Within the original narrative of Cybershock, which includes both the manga and the game, the protagonist—who is intended to be portrayed by the player—sets out on their quest armed with The VKX MK1, a combat-ready type introduced in the early 2030s, coinciding with the abrupt advent of the zombie virus. The VKX quadrotor drone was developed as a versatile industrial drone capable of performing a variety of jobs and missions. However, amid the chaos that followed the zombie virus spread, brilliant police officers and firefighters began to improvise by retrofitting drones with weaponry such as machine guns and grenade launchers. This led to the development of the VKX MK1 (prototype).
