(adsbygoogle = window.adsbygoogle || []).push({}); It says I have to get 3 kills with 1 round. I have got maybe 8-12 kills in one round, of coarse it was a machine gun, not a mounted gun. Do I have to do it online or what?

When they say "round" that is one round of ammunition. Meaning one bullet three kills

I know they meant a round of ammo, I know for a fact it doesn't mean get a triple. I have gotten 8-12 kills with one of those guns with a big ammo capacity.

it means 1 bullet ^

I have gotten it on another account and I have never had a triple in my CoD career.

maybe you did but didnt realize u got 3, i got an idea blow up a flamethrower

yes it means 1 bullet not 1 level or 1 clip

its not a hard trophy to get in fact its the only cod trophy i don't remember getting

but like someone said above blow up an ft or barrel that sound logical but bullet penetration is good and there are alot of enemys just find the right anggle and you can get 3 easy this is a easy trophy

you could easily get it on zombies

watch this, my vid, really easy to get =]
