Fallout: Ranking Every Vault From Least To Most Horrifying
8. Vault 95 - Populated By Drug Addicts, Primed To Release Drugs After Five Years
There's a real problem in the universe of Fallout with people abusing 'chems', AKA drugs. In Fallout 4, Vault 95 was designed to be completely populated by those suffering this addiction.
Of course the difficulties of living underground without a steady supply of drugs were challenging for all of the residents, but what happened after five years is even more screwed up.
Vault-Tec's experiment in this case was trying to see what would happen if former addicts were given access to a sudden copious supply of drugs. As such, after half a decade had passed a secret agent in the population would open up a large-size hidden supply of chems, and document what happened afterwards.
As the chems were revealed, any progress made to live together in harmony was destroyed overnight. Violence erupted across the Vault, the chems were taken and many residents immediately fell off the wagon. Due to the bodies inside, it's believed that most of the population then perished either through violent means or as a result of their addictions.
