Fallout: Mile High
The Colorado Wastelands are a member of the Four States Commonwealth. It is largely unexplored, but reports of Caesar’s Legion having captured Denver have been heard through the region in the past few years. Life is hard east of the Rockies, and aside from a rumored scientific research station in Boulder, not much has been built here since the Great War.
Vault 303 opened in 2282 after a mild social experiment concluded.
