Therefore, with so many questions to be answered, it seems only logical to include a new Zeta-esque DLC for the Fallout series.

We also know that they have extremely advanced weaponry which has made an appearance in Fallout 4. What, exactly, do we know about the aliens of the Fallout universe? We know that they are ponderous, beaming several generations of people for study into Mothership Zeta in the Fallout 3 add-on. Let's take a look at what we know - or rather, don't know. From the unknown nature of these creatures to the borderline unfinished story of Mothership Zeta to the Zetans' current existence in Fallout 4, the Commonwealth seems incredibly prepared to receive a hostile alien invasion in the months to come. (Or, more appropriately, Zetans.) I firmly believe that Fallout 4 will see the return of these hostile extraterrestrials in an upcoming piece of downloadable content. The fifth and final add-on for Fallout 3 introduced something that nobody saw coming: aliens. For Fallout 4 on the PlayStation 4, a GameFAQs message board topic titled 'Any sure way to trigger the alien ship crash?' The ship always crashes east by south-east of Oberland Station. Fallout 4 UFO crash is a random encounter. All companions comment on UFO crash landing.
