If you wont to boost and not upset other players i know a way how to do it.First,join a party with 4 ov your mates then choose one player who is gona search for a game, then get your message screen up and b ready to accept his/her game invite. One player search for a free 4 all game this is the tricky bit,that player must then send a game invite stright away,accept the invite and then you should all be in the same game and no one can then join your game.me n my mates doit,i dont know how it works but other ppl carnt even view or join. if you need help my gamer tag is..... xCARNT B ARSEDx .. good luck.
