The premise of this project is that taipei becomes the battlefield between china and the US. US forces deploy their new combat-drones in the front lines for the first time. They are a secret project and are designed to camouflage as normal soldiers.
Course war in the future, or even today, would not really be fought in the streets of a major city like that, but hey, it looks cool in a game so :3
