Overview
Do you want to ruin your HL2 experience with 2 simple glitches well your in the right place!
Backhopping
Ever feel to slow, Well do not worry, there is a BHOP mechanic called backhopping that is easy to do that lets you travel at insane speed, Especially in any car/vehicle section of the game.
Step 1
Enable you console in advanced keyboard settings.
Step 2
Open you console and enter these two bind:
Bind mwheeldown +jump
Bind mwheelup +jump
Step 3
Jump and do a 180 so you are traveling backward and then hold crouch before you hit the ground.
Step 4
Do not press any movement keys and then start scrolling, This should be before you touch the ground again.
Step 5
Get to a high speed. Then you can either try to hit a ramp and go flying then turn around and start to change your direction with strafes or not hit a ramp and turn around once you have reach your destination.
Use Climbing/Hopping
So here is another easy yet overpowered glitch
Step 1
Bind scroll to jump (Explained how to in Backhopping)
Step 2
Find a prop that you can pick up with out the gravity gun, I found that the following props worked the best for this
Step 3
Place the box in front of a wall
Step 4
Jump onto the box then start scrolling and spamming E whilst holding W
Step 5
Do step 4 until you reach you desired height
