Arcade Gannon

Arcade Gannon is an ex-Enclave member, and currently one of the Followers of the Apocalypse, found in Hoover Dam in 2253.

Background
Gannon was an Enclave infantryman, coming from the saner part of the Enclave (mostly doctors and scientists) operating in the Midwestern United States. At some point, probably after the destruction of the Enclave Oil Rig, he deserted the Enclave and joined the Followers of the Apocalypse in Hoover Dam.

Interactions with the player character
He was supposed to be a joinable companion, specializing in Science and Repair.

In Burham Springs, he could identify the Poseidon Energy logos denoting the AGRICOLA lab.

Appearances
Gannon was going to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios. While the Denver design document mentions him as being in Hoover Dam, the Hoover Dam design document does not mention Gannon, which probably indicates that he was added into the game after the latter was written.
