Two things I've done:
1.
no scope a guy in the chest then pummel
then hit another guy
then hit three guys with one bullet, sniped one of them
then got another, and noscoped a third, getting me a triple kill and for some reason an extermination
then I sniped one more guy for my team's win
2. One of my first ninjas <3 Saw a guy on my radar, knew he was hiding. Jumped down, used myself as bait, then ninja'd the bastard.
Both those are in my fileshare :)
