2. Forced Evolutionary Virus – Fallout
FEV is largely responsible for a large number of mutations in the world of Fallout, which wasn’t—contrary to popular belief—caused by simple radiation. Originally known as the Pan-Immunity Viron Project, FEV was a pre-nuclear war research effort to give the United States an edge in their war effort against China.
In the post-apocalyptic world, FEV was harnessed by an individual named Richard Grey—also known as the Master—to create his army of super mutants, as well as a host of other bizarre monstrosities that inhabit the Wasteland.
