A version for the Xbox 360 console was released in the U.S. on November 11. The PlayStation 3 version was delayed due to difficulties with the system's architecture. On January 21, 2009 EA officially announced Command & Conquer: Red Alert 3 - Ultimate Edition,the PS3 version which contains bonus material extra to that of the Xbox 360 and PC versions. The Ultimate Edition has been released on March 23, 2009. Also announced for a late March release is the Mac OS version, converted to that platform by TransGaming. The game forms a part of the Red Alert sub-series within the Command & Conquer series of games. In early January, EA Los Angeles announced a new addition to the game: Command & Conquer: Red Alert 3 – Uprising, a stand-alone single player expansion pack that was released for Windows in March 2009. It was offered via digital distribution.
The game is set in a parallel universe in which World War II never happened—in the original Red Alert, Albert Einstein travelled back in time and removed Hitler in the 1920s. After an Allied victory in Red Alert 2, the Soviet leaders travelled back in time and removed Albert Einstein in 1927, preventing the Allies from creating atomic weapons while the Soviet Union rose to power, battling the Allies in the 1950s. In this game, the Empire of the Rising Sun rises to power as a threat as well (an unintentional result of the Soviets' time travelling). All three factions are playable, with the main gameplay involving constructing a base, gathering resources, and training armies composed of land, sea, and airborne units to defeat other players. Each faction has a fully co-operative campaign, playable with an artificial intelligence partner or with another human player online. These campaigns follow a storyline, with specific mission objectives and unit restrictions applied. Unrestricted skirmish play against the computer and multiplayer via LAN or online is also available.
The game received mostly positive reviews, with reviewers citing the co-operative and multiplayer components as strengths, along with the enhanced role of naval combat compared to other real-time strategy games. Commonly cited weaknesses included aspects such as unit pathfinding.
