Don't get me wrong I think that the singleplayer campaign is great but but multiplayer is just dreadful.

The singleplayer campaign is a good one with several interesting moments but it is far too short and it took me about 5 hours to beat it one hard difficulty. However the Tier 1 mode gave me a few more hours of enjoyment before I finally decided to turn to the online multiplayer. I didn't get a kill in my first game and then I said to myself it was just a fluke since i was still getting used to the controls. When five games later I was getting my butt shoot off by some Tier 1 commander with an M16. I just said this is awful and I got the new Prince of Persia game for some mindless fun till Black Ops came out.
Overall this was a potential game of the year but the multiplayer difficulty is ramped up so much that unless you have no other games your likely to resell it in a week or so. This just my opinion rent it first and then decide if you like it.
