They weren't always secondaries?!?
I play it...rarely. I'm pretty busy (as I've been mentioning more than necessary), and play only a few times a week.
And though I've learned the beauty of a M16 and a 1887 (singular, 1, A, I heavily dislike the Akimbo 1887) I'vve also learned this: In my house, the longer you play the game in one day, the increasingly worse you do.
They weren't secondaries in CoD 5. All there were in Cod 5 for secondaries were pistols.
Same with CoD4.. Anyway, You can use secondary weapons as primary weapons now. It sucks. I keep getting owned by a PP2000 or Spas-12 every time I turn a corner.
I've discovered that when I'm doing my best and just so happen to get a 25-kill streak, I didn't have nuke on, yet I had UAV on, so I could have easily replaced UAV with Nuke and nuked their behinds.

I've had like, three 25 kill streaks this week already, yet none of those times i had nuke on.
I've never called in a nuke before, but I have had plenty of 25+ kill-streaks.
My best ever match was in Free For All, I got 30-0.

And I wasn't camping. I was running 'n' gunning. Although I did drop shot a fair bit, so I guess that's why I didn't get hurt so much.

Anyway, it was on scrapyard.
And that map pack they recently released, I am definitely not getting. Screw them for putting it up to 1200 MSPoints. I can buy a full arcade game for that price. A
GOOD full arcade game.
Although the "Mapathy" trailer they released for it was hilarious.

Anyway, the M16 is alright.. I don't like it that much. You DEFINITELY need to try out the Tar-21 without stopping power. It still rips up as if it does have stopping power. Try it with FMJ, you just get a sense of power and you just rip people up with it. I have had 2 25-kill streaks this week by using my class with Tar-21 FMJ and Hardline, with killstreaks as UAV, Harrier and Pavelow.
Seriously, Tar-21 is very overpowered. But then again, so is the FAL if you have good trigger-pressing speed.
