This can be done on any game mode but the 3 modes that I recommend the most is

1, Headquarters 2, Demolition 3, Hardpoint

The method is the same in each mode which i will explain shortly.

First thing you need to do is get a party of 6 people with 2 controllers each.

Split the group in to half so 3 people with their guests in one party while the other half of the party wait to join the game which brings me to my next point.

1. Go to the xbox dashboard, Settings, console settings, change local, then pick a random country like Hong Kong, India, etc
(i pick India and never have trouble getting an empty lobby)

2. When you search for a game (where it gives you option to pick a game type press X and choose "Best Connection"

Instead of doing the above you can run loads of you tube videos to slow your connection, i do the above as you don't have to have multiple tabs open

3, Once in the empty lobby invite the other half of your group

You may have some trouble getting the other half into the game due to the BO2 server issues but have patience you will get them in eventually.

Before the game starts you need to partner up. Once this has been decided amongst yourselves you are ready to boost.

On your main controller you can use what ever weapon, perks, etc you like as you will be leveling up on this account obviously. the one thing i would advise is have a UAV and COUNTER UAV you can call these in while boosting to bet more score/xp with out it effecting any one else in the lobby

However on your second controller all you need to do is pick the "specialist" standard class as it has a tactical insertion.

1. Arrange where to meet your partner it makes it easier to leave the guests at spawn. (unless your doing domination then move them to the flags to get more xp. Just careful not to end the game prematurely by capturing them over and over.

2. When you with your partners guest have them on their second controller place their tactical insertion down.

3. Kill the guest account over and over while calling in your UAV and Counter UAV's

4. On your second controller when you die press x to respawn quicker and put your tactical insertion down again, repeat this through out the boosting session.

5. If you use any other score streak Do NOT use EMP Reason being it destroys everyones tactical insertion on the oppsing team causing the boosting to get delayed and a lot of running around with your second controllers

6. Keeping going until you have reached your desired kills and have fun!

7. Optional - to make it seem more legit kill your main account a few times so its like 76 kills and 20 deaths for example. As stated optional up to you.

1. To much XP will get you de-ranked. Not banned de-ranked. To ensure you dont get de=ranked i stop getting kills at 70 or 80. Others have confirmed they have gone to 100 kills with no reset but choose what ever works for you.

2. Do this over and over with no legit WILL get you high on the leader boards and then banned so make sure you are mixing it up with boosting and legit.
