(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.

Why dont you just get the play to look at your name and while your searching for good games they can join they get in everytime

nice find it is simple too

Ok even easier way just have him join ur session while ur searching for a match.

Just tried it and it worked. Thanks!

Yea I did this in COD4.
However, when I do it in MW2 my mate automatically backs out with me. :/ Your friend needs to have a good connection to migrate the host after you leave.

awesome this works

Yeah..this is what I do too. Its very simple and works almost every time.

Nice ill make a vid and send you link
found by you OBV !

glitch works but doesnt work once ur friend gets into ur cage match it says searching for more players and never starts
