Having had a crack at the single player and multiplayer last night, its good, but probably not as good as mw2.
I dont have any issues with the graphics, but I didn't find the level design all that. The single player levels seem to be full of bottlenecks where they just throw waves of enemys at you, rather than just make a good level lol. Wasn't mega impressed with the multiplaer maps, but only played about 10 games so need to give it more chance.
