12 people in a lobby let 1 person get an ac130 and get as many kills as they can usually used to get the "spectre" challenge

i think its to do with getting the cod4 10th prestige emblem that spins round. From what i've seen, you get 8 people in a 3rd person team tactical and 1 person gets 11 kills to get the ac130 and then the other 7 put tactical insertions somewhere close by but make sure it dosent get blown up by it and u get tons of kills from it. I may be wrong, I may be right. Hope this helps

Thanks all.

AC130/Chopper Gunner boosting is basically where you get into a lobby of 3rd person Cage Match with your friends and when you get a demolition game basically they might (not sure) keep spawning at the same place when you kill them if your teammates stay at your own spawn which gets you lots of kills to get the chopper gunner/AC130 titles, challenges and emblems.

Oh and just incase you wonder that's gonna effect people's ratio all they have to do is dashboard at the end and its like nothing happened however you get all the stuff.

hope this helped
