In Red Alert 3, the Soviets have been toying with time travel to try and save "Mother Russia," only to inadvertently cause a third world power, The Empire of the Rising Sun. In this alternate timeline, World War III has started between the Allies, Soviets and Empire. The game will feature a co-operative campaign mode.
EA also announced a PC-only beta of RA3 for anyone with a copy of C&C3: Kane's Wrath; details of the beta are expected this summer. Red Alert 3 is being developed by EA Los Angeles (Tiberium Wars, Battle for Middle-Earth). No release date was announced. While we applaud Tiberium Wars' gamepad-friendly controls, we're still crossing our fingers that the PS3 version supports keyboard and mouse.
