Alien (Fallout 4)

The alien is an extraterrestrial being found in the Commonwealth in the 23rd century. It can can be located in a cave near the UFO crash site.

Biology
The alien appears as a humanoid creature roughly the height of an average human. It possesses four limbs: two arms which end in three-fingered hands with opposable (or at least prehensile) thumbs and two legs whose digits cannot yet be discerned. The alien has a large head that features two pitch-black eyes, pointed ears, a flat nose with two nostrils and a mouth with nine-pointed teeth. The alien's skin is a pale yellowish-green hue with dark splotches scattered about.

When killed with a headshot, the creature's green-colored brain matter can be seen going airborne, leaving roughly half of its cranium exposed. An unidentified blue-colored anatomical component is seen when its head or extremities are damaged. The alien is apparently capable of breathing within the earth's atmosphere. When fresh, the alien's blood appears to be a light green, becoming darker as it dries, similar to human blood.

Gameplay attributes
The alien lies injured in the cave, and will not engage the Sole Survivor or any followers unless approached. He is extremely weak and will die easily.

Locations

 * The only alien that appears in the base game in the Commonwealth in 2287 is the survivor of a crash landing just to the east of Oberland station. The alien is in an unmarked cave just north of the crash site. If the alien is targeted in V.A.T.S., the display will show that its right leg is crippled. On sight, the alien will immediately attack the Sole Survivor. If killed, its body can be looted for an alien blaster pistol and 295-500 alien blaster rounds. Next to the alien is a human skeleton and a ham radio that is the source of the garbled radio beacon.
 * Over the Moon - A UFO with aliens can be downed near the Nuka-World transit center.
