Alien (Fallout 4)

Aliens are extraterrestrial beings found in the Commonwealth in the 23rd century. One can be located in a cave near the Crashed UFO.

Background
Currently the only alien that appears in the Commonwealth appears to be the survivor of a crash landing. If the Sole Survivor activates Relay Tower 1DL - 109 a radio signal will be discovered titled "Garbled Radio Beacon." If the Sole Survivor tunes their radio to the frequency they can travel east and the signal will resolve to a higher quality until the Sole Survivor discovers what appears to be a crashed alien vessel in a small wooded area. At the crash site a puddle of green liquid that appears to be alien blood can be seen. Upon further searching around the area of the crash site the Sole Survivor can discover a trail of the alien blood that leads to a nearby cave, wherein a single Alien enemy can be encountered.

The Alien will be sitting in a small alcove next to a human skeleton and a Ham Radio that appears to be tuned to the Garbled Radio Beacon. If the Alien detects the player it will become immediately hostile and attack with its Alien Blaster Pistol. Also of note, if the Alien is targeted in VATS, the individual limb health indicators will show that its right leg is crippled, presumably a result of its apparent crash landing. If the Alien is killed, its body can be looted for an Alien Blaster Pistol and Alien Blaster Rounds.

As of yet the origin and original intent of the Alien is unknown.
