An expansion to Command & Conquer: Red Alert 3 that can be played without the original game. Uprising features additional campaigns for three factions: the Allies, the Soviets, and the Empire of the Rising Sun. The plot continues the events of Red Alert 3, making Allied victory in previous game canon.
The Soviet Union fights for its very existence because Allied corporation FutureTech is developing a weapon that can freeze time. Its leaders want to erase Soviet Russia from the history once and forever. The war in Allied-occupied Japan continues, as there are still pockets of resistance that Allies have to suppress, and there are two Russian generals taking over parts of the Empire. There's also a standalone campaign that reveals the origins of Yuriko Omega, a Japanese girl with psionic abilities, and follows her as she becomes a commando for the Empire, and later a prisoner of the Allies.
Unlike some of the previous games in the series, Red Alert 3 – Uprising allows no multiplayer modes, neither cooperative nor competitive.
