The game is AWESOME! It's a lot of fun and I like the fact you don't start out with noobtube or any unfair guns. You have to work to buy guns, weapons, perks, camos, and attachments which I think it's the way it should be!
Honestly, these graphics shoot MW2 out of the water.
Only thing I dislike is the lack of game types. You need to be certain levels to achieve hard core and stuff.
Edit: And some of the spawning is a little too close to each other is small maps. I've witnessed multiple spawn kills and experienced a few myself (both killing and dying).
