Vault 92 Revolt The Vault 92 Revolt was a conflict between the security of Vault 92 , survivors of the white noise experiments , and the insane brutes transformed by the experiments , dubbed " crazies , " taking place in an unknown year . Prelude . Vault 92 was sealed on the day of the Great War , and the public objective of the vault was to preserve musical talent , by inviting many American classical musicians to stay . The governmental experimental purpose however , was to utilize white noise generators that implanted subconscious messages and orders into the minds of listeners . This was hoped to be able to create super soldiers that could follow any order whatsoever , take up to twenty bullets to die , and fight far more effectively than ordinary human s . This plan was fulfilled by the overseer , Richard Rubin , alone . He used the citizens as his puppets for the experiment . Professor John Malleus headed the experiments , none the wiser to the true nature of the research . The research came along smoothly , with subjects able to take simple commands , such as scratch their ear , or constantly fix their hair . However , a later experiment became a disaster . A subject named " V920717 " , the most promising test subject , dramatically transformed , and reacted differently to the white noise . He showed uncontrollable aggression and tore three citizens apart limb from limb , and the vault security spent 23 shots in taking him down . This was the fault of Rubin , who intentionally placed a different message , a combat suggestion , into the white noise he was subjected to , in order to see the results of the research for his own experiment , and expressed delight at the outcome . Revolt . Other subjects soon began exhibiting the same behavior as V920717 , and degenerated into raging , eviscerating monsters , dubbed " crazies " . Rubin controlled the situation by issuing a passphrase , which was " sanity is not statistical " , in order to reverse the crazies back to their previous state . Malleus begged Rubin multiple times to take the situation more seriously and take more control , to which he was ignored , and oblivious to Rubin ' s actions . Finally , the passphrase stopped working against the crazies , resulting in the overseer and security losing all control of the situation . Over 50 % of the vault ' s inhabitants became crazies . The survivors spread into chaos , with many running aimlessly around the vault , becoming trapped or killed , and others locking themselves in rooms to die where they wanted . One group , however , were plotting a sprint for the vault door . Whether they escaped or not is unknown , since skeletons can be seen around their dropped notes , however , the vault door was left open on the Lone Wanderer ' s arrival . Aftermath . Not much is known of the aftermath . Rubin ordered Malleus killed , however , once again , the outcome of this is unknown . The engineering team of the vault detected an issue in the walls of the reactor sector of the vault sometime before the experiments . The walls began cracking due to an underground body of water in the caves surrounding the vault . The engineers repaired the wall , but only temporarily , and they themselves stated that a more permanent solution would be needed sometime soon . Due to the revolt , this never occurred , and so the walls burst , the reactor sector was flooded waist - high , mirelurk s and bloatflies poured into the vault and made nests . Appearances . The Vault 92 Revolt is mentioned only in " Fallout 3 " .
