A very good single player game.
The gameplay is still the same as well as the graphics with few enhancements. The user interface has been improve visually and gameplay's system is also been changed to bring new features to the game.
The soviets and allied gets new and powerful additions to their arsenal, which creates a new style that force old players to adjust their strategy.
A new faction has been added. These new units are far different from the units of Allied and Soviets, which is composed of very unusual and weird units and structures. Unfortunately no campaign available but it is still playable in other campaigns.
There are two new campaigns for both the Soviets and the Allies, both have weird missions such as traveling through time and going to the moon.
Because of all the additions to the game that it creates such imbalance which ruins the multiplayer competition. The new faction is so powerful that it creates mockery to the others.
Highly recommended if you want to follow up the single player game, but not advisable to the multiplayer mode.
