Remember the aliens from Fallout 3's Mothership Zeta DLC? There's a very similar looking alien in a random moment in Fallout 4. At some point in the game, usually after you complete a dungeon, your companion will say something like, "Did you just see that?" You cna look up and see the ship falling from the sky. Once you track it down, you can follow the green blood to find the injured alien. Take him out, and you'll get your hands on the Alien Blaster weapon.
