Warning: Spoilers for Fallout season 1

Summary

• Fallout TV series reveals only a glimpse of the vast network of over 100 vaults that exist in its universe beyond California.
• Vaults play a crucial role in Fallout's narrative, as seen in the show's focus on Lucy coming from Vault 33 and its interconnected nature.
• Consistent with the games, Fallout series confirms the existence of 120 canonical vaults, each with its own unique purpose and dark secrets.

The place where Lucy grew up in Fallout's timeline. Not unlike the video games, Prime Video's TV adaptation of Fallout makes the vaults central to the show's narrative.

Since each Fallout game is set in a different location, players typically get to explore the vaults found in those specific regions. As for the series, Fallout takes place in California, a place that hosts several vaults of its own. In addition to exploring new vaults in the franchise, the show also sheds light on just how many vaults exist in the world outside California's borders.

The Fallout Show Confirms There Are Over 100 Vaults

Lucy is from Vault 33.

One of the three protagonists in Fallout's cast of characters, Lucy is a vault-dweller from Vault 33, a vault located underneath what used to be Santa Monica, California prior to the apocalypse. Vault 33 is connected directly to two other vaults, Vault 31 and Vault 32. Whereas the other two housed typical Vault Dwellers, Vault 31 was the place where Vault-Tec secretly stored its most powerful in cryo chambers. Also in the general area is Vault 4, a place that was ultimately taken over by the people the Vault Dwellers had performed experiments on. And as the Fallout season 1 finale confirmed, these are only four out of more than a hundred.

Flashbacks to the past revealed a meeting in which Barb Howard noted that Vault-Tec has constructed more than 100 vaults. A map revealed locations spread almost evenly across the United States. The conversation revealed that the vaults were divided up among the various power players within Vault-Tec and other established corporations like Big MT and Rob-Co. It was also during this meeting that they discussed plans to interconnect 31, 32, and 33, which was apparently all for the benefit of the people locked away in Vault 31.

How Many Vaults Are There In The Fallout Games?

120 canonical vaults are known to exist in the Fallout games.

What was established in the show matches up well with the games, which makes sense, considering that they exist in the same canon. The Fallout games have 120 canonical vaults, each of which serves a specific and unique purpose to their respective games. Several can be found in games like Fallout 3, Fallout: New Vegas, Fallout 4, and Fallout 76. Like the situation with Lucy, the games traditionally begin with its protagonist leaving a vault, with Fallout 3, for example, starting out in Vault 101. Similar to what happened in the show, players soon discover that nearly every vault plays host to some sort of sinister activity orchestrated by Vault-Tec.
