The next Fallout has been announced, and no Bethesda didn’t suddenly decide to skip a few dozen numbers. Fallout 76 seems to be following New Vegas’ lead as a spin-off from the main Fallout series, with the 76 referring to Vault 76.
The thing is, this isn’t the first time we’ve heard about Vault 76, and what we know about this vault actually tells us where Fallout 76 will likely be set, its place in the Fallout timeline, and also reveals a surprising connection to the very first Fallout.
Vault 76 is mentioned in a few places outside of its debut teaser trailer. It’s listed on a Vault-Tec computer terminal in The Citadel in Fallout 3, discussed by the news announcer in the intro of Fallout 4, and named during an audio log in Fallout 3’s Mothership Zeta add-on. You can see all of those examples in the video at the top of the page, and that handful of references is full of solid info.
