The last Fallout title was in built around New Vegas, the upcoming one, however, we hear is taking place in Boston.
An anonymous Reddit user who goes by the moniker Fallout4Boston, who had to create a new account on the aggregate site to protect his job, said that he had solid information on Bethesda’s plans for the next Fallout title.
“The rumors are true, Fallout 4 will take place in Boston. In case you haven’t heard, Bethesda has recently been scoping out and researching Boston. They also have a strong connection to MIT. I may or may not be an MIT employee. But that’s really all I can say for fear of losing my job,” he said.
“Apologies for the vagueness of this post. It’s not just my job that worries me, but also getting the f**k sued out of me. Bethesda’s contracts are basically full-proof [sic] so if they were to discover who I am, or rather, who I got this information from, a few people including myself could get into a lot of trouble,” he/she later added.
