Command & Conquer Collision Course mod for C&C3: Tiberium Wars

In 1986, after the end of World War III, time travel was outlawed globally. The Allied Nations and the Soviet Union both signed pact eliminating use of time travel devices due to the imbalances it would cause the world. As a result, Einstein's Time Machine, that changed the tide of the war against the Soviets and Yuri's Army, was locked up tight in a Vault in Area 51, never to be touched again...

In 2047, Area 51 was deserted, as it sat deep in the Nevada Yellow Zone. The base was scavenged by Forgotten Mutants but the Vault remained untouched. Violent Ion Storms have recently been forming in the area due to the increasing amounts of Tiberium gas in the skies over Nevada. Nobody has any records how it happened, but a storm triggered the Time Machine to activate violently. Using old Chrono technology and highly unstable, the machine couldn't take the voltage running through it, far more voltage than what was used in San Francisco. A Chrono Vortex opened up, taking everything in the base into it. Fueled by the storm, the Vortex continued to grow until it was to the point where the whole planet was in its grasp. Distorted by time, Earth vanished, only for a moment...

Earth re-emerged, the Vortex merged the timelines of the past, all the events and wars fought over centuries suddenly started crossing over. Cyborgs were seen slaughtering Soviet's in New York, strange green crystals were overtaking Italy by the masses, Japan was showing signs of hostility toward nations across the globe, and high concentrations of signals in the upper atmosphere were being identified as spacecraft. Everything was out of place, nothing was right. Commander, welcome to the Collision Course Conflict. He who controls the past commands the future, He who commands the future, conquers the past...
