In a 2009 interview with "Engadget", while talking about a possible "Fallout" game for iOS, Bethesda's Todd Howard said that the world of "Fallout" was "unique enough that it could translate to any platform", revealing that several designs of an iOS "Fallout" game were pitched and rejected. On November 5, 2009 John Carmack, who at that time worked for id Software, said that while it was nothing official yet, he had an internal proof of concept made for a "Fallout" iPhone game. Carmack said that he would likely be personally involved in making the game, although at the time he was working on other projects. He added that "at the very least I'm going to be providing code."
