Ok this is a glitch i found out quite a while ago but as it seems some guy in another forum(can't say) did business with it saying he will release if people thank him. So i got pissed and im releasing it for real!!!!
STEP #1: JUMP OR FALL
STEP #2: QUICKLY PRESS "A" AND "D" !!!AT THE SAME TIME!!!
You'll find yourself floating and you won't be able to move forward or backwards but you will be able to turn. To get down press CTRL(crouch) this will get you down slowly.
