Fallout: Ranking Every Vault From Least To Most Horrifying
23. Vault 15 - Closed For 50 Years With People With Radically Diverse Ideologies
Vault 15, present in both Fallout 1 and Fallout 2, was primed and ready to explode into a powder keg of internal strife.
However, despite Vault-Tech purposefully filling the Vault full of people who were of massively different ideologies and cultures, for the most part they lived together pretty well for some time.
The only major event happened when there was some form of disagreement between the dwellers, and lots of dwellers decided to open the door, steal all of the equipment inside (including a very valuable GECK unit) and travel off to make their own lives in different communities. A small group stayed behind until the Vault was finally raided by the local bandits, and it was since left abandoned.
