10 Terrifying Fallout Vaults You Wish You'd Never Opened

If there's one thing more synonymous with the Fallout series more than bottle caps and Nuka Colas it's Super Mutants. These massive day-glo brutes tower above the average human, and with the strength of a bomb they will batter and maim anything that crosses their paths.

For a long old while it was unclear how such beings came into existence. Many speculated they were just humans who had been warped by the cruel wasteland above, and they were right to some degree, because these were indeed people who had undergone horrible changes. The twist is that they were the result of the experiments taking place in Vault 87.

Here a team of scientists had the FEV or Forced Evolutionary Virus tested upon them in an effort to make a being capable of surviving the irradiated waste once known as Earth. The experiment worked, to a degree, manufacturing a hulking mass impervious to pain and sickness, but with the side effect of being violently aggressive.

After the paltry security team was wiped out, the experiments escaped. Yet if you thought this was all she wrote for the Vault, trust me it gets much worse. The FEV makes Super Mutants sterile, and if they want their race to continue they now capture other humans and mutate them against their will. Therefore Vault 87 is a horror show in every sense; dangerous, dilapidated and full of the cries of the unlucky.
