Call of Duty Black Ops 2 (no idea what my K/D was but I had about 50 hours playtime online)

Haven't really played much else online for long, never got into Battlefield 3, never bothered with 4. No interest in CoD Ghosts and so on.
I still need one more mp trophy to MoH. I've put quite a few hours into it and lone wolf style just isn't cutting it
