Afterward, host a private match or a split-screen match. Have your friend pick Hardline and the Pavelow as one of their Killstreak rewards. Let your friend kill you enough times until they have their Pavelow. When their Pavelow is out, use your rocket launcher to hit it. If it is not destroyed the first time, use your Scavenger perk to get more rockets. Immediately after the Pavelow starts to spin out of control, take out your light machine gun and shoot at it. Each bullet that hits the spinning Pavelow will count toward Cold Blooded Pro. This way, you can easily earn Cold Blooded Pro within a five minute match.
