Bethesda's VP of public relations, Pete Hines, has confirmed with Edge Online
that the US, UK and Australian versions of Fallout 3
will be "identical" to one another. A reference to the real-world drug Morphine has been removed, explains Hines, to abide with each country's ratings and classification boards, replaced with "Med-X."
While "material promoting or encouraging proscribed drug use" has been replaced with more fictional drug references, Pete Hines tells Joystiq that "nothing else" has changed, including the over-the-top violence we've been enjoying in the screenshots. Full statement from Hines after the break.
