For the released Fallout 4 from 2015 by Bethesda Softworks , see Fallout 4.

Fallout 4 was the tentative sequel to Black Isle Studios's 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 cancelation of its predecessor on December 8, 2003 and licensing of the Fallout property 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.[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.[2]


  1. Denver design document, 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."
