Theres alot of private match glitches:)

The xp glitch, just won't work!

Private Match Glitch Steps

1. Whatever game mode you would like to boost in, go into a regular match . ex. If i wanted to demo boost.. i would go to core>demolition and click on it. You don't have to go into an actual game, just into a lobby. Go and tell your friend to invite you to a regular player match.

2. Go to your playercard > Edit playercard.

3. Tell partner to switch to combat training.

4. Tell partner to back out WITHOUT you.

5. It will then say "game lobby closed" or "party is no longer active".

6. You are now in a glitched lobby.

7. Invite you partner to your game.

8. When he is in the lobby with you, go to switch lobbies and hover over "Wager Match" .

9. Next, hit the "A" button on your controller 3 times quickly.

10. Finally, your partner's name will say "Matched Player." That means you did it correctly and now all you have to do is invite your friends to have a minimum of 6 people and you're all set. Enjoy.

Hope this helped
