Vault 118 Vault 118 is an unfinished Vault - Tec vault located on the Island in 2287 , accessed by going through Cliff ' s Edge Hotel . Background . The vault was intended to encompass two wings under one overseer , one to house members of the highest class of society ( Hollywood actors , business tycoons , scientists , artists , etc . ) , while the other to house the lower classes . The second wing was never finished and while the vault was used as a fallout shelter , the vault experiment never started . Vault 118 was primarily built and intended for housing upper and lower class citizens , in order to test what would happen when the two groups clashed . However , after the luxury wing was completed , funding for the project stopped and construction for the lower class wing was halted . Apart from a few scientists , the only other Vault - Tec employee was the overseer , with all the servants being robots , in order to minimize conflict on the experiment . After the vault was closed , Bert Riggs , a former scientist at General Atomics International proposed to move the inhabitants ' brains into robobrains in order to survive longer . All inhabitants and senior Vault - Tec staff agreed to this , against the protests of the overseer . Shortly after , the Overseer was driven mad by the robobrains and committed suicide . Layout . Upon entering the lower level of the hotel , the vault entrance will be found with the door sealed . Activating the door controls will trigger a conversation with Maxwell , who asks the player if they are the detective he requested . Answering yes will open the door . Maxwell will be waiting for the player in the front entrance . If Pearl is present due to recruiting the player as the detective and escorting the player , she will interject and answer instead . Going right leads to an extremely lavish hallway with a large fountain . Straight from the fountain leads to the ballroom , where the murder took place . Right from the fountain goes to either Pearl ' s shop on the right , or residences ahead . This residence hall contains a room full of display cases containing various items attributed to Ezra Parker ' s pre - war exploits , which leads to Ezra Parker ' s bedroom ; Keith and Gilda ' s stage , with their adjoining bedrooms ; and the classroom , which functions as Bert Riggs ' lab and contains several tools and a chemistry station . A staircase at the back of the hall leads to the upper level . Going left from the fountain , the player can either go left into the security office housing four protectron charging stations , a desk , and a staircase to the upper level , or right leading to another hall of residences . This hall houses Santiago Avida ' s art gallery , next to it is a decrepit bedroom that appears to belong to Santiago , though it appears he never uses it . Across the hall is Julianna and Bert ' s room ( filled to the brim with assorted junk ) and at the end of the hall is the showers . Beyond the showers is the beach , with sand and an artificial lake . Going left from the main entrance is a short hallway filled with trash that leads to a sort of parking garage . A Corvega is suspended from a crane surrounded by nine garage doors on either side , three doors to a level . The large vault elevator , similar to that of Vault 111 and seen on the surface outside the hotel , can be found here . A hole in the wall on the center garage , second level right side , leads to a small cave with a bulldozer and crates . Beyond that is another small room with a door blocked by crates . The upper level of the vault is in complete disrepair as opposed to the lower level . The overseer ' s office is found upstairs in the right corner of the ballroom . Inside , a desk takes up most of the main room and contains the skeleton of the overseer , which is wearing a Vault 118 jumpsuit , and the overseer ' s terminal next to him . Behind the desk is an entrance to the overseer ' s personal quarters , with a lavatory . The only other location upstairs is the Hydroponics lab , across the ballroom from the overseer ' s office . A variety of plants can be found here , as well as at least one Concierge attending them . Appearances . Vault 118 appears in the " Fallout 4 " add - on " Far Harbor " . Behind the scenes . The painting of the sailboat in the artificial beach may be a reference to the scene at the end of the film " " , where the titular character crashes a sailboat into the wall of an artificial ocean . Bugs . Upon leaving Vault 118 via the elevator , the player may get stuck within the elevator . Reloading a previous save might help , some report that attempting a fast travel plus a few minutes wait time in the elevator fix it . Hearing elevator music upon loading may be an indication that you are no longer trapped .
