.
-
4Move your mouse so you are facing the opposite direction. Again, do this before you land on the ground.
-
5Press and hold Ctrl while still airborne.
-
6Scroll down on the scroll wheel right before you land on the ground.
-
7Continue gaining momentum. Keep Ctrl held down, and remain facing the opposite direction. At this point, you'll want to continue timing your jumps with the scroll wheel and gaining speed. If you don't jump at the right time, you'll lose most or all of your momentum.
-
8Control your direction of travel. While you won't be able to directly see what's behind of you, you can move your mouse to change where you're looking, and subsequently, where you're going. If you look to the left, you'll head left as if you were looking forward.Advertisement

Tips
- Performing this glitch takes a lot of practice. You'll need to get a feel for when to jump so you can gain speed and not slow down.Thanks
- If you use ABH to launch yourself off a ramp or object, you'll be airborne. While in the air, you can turn around and see where you're heading. Just make sure to turn around and hold Ctrl again before you land.Thanks
