Only a handful of the original design documents for the Fallout games have been released. Three such documents for the first two games were released by Chris Avellone by way of the Fallout Bible, while the Van Buren designed docs were leaked and released at No Mutants Allowed in 2005. A petition to Bethesda Softworks was also sent, requesting the release of the Fallout and Fallout 2 design documents.

Christine Royce, Alkaya, Job, Xian, the Hanged Man, Eddie “Crazy Horse” Galenski and his “wife,” Helen Wheels, Gen. Coleridge, Capt. Davidson, Lt. Pierce, Maj.
