War for Earth

The War for Earth started in 2025 when a race named "The Kyyn" came to invade for territorial expansion and resources.

The Kyyn had remorselessly murdered and pillaged half of the population on Earth. They caused many cultures and societies to collapse; they are now lost forever.

America had proposed a universal alliance with all remaining countries: Japan, Russia, China, the Middle East, and Australia. This was known as the UEA (United Earth Alliance). The UEA planned major strikes against the Kyyn fortifications planted in the now Kyyn occupied locations.

When the Kyyn thought there was no hope for the humans, the UEA fought back in the largest military battle in the course of history before the 3000's. Larger than D-day, all units were deployed at once to beat down the alien presence on Earth.

Humanity took back their home, until 3025 when the Great Landing occurred.
