About this creation
It's the end of WW3. The war itself was more of a slaughter. The only weapons used were nuclear bombs, and now, the world is covered with dust and nuclear waste and the sun is covered by dusty clouds, so the temperatures dropped a great deal... A so-called "nuclear winter" has taken place... People try to survive and rebuild, inventing all new kinds of technology.
