Campaign
PROS:
Phenomonal. Perplexed and beautifully animated. Voice acting is spot-on. Storyline left me wanting more from the next one, though. It had plenty to twists, and general, badassery. Favorite part was escaping the gulag on the SPIE rig, and how intense it is to see the place you should have been stranded at, blow up behind you. Lack of marine storyline is always a plus. I find the TF141 so have more personality, and in general, to be a better team of fighters.

CONS: As with everygame, could have been longer. (OMG SPOILERS) Ghost and Roach die, so that's a shame. Although ghost had an exit wound, so who knows what they'll do to him next game. Intel locations were really funky, with some being right there in front of you, while others are hidden in windows. The new system with intel where you must look directly at the laptop in order to capture it is kind of bothering. Nothing too major.

Spec Ops
PROS: Tough, first 3 series of levels are enjoyable. Playing on veteran is challenging, while playing on regular to see how fast you can beat a level is very fun. I believe I've beaten the new FNG in 21.90, after around 50 tries.

CONS: Juggernauts are a bitch, 30 M240 rounds to take one down is ridiculous. Last 3 levels are almost impossible without a friend.

Multiplayer
Where to begin?
PROS: Plenty of weapons, attachments, and perk combination. Javelins and stinger missiles make tactical gameplay a factor. Killstreaks being customizable is probably the most innovative feature.

CONS: Scavenger is overpowered (I use it, I'd like to see it so that people can't spam 5 grenade launchers in one life). Some guns are still underpowered (USP & M9, formerly my favorite pistols), aswell as overpowered (ACR - no recoil; M16 - always is, always will be; SCAR-H - 3-hit-kills) C4 Sucks.

I could go on until next week for pros and cons, depending on which ones I run into.
