Great Britain

Real world full name: United Kingdom of Great Britain and Northern Ireland.

An island nation in Europe far to the east of the core region/known world for the Fallout series. Before the Great War it was a wealthy country and most likely a nuclear power (like its real world counterpart). It was the leader of the states in both the normal Commonwealth and European Commonwealth. Allistair Tenpenny is known to have come from the United Kingdom before travelling across the Atlantic. No details are known about the state of the British Isles after the Great War. Except for the idea that Great Britain was bombed so much that the the country just sank underwater.

Official statements

 * Allistair Tenpenny came to the Capital Wasteland from Great Britain to seek his fortune, so that alone tells you that the U.K. was also hit in the war. And if he came to U.S. to succeed, that says a lot about how screwed up Europe must be. So we just allude, a little bit, to the state of the rest of the world. We like to leave a lot to the players' imaginations, and somebody like Tenpenny serves as a catalyst for those thoughts. - Emil Pagliarulo
