(adsbygoogle = window.adsbygoogle || []).push({}); Ok... I've seen tons of posts on this, but there all way more complicated then needed.
1. Get all the people in a party
2. One person (The person who starts is the host) starts a free for all and hurries and invites party to game.
3. Once everyone one is in host backs out, then another person hurries to invite him back.
4. If host makes it back before a game is joined the lobby is locked.

So the host quits on the loading screens?

Yea when the four people are in you wont see them as matched players anymore. Youll actualy see there names, thats when he backs out.

And by locked what do you mean exactly?

how do u know who is da host?

Locked as in no one else can join while playing or in lobby so its just you 4. Making easy boosting.
The person who invites everybody is the host.

ohh kk thx

Xbox Sucks

You can just get a party of about 6 and go into a Barebones pro and make sure you get a free for all, then when you get a TDM..skip it.

Done!

True but that requires two more people (not saying its hard to get people but still.) Also if you want killstreak challenges and rewards you cant do barebones.
