If you only go by what is presented in Fallout 2, it's simple to assume that the enemies that look similar to xenomorphs from Alien, and labeled Alien, are in fact aliens.
The only time I had ever seen anything that claimed different was in the Fallout Bible, and even if Avellone insists its canon, IMO it's not, because that explanation wasn't used in the game at any point. If you play Fallout 2, and never read the Fallout bible, you would never come to the conclusion that they were created by the military.
Now, does this mean Bethesda is making the right call by overtly making an alien presence known in such blatant way? No. Again, they totally do not understand the concept of Fallout's "retro-future". They seem to think that any 50's sci-fi B-Movie fits in perfectly with the Fallout world, and that's just idiotic.
