X-COM

In 1999, Unidentified Flying Objects (UFOs) started appearing with disturbing regularity in the night skies. Reports of violent human abductions and horrific experimentation struck terror into the hearts of millions. The mass public hysteria that ensued only served to expose Earth's impotence against a vastly superior technology.

Many countries attempted to deal independently with the aliens. In August 1998, Japan established an anti-alien combat force; the Kiryu-Kai. Equipped with Japanese-made fighter aircraft, the Kiryu-Kai certainly looked like a powerful force. However, after 5 months of expensive operations they had yet to intercept their first UFO. The lesson was clear: this was a worldwide problem which could not be dealt with by individual countries.

On December 11, 1998, representatives from the worlds most economically powerful countries gathered secretly in Geneva. After much debate, the decision was made to establish a covert independent body to combat, investigate and defeat the alien threat. This organization would be equipped with the worlds finest pilots, soldiers, scientists and engineers, working together as one multi-national force.

This organization was named the Extraterrestrial Combat Unit.

After several years of operation culminating in the Cydonia mission X-COM was officially disbanded.

However in 2040 X-Com was back on the road at the Second Alien War against some underwater aliens. see TFTD for more info.
