I have played it and its fucking epic! It's campaign is almost worth the money of buying it alone. The spec ops is also extremely fun and awesome. Also, the multiplayer is like MW2, In my case I like. Its even better than that though. Better graphics and guns sounds Its a good game and worth 60 bucks or in my case 77 dollars.
CoD always had a good campaign.
For the multiplayer side, I think it's like MW2. It's cool, but repetitive. If I buy it, it would be on PC and not when it lunch. Maybe in some months.
