In the new era of 89347, the Alliance was formed and human civilization entered peace. However, the good life did not last long. A virus that was only transmitted between animals - "Eternal Life" changed everything. Not only did the animals become bloodthirsty, powerful, and brutal, they also had the ability to not be afraid of any gunshot wounds. With the ability to self-heal, normally docile pets extend their claws to their owners. Ferocious beasts destroy human cities. In the face of mutated animals, human resistance appears weak. After paying a heavy price, the Alliance's rescue was belatedly arrived, but things have gotten out of control...
