You’ll then hear the crash off in the distance, which you’ll have to locate. Once you’ve done the right set of missions you’ll hear something pop in the sky, your companion might respond, saying something like “did you just see that?” If you look up at the right time you should see the ship fly across the sky, leaving a trail behind. I’d recommend trying these if you still need to trigger the UFO crash. I personally hadn’t completed this mission, but I had just done some work for the Railroad, and finished the Silver Shroud intro quest.

Unfortunately we aren’t totally sure what those are at this time, but many are reporting that clearing out Vault 75 does it. The UFO will appear and crash only once you’ve completed certain missions. There seem to be a couple spots where this can happen, but by far the most common is right around Diamond City, so here’s how to find the crashed UFO and the Alien Blaster weapon that it brings.įirst up, this is not a totally random event. However, the interaction will usually consist of seeing their ship streak across the sky and hearing it crash at some unknown location. They are tough to find, only popping up at seemingly random points in the game, but play enough and eventually you’ll come upon one.

In case you didn’t play the wonderful Fallout 3 DLC, or haven’t been lucky enough to stumble upon them before, here’s some info for you: there are aliens in Fallout 4.
