In the year 1939, humanity was on the verge of destruction. Equipped with weapons of devastating power, a mysterious alien race, known as the Neuroi, began an invasion of the Earth, ravaging the planet, obliterating countries, and vanquishing human armies. To counter this seemingly unstoppable force, the world's powers united. A new device was produced, called the Striker Unit, capable of facing Neuroi technology.
