Chernobyl murdered during the Nazi occupation of 1941–44. Twenty years later, the area was chosen as the site of the first nuclear power station to be built on Ukrainian soil. The Duga over-the-horizon radar array, several miles outside of Chernobyl, was the origin of the Russian Woodpecker; it was designed as part of an anti-ballistic missile early warning radar network. With the dissolution of the Soviet Union in 1991, Chernobyl remained part of Ukraine. On 26 April 1986, Reactor No. 4 at the Chernobyl Nuclear Power Plant exploded after tests were done on the reactor improperly and the operators lost control.

It encompasses roughly 30 square kilometers and features a slice of Chernobyl extending south from Chernobyl Nuclear Power Plant; geographical changes for artistic license include moving the city of Pripyat into this area (it is actually to the north-west of the power station), although the city itself is directly modeled on its real-life counterpart,
