With the development of the times quite rapidly, a group of youths or usually called Hyugai in the village of Veganecro created an innovation in the form of a massacre car which was considered very unusual for military use. However, at the end of 2019, there was a scary virus that spread very rapidly. This virus can change normal human behavior into a highly virulent species and attack humans and each other. By the time a group of village youths were about to finish their car, some of their neighbors had already been infected with this virus. The increasingly complicated situation forced them to immediately board the car and save themselves by crashing one by one the Necromach in front of them. With Hyugai's Propellant gas works to provide acceleration to the car and as an Active Necromach exterminator when approached, help Hyugai to survive from the Necromach!
