Fallout 4 was the tentative sequel to Black Isle Studios' canceled second iteration of Fallout 3, codenamed Van Buren; it would have been developed by Black Isle Studios and published by Interplay Entertainment.


The game never proceeded past the conceptual phase due to the cancelation of its predecessor on December 8, 2003 and licensing of the Fallout series being sold to Bethesda Softworks in 2004.


Van Buren developers intended to focus on Caesar's Legion in the game, and the presence of Legion slavers in Denver was meant to hint at their inclusion in the sequel.[Non-canon 1] Much of the Legion content had actually been planned for Van Buren itself, but the team realized the project was too ambitious and pushed it to the sequel.[Non-game 1]



  1. Interview with Sean K Reynolds on Duck and Cover (Archived): "6. What parts of the country does the player get to explore first hand in Van Buren? Also, would there be any references to other part'sIn-game spelling, punctuation and/or grammar of the country, both those seen in FO/FO2 and other unseen parts?
    It takes place in the American southwest (Arizona, Nevada, Colorado, Utah) ... the westernmost sites on the game map are the easternmost borders of NCR, and problems with NCR have a lot to do with what's going on in the game. There are references to the midwest (for a while there was a significant faction from the midwest in the game, but when we realized the size and story had gotten too big we cut them out but left some links in to make an easier transition to FO4). In fact, one of the links is there because of the radioactive twisters Cassidy mentions in FO2."


  1. Denver design documents, page 9: "The guys from Caesar's legion are a mystery. What are they up to? If you're allied with the Blackfoots you have an in with them, but they mainly want to keep away from the 'primitives and assholes' who live in this part of the continent. You can find out a little bit about them and get some hints about the direction of the next game in the series."
