The alien captain is a stronger variant of alien found in the Mojave Wasteland. Like the other aliens, he only appears if the Wild Wasteland trait is active. 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. If the captain is killed without the other aliens noticing, they will not become hostile but cannot be talked to.
Aliens count as abominations, and as such can be scared away with a flare gun.
The alien captain will always appear hostile, however, the other two aliens will not be hostile unless the captain spots the Courier. If the captain is killed while one is hidden, the other two aliens will not turn hostile unless attacked; instead they will stand and look at the Courier silently, as they lack voices.
If an alien's torso explodes, pieces of flesh left will be oversized compared to the original body size. These body parts will also be red despite the original green color of the alien.
The alien captain almost always flees, while the other two aliens will assault the Courier with laser weapons. The captain will then enter combat with the Courier once his fellow aliens are killed.
The alien captain will not use the alien blaster against the Courier. He cannot equip it and will use a laser pistol instead.
Looking at the ship, it appears to be broken and there are many wires hanging out of the back. The ship also appears to hover as it moves up and down.
If the Courier does not have the Wild Wasteland trait, the aliens' spot will be occupied by mercenaries instead.
In some cases the Courier can find two weapons of the same type on one alien (this does not happen with the alien captain).
Companions often pick up the alien blaster before the Courier can. They should always check the inventory of their companions when trying to locate the alien blaster.
Aliens left alive will be hostile to any Viper gunslingers chasing the player from Horowitz farmstead.
