You need yourself and 3 of your friends in a modern warfare 2 party. select find match and select barebones pro. once in a lobby where it says its searching for other players, get your friends and you to press and hold X on the xbox controller. also, vote to skip the current map. if done correctly it should close the lobby from other players entering and enter the intermission countdown. there you have a boosting lobby with your mates. would be much appreciated if you could press thanks and give me feedback hope this helped guys
