To get Cold blooded pro you must have this class:
RPD/MG4
One man army/scavanger
Cold blooded
and anything else
If one player gets a Attack heli/ pave low or a chopper gunner this will work, anythin else wont work. The other player uses Harriers.
P1 calls out Heli, player 2 calls out harry.
When Heli starts spinning both players shoot it with their RPD/MG4, every bullet to pump into it counts as one kill streak you killed, so one clip with out missing means 100 killstreaks taken down.
Best to do it in Cage match.
Thanks and goodluck,
