Alien (Fallout: New Vegas)

Aliens are creatures found in the Mojave Wasteland in 2281.

Background
The three aliens can be found to the north of Horowitz farmstead and east of Brooks Tumbleweed Ranch. They crash landed due to technical difficulties. Although "aliens" is a general term, these particular aliens are the stereotypical "little green men" depicted in 1950's retro-futuristic renditions. They are an eerie green color, have an irregular shaped head, and stand roughly 4-5 feet tall. Their fingers are spongy digits with suction cup tips... which make it easier to snatch humans for twisted experiments.

Biology
They can apparently survive in an atmosphere composed of oxygen, nitrogen and carbon dioxide, like humans.

Gameplay attributes
These aliens are far more hardy than their cousins in Mothership Zeta. They wield superior weaponry, but have the same amount of hit points. The alien captain however has 16x more hitpoints than his Mothership Zeta counterpart.

Alien
Aliens appear only once in  Fallout: New Vegas and are identical in appearance to the aliens found in the Fallout 3 add-on Mothership Zeta. There are two aliens, both carrying tri-beam laser rifles.

Alien captain
The alien captain is a stronger variant of alien found in the Mojave Wasteland. Like the other aliens, he only appears if the player has the Wild Wasteland trait. The captain is noticeably taller and more human-like in stature than the other two aliens, and appropriately has much more HP. The aliens appear to scale to the player's level. The alien captain has the alien blaster in his inventory, but does not use it in combat against the player. If the captain is killed without the other aliens noticing you, they will not become hostile towards you, but cannot be talked to.

Appearances
Aliens appear in Fallout: New Vegas with the Wild Wasteland trait, and in the Fallout 3 add-on Mothership Zeta.
