Seattle

Before the Great War, Seattle was a city in Washington State and then in the Northwest Commonwealth. One of its major landmarks is the Space Needle, which seems to have survived the War. Unlike the Core Region or the Capital Wasteland, Seattle is, at least in the winter, covered in snow.

Appearances
Seattle appears in a piece of concept art for Project V13 (Fallout Online), where the Space Needle is clearly visible. It is not known whether it will actually appear in-game.
