I know a way where you only need 4 people to boost and poeple that you invite can join anytime and still be locked.
1st go to ground war for a sec and back out(HOST) everyone will back out immediatly with doing anything .
2nd go to Barebones
3rd hold x(xbox360) i dont know it works for ps3 so just hold square until the ga,estarts and when the countdown finishes like 9...8...7...6...
4th it must be free-for-all right when you go to barebones
5th host must leave and someone must invite him
6th when host come back whoever invited him has to leave
7th host invites the person who left
8th the lobby is NOW LOCKED AND YOU CAN PLAY ON TEAMDEATHMATCH WITH 4 PEOPLE AND EQUAL TEAMS
- If you cant do it or dont know how send me a message on XboxLive Gamertag: The xZLegendzZx and ill do it for you
