Intro. In the year 2277, exactly 200 years after the Great War—a global conflict that occurred in 2077. This nuclear war was the greatest catastrophe in human history, fought between the world's superpowers (including the United States and the People's Republic of China, among others). After the war, it remained unclear which country launched the first bomb. Despite lasting only 2 hours, it is called "World War IV" because it utterly devastated most nations, with the majority of victims dying instantly during the bombings, while the rest suffered from genetic mutations, blood disorders, and skin diseases due to the radioactive fallout. Such survivors were commonly referred to as "Ghouls". The only ones who lived through the disaster were those who sought refuge in special underground shelters or Vaults before the war.
