you dont have to be camping to get a nuke.yesterday i got my first nuke by being aggressive with an intervention.it also makes for some interesting youtube vids if you use the intervention.

Woah cool. If only you got that on video :/

I'm aggressive most of my kills but when I get to 20 kills (which is usually after the chopper) I get really fucking nervous and I panic. So I camp in a place (I'm so ashamed ;-;) and get the last 4 kills. Hardline, oh do I love you.

i shouldve cus i just asked my parents to buy me a catpture card, so expect a video maker by my name on youtube some time soon.
but it helps not to worry about your kill streak.also i use different tactics on different maps like this is what i do on skidrow: i use a care package and put it out in the park/courtyard area.then i wait around as it attracts enemies, which i pick off one by one till i get a chopper gunner.then i just try to get at the nuke in chopper gunner.
