It has an expansion pack, Yuri's Revenge. RA2 has a more funny and cinematic style compared to its prequel and Tiberian Sun, but also better FMV acting. After he attacks America, President Dugan orders a full-scale retaliation, which fails because Yuri remotely disables the ICBM silos. Ever since an artificially psychic Yuri became his chief advisor, his relations with the US have deteriorated, and some signs have shown he is not acting in good faith. Its story, though continuing straight on from Red Alert's Allied campaign, makes no mention of GDI and instead has a puppet Soviet ruler called Romanov who has been installed by the Allies, who, though an aristocrat and a member of the communist party (which is actually an oxymoron), was an advocate of peace. Red Alert 2 is the sequel to the game Red Alert, though it has been officially designated as non-canon by Electronic Arts.
