11. The Return Of The Aliens
https://www.youtube.com/watch?v=ItvtkW94v2M Fallout 3's Mothership Zeta alien crash site was a solid continuation of where the other two games left off, each producing some brilliant 'WTF' moments that got everyone thinking as to the wider ramifications of whether or not Bethesda would eventually take the franchise to the stars and back. Well, F4 has the return of a very similar-looking orb-headed being, except this time you get to fight him for a few seconds, before getting your hands on the extremely powerful laser blaster he was carrying. A combination of the new loot and crafting systems will let you rework certain parts of the gun for maximum efficiency later on, but even its base stats are a fantastic find. According to
GameRevolution the location of the crash site can be randomised, leaving all of us to speculate if different aliens have different weapon loadouts, and if there's even more to be found after your first encounter. Let us know in the comments what otherwordly beings you've come across!
