Vid tut: youtube.com/watch?v=SKDo8R5vkSw (like the video if you're here before the processing) - Post GT's below to get in (You will see what i do in the video - i can vouch i invite you in)

Text Tut:

*Make sure your mate is in a custom game with join session OPEN, and no one else must also be in his lobby, also ask him to choose the map you want to play*

SET PARTY TO 4 MAX + OPEN PARTY


1) Search for Combat Training 3 times (Back out and in etc)

2) Hover over public match and press Y

3) Scroll down to your friend who is in the custom lobby

4) Press X and A (Join session) , continue to spam A

5) Make sure while doing this your mate is hovering over yes to leave lobby

6) Now the moment your join the lobby, get your mate to back out

7) If done right, you'll notice just you in the lobby

8) Quickly go to player channel before the lobby kicks you

8) Once in Player channel invite your mates

9) If your mates see (Waiting for X amount of players) you have done the 'locked online lobby glitch in which only friends may join. The lobby will also stay locked forever!

10) If your mates see NO MAPS and the game isn't searching for X amount of players, then you would have done the custom XP Lobby which is a custom game online, your friend's map will also be played through

It is completely random which one happens, but the important part is to make sure you stay on your player channel until the game starts.
