IllusionZero[Mr. Ater]

On the basis of the 9 Underground Entrances for the game content, combined with warriors and original two-weapon combos, this game is a single one-to-many adventure with ready sense of fighting. Energy can be collected by killing monsters. As long as energy is fully possessed, the role’s finishing moves can be launched.

The excavation, golden book, records the 9 entrances of the earth's core, where were originally guarded by 9 nations. Each nation has a weapon made of the energy of the earth's core based on atomic theory. These 9 weapons, which should be possessed by mixed-bloods, can kill promise breakers. One of the nations, Aryan, is called as the controller closest to the core. They are communicators between legendary monsters of different places and humans. Aryan nation considers that monsters and humans cannot exist in the same world, and therefore negotiates for building an underground world by means of their high technology. It could on the one hand, make monsters guard the energy of the earth's core, and on the other hand, provide humans an easy life.

As the resources of the earth were exhausted, in order to obtain more resources and technologies, people went deep into the 9 vestiges of the earth's core again for resource exploration. However, these further explorations violated the agreement between humans and legendary monsters of different places for generations. All the countries on the earth were occupied overnight, and humans were thereby forced to form a small-scale country site for self-protection.
