Go to player match and invite one of your friends.

Now switch to wager match and then private match.

Then make it free for all on nuketown and start the game.

When your in the game have your friend kill you and you kill him after that wait 5 seconds and then end the game.

Disband/end the private match lobby now have your friend invite you back have your friend hit Find Match and you should merge into a lobby now invite all the people you want.
