it is the ending days of the 21st century. earth was militarizing continuously until the world war3 began. the world was devastated and may places were contaminated by weapons of mass destruction. the west was able to defeat the eastern nations, but the new rulers of the world weren't kind and didn't think about humanity or science, they only thought about power. the 22nd century has arrived people live in dark cities and some of them are hives filled with gangs and criminals.the ruling gangs have the help of politicians and these gangs serve them as their private armies.
