Had the game for a week now, and as i have done with all COD games, i played through the campaign before playing online. I must say i've always enjoyed the COD campaign modes but this years campaign has a number of floors and irritations.
Firstly, and this isnt a constant problem, but at times the AI of the enemy and your teamates can be utterly ridiculous. I mean i've had enemies standing behind me and my team, not shooting. I've had enemy shooting at someone 10 meters away, when im standing about a meter away from them. To put simply, you'll see a lot of strange things with the AI in this game. Although annoying at times, it isnt really a major problem.
What suprised me this year is how dull the missions are. I've always liked the variation in previous COD's. What with sniper missions, stealth missions etc. But this year, sniper and stealth missions are few and far between, and generally not that fun. They have added in the use of helicopter based missions, and the control of a spy plane. But to be honest, i found it all a bit boring. This years campaign is one of wave after wave of destruction at times. As a result, for me at least it became a bit monotinous.
A further problem i found with the campaign was the ridiculous way in which its set out. You spend most of you time flashing back to this room, where you are being interrogated by a man whose voice becomes immensely annoying. It came to the point where i often lost the will to listen.
Multiplayer is much the same as previous renditions, despite a few additions. It seems the majority of the focus has been placed on customisation, which to me isnt really important.
All in all its a decent game, but single player isnt even worth playing this year in my opinion.
