Fallout

Fallout is a game series set in a timeline in which Nuclear Power was used for not only war, but also for powering the world, and it's technology. Eventually, The Cold War broke out, but it was drastically worse, instead lasting until the 21st century. This tension was somewhat relieved thanks to Vaults, which were constructed, to officially keep people safe in the chance of Nuclear War, but secretly was dedicated to experimenting on people, While some vaults were Noble, most were horrifying experiments, whether it be to create super soldiers, see how long humanity can last in a vault, how long would it take to colonize Earth again, ect... The War eventually became Reality on October 23rd, 2077. This led to many events.
