Haven't played any MP maps yet, had to DL and apply the patch. The singleplayer is MUCH harder. I put it on easy just to explore some of the new maps without having to worry about getting wasted, and I got tagged alot more than you normally would. It is alot harder to take down the flags. It used to take only a few minutes to go into single player and take downt he win by flags, but it took alot longer to do so now. The new vehicles are great, the new weapons are great, I don't know how many times I got flashbanged by the CPU, and the gas effect is pretty cool. I like the night maps too. The Spec Ops job seems to have got the biggest win out of this expansion, with the addition on the grappling hook and flashbangs. They can get you almost wherever you want, and get you out of any situation.
