I have played all the Call of duty games, but this one has, I think, the shortest campaign ever. You play different special forces guys and you shoot down enemies all around Europe. You pursue Makarov, the main perpetrator, a terrorist and for that you use tons of bullets and grenades. You kill like Rambo all the way.
Funny thing your mates don't ever die in a firefight.
The graphics is beautiful, the music entertaining and the guns sound natural enough.
Sadly, it has such a short campaign like all modern shooters have.
