Vault 118

This area is populated by robots. The items inside are owned so taking them will be counted as stealing. As soon as you enter it, the quest Brain Dead will become available. There are some areas which you can freely loot the items so be mindful of the item's color before picking it up. There are no notable items or treasures to be picked up here, aside from the unique baseball bat (Fencebuster) that you can get from the quest or buying the unique hat from Pearl.

Pearl is the shopkeeper of the vault. She sells one unique headgear (The Dapper Gent) and a wide variety of ammo and components. Mr. Parker's room has several items you can take freely, especially those inside the display cases. There's also a bed that you can use freely. The classroom has a chem station.
