I figured I'd combined two of my favorite video games, Fallout and Kaiserreich, so here goes!
Logo for the video game series Fallout. The games in the series include Fallout (1997), Fallout 2 (1998), Fallout 3 (2008), Fallout: New Vegas (2010), Fallout 4 (2015) and Fallout 76 (2018).
Fallout is a video game series which takes place in an alternate-history world which diverged from real history in the aftermath of the Second Weltkrieg, when the transistor chip is never invented, leading to a world where the technology and culture of 1950s America, including the Red Scare and Black Scare, the fear of far-leftist and far-rightist infiltration of American society after the victory of President MacArthur's government in the Second Civil War, continues well into the 21st century and into the 2070s. Thus this leads to a world of more primitive computers, atomic powered cars, AI robots, among other things.
In regards to the history of the Fallout world, the KalterKrieg never ends and continues well into the 2070s. Nations such as the Russian State, the Danubian Federation, the Qing Empire, the Brazilian Empire, among others, also still exist into the 2070s. In 1969, the subdivisions of the United States are reorganized, with different states becoming parts of thirteen larger Commonwealths. In 2020, the Republic of France, Italy, Spain and Portugal united into the Western European Commonwealth, in an effort to act as a greater counter-weight to the German Empire and Mittleuropa. In 2022, Sweden, Norway and Denamrk united into the Empire of Scandinavia, with the King of Sweden as Emperor of Scandinavia. For the first decades of the 21st things are mostly normal throughout the ongoing KalterKrieg. However, all of this changes in 2052 when a "New Plague" arises, killing tens of thousands, and the worlds fossil fuels begin to dry up, leading to the Recourse Wars. With the German Empire and Mittleuropa, Western Europe, Danubia, Scandinavia and the United Kingdom dependent on oil imports from the Middle East, the five powers join together in the Grand Alliance and declare war on the Arabian Axis of Egypt, Saudi Arabia, Syria, Libya, Tunisia, Algeria, Morocco, Oman and Yemen. The Russian State, with the powers of Europe distracted, declares war on Iran, Kurdistan and Turkey. Meanwhile, smaller nations like Ireland, Serbia, Greece and Bulgaria, among others, go bankrupt. As a result of the Recourse Wars, the Council of Nations disbands on July 26, 2052. Soon afterwards, small scale nuclear exchanges occurred between the Grand Alliance and the Arabian Axis, leading to humanitarian crises. The war finally ends in 2060 after the oil wells in the Middle East all dry up. The Western European Commonwealth, the Empire of Scandinavia and the Danubian Federation then break up into numerous separatists and warring states. The German nations of Mittleuropa also begin to turn against and declare war on the German Empire.
As a result of the Recourse Wars, tensions increase between the United States of America and Kingdom of Canada, but things remain cordial between the two powers. However, in 2060, after years of political instability in the formerly Socialist and Syndicalist nation of Mexico, the United States invades their southern neighbor in an effort to ensure stability, but also to make use of the natural resources of Mexico. In 2066, with the oil fields of both the Russian State and the Qing Empire of China drying up, the Russian State and Qing Empire of China join up in an emergency alliance and invade the formerly-Russian territory and US State of Alaska, thus leading to the Russo-Sino-American War. The war last for many long years and sees the use of many new technologies, including Power Armor, Laser Weapons, Plasma Weapons, among others. In 2074, American power armor units, infantry and mechanized divisions are deployed to Siberia and a number of regions throughout southern China. During the war, Canada remains neutral but supports the United States through weapons, technology and volunteer divisions. Nevertheless, tensions begin to rise between the USA and Canada over the depletion of the Albertan Oil Fields and increasing American economic power over Canada. In 2075, the United States annexation of Mexico is complete, leading to resistance from much of the Mexican population. In an effort to "secure stability" within the Caribbean region, the United States launches mostly bloodless invasions and occupations of Central America, Costa Rica, Panama, Cuba, Haiti and the Dominican Republic, leading to protests from Canada and the Caribbean Federation.
In January, 2077, the last Russian and Chinese forces are expelled from Alaska, leading to celebrations throughout the United States. Meanwhile, the United States continues to occupy much of Siberia and Southern China. Thus, the war continues. Finally, on the morning of October 23, 2077, at 9:42 AM EST, nuclear strikes from atomic bombs, either Russian or Chinese, are launched over New York City and Philadelphia. In retaliation, the United States launches nuclear weapons against numerous cities in both Russia and China. Five minutes later at 9:47 EST, Washington DC and Boston are struck by atomic bombs. Nuclear exchanges then occur between the US and Canada. The Russian state then invades and launches nuclear weapons against the remnants of Mittleuropea, Danubia, Scandanavia and Western Europe, as well as the nations of the United Kingdom, Romania, Serbia, Bulgaria and Greece, leading to nuclear strikes again Russia by Germany, Austria, Sweden, France and the United Kingdom. France and Germany then launch nuclear weapons against each other, the same happening between many other nations. The Qing Empire also launches nuclear weapons against India, Japan, Korea, the Philippines and Insulandia, all allies of the United States. Australasia, where it is already early in the morning on October 24, 2077, is also struck by nuclear weapons. In South America, nuclear strikes occur between Brazil, Argentina, Peru and Gran Colombia. In Africa, nuclear exchanges occur between South Africa and numerous other nations. In the Middle East, nuclear exchanges occur between the Republic of Iran and the remnants of the Arabian Axis. Thus, the world is destroyed by a large-scale, world-wide nuclear war in the Third Weltkrieg, or what would come to be called by future generations as the Great War.
Not long before the Great War, a massive corporation known as Vault-Tec built a series of numbered vaults all throughout the United States of America, all in an effort to save a select number of Americans from a nuclear war, but also to conduct a series of often unethical social experiments upon these unknowing survivors.
Thus, the stage is set for a post-apocalyptic, 1950s-influenced America.
