Alien



While there is some evidence of the existence of Extra-Terrestial life forms, it is very scarce. Until the events of the Fallout 3 add-on, Mothership Zeta there was no record of direct contact between humanity and the creatures.

The Brotherhood of Steel and Shi have encountered the bodies of alien life forms or their spaceships, as did the pre-War United States government, which kept its alien specimens mostly in Area 51. By extension the Enclave and Brotherhood Outcasts also have access to alien technology; Alien Power Cells can be found at Fort Independence and in the armory of the Enclave's Mobile Base Crawler.

Crashed ships
Two alien ships are known to have crashed in the United States, with a possible third:
 * Alien Ship in California
 * Recon Craft Theta in Capital Wasteland (Fallout 3).
 * An alien ship can explode over the head of the Lone Wanderer in the Capital Wasteland during a special encounter although the cause of the catastrophe is unknown.
 * Possibly, you will discover a dead alien in a special encounter.

Alien technology

 * Alien Blaster - a weapon of alien origin.
 * Firelance - a unique variant of the Alien Blaster,(Fallout 3).
 * Alien Power Cell - the power source for the Alien Blaster (Fallout 3).
 * According to its own (potentially unreliable) records, the Skynet computer was created based partly on alien technology (Fallout 2

Appearances
