Now the AI can attack each other and not just the player. Hotkeys and Interface changes added Observer Mode. RA2 now has an Observer Mode that allows one player to watch other player's games. This is particularly useful for Korean television shows and tournaments. There is a new checkbox at the top of the bunkers that players can check to observe games.
Dreadnaughts can now break bridges with missiles.
Now players can destroy a unit flying over an Iron Curtained building. If the player has a Cloning Vat, an Engineer, two infantry units, and a Tech Hospital, he will no longer get a complimentary unit out of his Cloning Vat for every unit healed. The edges of the Radar Screen are now visible. Also included is the Westwood endorsed configuration. The Desolator will no longer continue to shoot the ground over and over and keep building up radiation.
