The year is 2140.After numerous wars and several environmental disasters, only two world powers remain; theUnited Civilized States (UCS) covering the American continent, Western Europe and North Africa, and the Eurasian Dynasty (ED)covering the coherent landmasses of Eastern Europe and Asia. The damage caused by the long wars led both world powers to evacuate the population to recently built underground cities.

Australia and most parts of Africa were sacrificed during the long wars, which lasted several decades. Highly toxic biological and chemical weapons were developed on these continents, leaving them so badly contaminated, that no human life can survive there. Not even the use of robots and machines is possible. The general opinion was that these continents would forever remain uninhabitable, and they were wiped from every map. Most of the world's population forgot that this land ever existed.

The UCS system is one of stochastocracy (coincidental rule). The population enjoys a lazy and decadent life. They live for their own enjoyment and let machines (so-called "Black-Tech"-robots) do all the necessary work. The population has no interest in politics, leaving the rulers to be chosen randomly using computers. The Eurasians are governed by the dictatorial Khan Dynasty. These days Tiao Zhan Zhe Khan (his name means Provocator of War) rules the ED.

Due to the environmental problems caused by the wars and the contamination of most parts of his country, the 34th Khan Yong Shi Khan (Brave Warrior) ordered the development of a technology to replace parts of the human body with mechanical parts, a way of reducing the population. Now, in the reign of the 37th Khan, these goals have been achieved. The population has been transformed into ascetic and extremely powerful androids. The "human" body now consists of rudimental organisms which support the brain and numerous mechanical components, which have been developed for specific android tasks. Population growth is controlled by using cerebral transfer to create new androids. An android's brain cells are used to clone a new body and the mechanical parts are built around it.

Natural resources are becoming scarce and have to be extracted above ground. There have been a number of small conflicts between the UCS and the ED, the last of which escalated and became a fierce and bitter war - the final world war. Only one side can win. This final war will decide who will get the last of the available natural resources and ultimately rule the world.
