How do you get a nuke? Do you camp, snipe, run and gun etc. Also what game mode do you do it on, TDM, Domination, etc.
I usually try to get it on domination on Sidrow but I always die a few kills before. Today though, I helped my friend get his first on Run down while we sniped. I think he went 33-2 and I went 29-5. I think the best way you can do it is have a friend help you out and cover you.
