Well, this is a glitch that will allow you to get two killstreaks (same killstreak i.e 2 Chopper Gunners) by just getting the amount of kills necessary for one.

1. To start you requiere a game that has atleast 2 rounds(Demo, SnD, CtF)

2. Your class setup can be anything you want, just that you are required to have HARDLINE

3. Lets say you want double Chopper Gunner. You have to get the Chopper first legit (meaning 8 kills because of hardline)

4. After you have the 8 kills, you can either use the Chopper Gunner or not but you can't kill with weapons / grenades or anything other than killstreaks (meaning your killstreak count will stay in 8 )

5. After the round has ended, switch to a class that does not have hardline . You will start the next round with that class and just get a kill. (After getting a kill, your killstreak count will be 9 and will get you a second Chopper Gunner)
Then you can proceed normally and thats it.
