Command & Conquer: Red Alert 3

In Red Alert 3, the desperate leadership of a doomed Soviet Union
travels back in time to change history and restore the glory of Mother
Russia. The time travel mission goes awry, creating an alternate
timeline where technology has followed an entirely different
evolution, a new superpower has been thrust on to the world stage, and
World War III is raging. The Empire of the Rising Sun has risen in the
East, making World War III a three-way struggle between the Soviets,
the Allies, and the Empire with armies fielding wacky and wonderful
weapons and technologies like Tesla coils, heavily armed War Blimps,
teleportation, armored bears, intelligent dolphins, floating island
fortresses, and transforming tanks.

Red Alert 3 asks the question “What If?” What if every bizarre
research project and technology experiment for the last 70 years had
actually borne fruit? What if the Philadelphia Experiment, time travel
theory, teleportation, invisibility, Tesla technology, and a hundred
other intriguing research projects had all paid off and gone
mainstream? What if the Soviet Union survived and thrived; what would
it look like 10 years in the future? What if the Japanese Empire had
never fallen and instead became the ultimate high-tech military
superpower? The end result is an imaginative and playful vision of an
alternate future filled with possibility.
