play objective matches like headquarters and domination (or demolition...whichever requires you to plan a bomb). you get a ton of points in those matches. or even ground war.
I played some zombies with sp dynasty. I got my ass handed to me lol.
I played some free for all online and came in 2nd everytime except once o got third and had all positive k/d ratios. But I'm at lvl 10 too bad I can't see my playercard on what my k/d is until lvl 14.
I will be playing in the morning again. Nuketown is fun. I am seeing the shitty spawing crap everyone is talking about.
