(adsbygoogle = window.adsbygoogle || []).push({}); This is the SIMPLEST way to get get into a cage match with a friend EVERY time. If you can't do it then I'm sorry, but you don't even deserve to have the game. It's probably a medical miracle that you're even alive today with the severe lack of oxygen to your brain.
But I digress!

Tutorial is as follows,

TUTORIAL:

Step 1: Be at the main menu with your mate, at the part where you can pick any game mode you want.

Step 2: Select any game mode CLOSE to 3rd person cage match.
(I suggest Hardcore Team Deathmatch as it is only 1 up from 3rd person cage match.)

Step 3: When in the game lobby, leader of the your party backs out. This will mean you are in the main menu bit by yourself, as your freind hasn't backed out yet.

Step 4: You search for 3rd Person Cage Match at the same time as your friend backs out of that previous games lobby. (It is best to be in contact with your mate to get him to back out at the right time, but not essential.)

This will put you in with your mate!

I told you, ****ing simples. If anyone would like to help me record this on Xbox 360, it LITERALLY takes about 9 seconds and I'm sure would help the community if they don't understand the tutorial.
EDIT: Thanks to Rhyss 94 for recording and getting this video up: [ame="https://www.youtube.com/watch?v=liw26qTMns8"]YouTube- *NEW* 3rd Person Cage Match Glitch - Modern Warfare 2[/ame]

ANOTHER really cool thing you can do with this glitch is have 8 players in a lobby, search for anything, then do the glitch but search for free-for-all. This will put ALL of your 8 mates into a game with you. Do whatever the hell you want!

Please comment as I would like to hear your opinions and stuff. Also please thank and +rep IF you think I deserve.

Exactly, it's so simple. It' genius. If you read it, you'll see most of the typing is just telling people that if they don't understand it then they're absolute inbreds. Ad Ihate to argue over the internet aswell, so I'm now officially O-U-T.

Lol that's not even an exaggeration is it :p
