where does fallout 1 take place

Fallout 1 takes place in a post‑apocalyptic version of southern California, in a region known in the series’ lore as New California.
Key details about the setting
- The game is set in the mid‑22nd century, after the Great War of 2077 devastated the United States.
- Your home is Vault 13, described as being beneath the mountains of southern California.
- Over the course of the story, you roam a stretch of the ruined West Coast often referred to as New California, which includes settlements like Shady Sands, Junktown, the Hub, and Necropolis (built in the ruins of Bakersfield).
- In fan and in‑game terminology, the broader Fallout 1 (and 2) area is called New California, and some fans also refer to it as the “core region” of the Fallout universe.
In short, if someone asks “where does Fallout 1 take place,” the precise answer is: a post‑nuclear southern California wasteland, canonically called New California.
