Vault 101 Revolt The Vault 101 Revolt was a conflict between the security force of Vault 101 and rebels wishing to open the vault and establish links with the outside world , beginning on August 17th , 2277 , and continuing until an unknown date that year . Prelude . On the morning of August 17th , James escaped from the vault , and attempted to bring Jonas Palmer along with him , who was brutally murdered by security in the process . The overseer , Alphonse Almodovar , then ordered the vault into lockdown , with citizens required to remain in their quarters , and using emergency lighting only , due to a massive radroach attack . The overseer ordered that James ' child be arrested on suspicion of co - operating with James ' plans . His daughter , Amata reached the Lone Wanderer in time , and awoke them to warn them of the situation . A plan was drawn out to break into the overseer ' s office and traverse a secret tunnel leading to the vault entrance . After fighting several members of the security force , the Lone Wanderer reached the jail cell sector of the vault atrium . Through a window , the overseer was seen with Officer Steve Mack interrogating his own daughter for information on the Lone Wanderer . The Lone Wanderer could have entered the room and fought them off , allowing Amata to escape , or the Lone Wanderer could simply have walked away and left the situation . Alternatively , Amata could have killed Mack with a 10mm pistol and threatened her father with it . Regardless , the Lone Wanderer then escaped Vault 101 . Revolt . During the time between the Lone Wanderer ' s departure and the Capture of Project Purity , the situation in the vault deteriorated , and civil relations broke down . Families and friends went against one another , and the vault was split in two : one side wanting to re - open the vault and establish relations and trading links with the outside world , and the other wanting to revert to the previous state . Amata established the rebels alongside Edwin Brotch , which contained the majority of the vault ' s youth . Dependent on the events of the first day of the revolt , the vault ' s leader would have been either Alphonse Almodovar , or Allen Mack . After days of fighting and sprints for the vault entrance , the rebels were pushed back into the corridor containing the clinic and classroom , where they made a final stand . Brotch was later arrested by security for suspicion of attempting to lead a run for the vault door . Several rogue members of security then began to secretly draw up plans to assault the rebel stronghold , with the objective of possibly killing a youth or two if required in order to make the rest fall back into line and revert the vault back to its previous state before James ' departure . In addition , the Enclave contacted the overseer , offering amnesty and an official connection with the United States government , in exchange for free access to the vault and its database . They were denied . Amata then sent out a distress radio signal into the surrounding area of the vault , going as far as the neighbouring town of Megaton , calling for the Lone Wanderer to return and solve the situation . When they returned , they had the choice of either convincing the rebellion to step down and cease their ideals , or to side with the rebellion and either kill or convince the overseer otherwise . Alternatively , the vault ' s water chip could have been purged and sabotaged , forcing the vault to be abandoned forever . Aftermath . Depending on the actions of the Lone Wanderer , if the rebels were supported , Amata would have become the new overseer , the vault would have been re - opened , and citizens such as Susie Mack would venture out into the wasteland for trading . If the rest of the vault was supported , the rebels would have stepped down and the vault reverted to its previous state . However , this would doom the vault , since they have no genetic stock or diversity remaining to last for another generation . If the vault ' s water chip was purged and destroyed , the entire vault would have been evacuated , and the corpses of dead Vault 101 residents would be found dotted around the wasteland , and Amata would have been interrogated for the vault ' s location by the Enclave , and then executed . Appearances . The Vault 101 Revolt appears only in " Fallout 3 " .
