Call of Duty:Modern Warfare 2

I've been trying to get my nuke for the past 2 weeks and i've came close about 10 times, with 23 or 24 straight kills, but either the game ends or worse: Noobs who run around with tactical knife and commando constantly stabbing people till the point of where i wan't to find out where they live and plant c4 explosives on his porch. Still in the process though so i'll hold the c4 for later.
