I'm about half-way through the game now, the only fun I've had yet is when I was able to control the UAV drone (Predator).
To be honest, just randomly running around and shooting criminal Brazilians is not that fun at all. The thing that made COD4 such a great single-player game was, in my opinion, the vast array of extra technology you were able to control - it added to the variety of the game and made it more than just running around shooting people.
