Black ops 3 Glitch Host one man lobby. MAX XP CAMO!

This works on all game modes. but domination is unlimited time if you dont capture the zone. One man lobby! First start playing a game, play until you are host, you know because the begining of the game start time is over 10 seconds. when you know you are host finish the game and stay in the lobby. during intermission open spotify that will suspend black ops 3 pick a song and re open black ops 3. you will get the same loading screen as me if not you were not host, close spotify and try again. once you are in your own lobby have a friend join game session in progress, take turns completing challenges and unlocking camos. make sure you guys move around or will get kicked for in activity and end the game. ive confirmed this working on all diferent game modes.
