2nd. go near the corner which is next to the window on your right...and try going prone and try to get your feet into the wall .. if done right..you will see the wooden piece on your right and you wont be able to turn right or left with your left stick...
3rd. Let the other person Run towards you and dive on your head...If he freezes in the air the glitch worked..
4th. Stand up and Enjoy!
