Red Alert 3 once again thrusts the gamer into the unknown territory of an alternate history. The Russians, unhappy with the fall of the Berlin wall and their ever dwindling power, contrive to regain their former supremacy. Realizing that democracy is on the rise and not so easily beaten, they use Einstein's own time travel technology to go back in time and kill Einstein before he can tamper with the timelines and give the west the upper hand.
But something goes wrong. Instead of ending up the dominant military power in the world, they inadvertently create a third world power, unleashing a third faction onto Red Alert's battlefield: The Empire of the Rising Sun.
