Zeta Reticuli is the supposed homeland of the Gray species, made famous after the Hill Abduction event on September 1961.Īliens do not feature highly in vanilla Fallout 3, with their only physical appearance being just a dead body beside the crashed UFO, but the Aliens feature prominently in the Mothership Zeta expansion pack.
Their scientific name, the Zetans, is most likely a reference to the star system Zeta Reticuli. They are based on the archetypal Gray alien, while their UFO and spacesuits are based off of the retrofuturist chic of the 1950's.
Aliens appear in all of the HD Fallout games, featuring as an enemy that have the unique Alien Blaster equipped.
