As with BF3, just Amazing!
The Spec ops is sweeeeeet, my son and I had a great time killing wave after wave. We set up a plan as the waves continued to get harder by laying claymors and anything else the fine people of MW added to the goodie boxes!
The multiplayer is fun as well, I don't like how we have lvl 30+ players running around with so many modded out guns, ect. It kind of killed the exp for the new player.
I love all the maps added to the game, so much to do, with spec ops (survival, mission), single player (easy, normal, hard, vet), online with the new game types, a person should have many hours of fun. I give this game a 9/10. It would get a 10/10 if they made it more war like in multiplayer.
