An utterly amazing gaming experience everywhere from the singleplayer down to the multiplayer.
The multiplayer is very nice, especially if you are comparing it to the other options you have when choosing a shooter on XBOX360 to play online. It throws in just enough tactics by giving you nearly perfect maps. While there are a few dudds in the lineup, the maps they have given you to play on are generally well crafted, and made to utilize squad movement and tactics like flanking and decoy fire. You'll find the best gaming experience in the Ranked matches, as most of the player matches are filled with people with 2-3 people playing on the same xbox, and its restrictions are pretty harsh and tends to take away from it all. I suggest staying away from "Player Matches" unless you have friends over to play with. Ranked is the way to go and you get the true MP experience from it. Everyone is a step above what you'll find in non-ranked. They give you a few features like there is a point between dying and being alive that you get shot, but not enough to kill you totally and you roll around writhing in pain, at this point your teammates can heal you back to life if they can get there in time before you bleed out, or get finished off. It's a nice feature, and the fact that you don't have to pick a medic class to be able to do this is refreshing.
All in all the game experience is more than solid, its great.
