It is 2000 years after the nuclear war between the west and the USSR. After the nuclear fallout, survival was the only priority for humanity, just like its prehistory.

Now, humanity has recovered but the history of modern society has been lost. And now it's post-fallout historians' job to rediscover and study modern history. It's not very easy, just like modern historians struggling to understand ancient history.

You are a historian, in a ruined city that was inhabited before the nuclear fallout, studying for clues on how modern humans used to live.
