I just feel that this has been rushed for Christmas. The game had all sorts of silly glitches, and (unlike CoD4) made the guns seemingly unbalanced. I may seem a bit harsh, but i think single shot rifles were the reason behind modding controllers (if it had been automatic rifles like in CoD4 or the SVT there would be less modded controllers) and having to get 25 kills for a sniper scope on a sniper just seems plain silly ^^
It's still a good game, bit of tweaking and patience tho and it could have simply a great recover of CoD4
