How do you glitch in combat arms

In combat arms there are many glitches i am aware of. They include: Junk flea and Two tower. In Junk flea where the Bravo base, just outside of the door upstairs there is a gas tank. You can jump on top of the gas tank then attempt to jump onto the top ledge of the open door. Once landed on top of the door you jump straight for the ledge of the roof and there you have it you have landed on the roof. (Use the knife i am not sure if it is patched) In Two tower at the bravo base,go up the stairs located to the left of the open ledge where you can jump on and walk. Go up the stair and to the open door in front of you and on the left there is a balcony sort of thing. Look down and jump onto the ledge beneath it, then jump onto the right ledge. This glitch works in quarantine mode the best. You will need two people to attempt this glitch. Get your partner to stand beside you while you face the corner wall where there is the diagonal long wooden sticks. Next run towards the wall or the sticks and try to jump onto the stick and sprint. After head towards the wall and knife it then run and crouch while your partner is crouching or standing beside you the whole time. It may take a few tries to glitch through the wall. If you have any questions write on my Youtube channel called iLikeCookiesToo. I will be posting future videos of my glitches. Have fun glitching and playing combat arms while it last. =)
