Step 1
Push the 'W' key to get an initial run up.
Step 2
RELEASING the 'w' key press the strafe key (D or A) and move your mouse in the direction of the strafe(ie: if 'A' move mouse left in a little arc or if 'D' move mouse right by say 30 degrees) + JUMP
Step 3
You will now initiate a forward curved jump , in the left or right direction(Please note never to use the 'w' key for acceleration here after).
Step 4
When your about to land after the first jump, hit the opposite strafe key and curve your mouse in the same direction of your strafe and hit jump EXACTLY when you land after the first jump. Doing this a little too early or little too late will cut the bunny hop.
Step 5
IF You got the timing and mouse movement right you will quickly move forward faster, and you will need to repeat Steps 2 to 4 repeatedly.
