Vulture (Fallout 3)

Vultures are creatures

Vultures survived the Great War and its many nuclear blasts, and can be seen flying above most settlements in the Capital Wasteland, such as Megaton, Temple of the Union, and Evergreen Mills. Vultures remain in the air indefinitely and will never land.

Behind the scenes
