|The following is based on Fallout Shelter or Fallout Shelter Online and some details might contradict canon.|
You do not need to fight in this quest. Vaultopolis is free loot and the vault dwellers give you free things. Some rooms are empty, while most give small rewards such as common weapons and caps, the room in which the vaultopolis dwellers live might contain better loot. The better loot is a random legendary weapon and some rare items.
- "Welcome, friends, to Vaultopolis!"
- "Many seek our sanctuary. Few find it. For we are... utopia!"
- "You are from a vault, no? May yours grow to be as amazing as ours."
- "You are welcome here always. Take these gifts, and our friendship."
