The most realistic of them all.
The graphics are improved quite well. Now parts fly like never before, it's much more fun to watch the battles.
The sounds sound really realistic in some points, nice job, still there are some sound that could use some improvements. the music plays rarely in the game.
the game still remains the same as the others CQC games, and there isn't anything new for the strategy. Still, they are on the right track.
Also some have unfair advantage, like China seems to be best of all them with all those Overlord tanks and Nuclear Missiles. So they could put them in a balanced way. It wouldn't hurt tough.
