Even thoughFallout 4is atreasure trove of unusual weapons, not every gun can be on par with Fat Man. Being a hand variation of the miniature nuclear launcher, this weapon will show you what real fireworks are like and make you fall in love with big explosions in the game. With just one projectile (or more with MIRV modification), this weapon will allow you to fire a mini-nuclear bullet to create giant explosions and deal tons of damage in a decent area, which looks quite impressive.
The good news is that Fat Man is relatively easy to get, as it can be found in many places. But to simplify the task, we will tell you about the most quickly accessible locations.

Where To Find the Fat Man in Fallout 4
Since the Fat Man is a simple variation of its weapon type and is less powerful than the Nuka-Nuke Launcher or Big Boy, it is found relatively frequently in several locations. But don’t take its inferior status as a weakness, because this weapon still has incredible explosive power and can kill almost anyone. Of course, you will have to practice to learn how to shoot with it since the parabolic trajectory of the projectile is not that intuitive, but first, you should find at least one such gun.
It is worth noting that you will not be able to buy Fat Man fromFallout 4merchants, so the only way toget this weaponis to find it or take it from the previous owner. So here are some of the simplest locations:

These are just some of the easiest locations where you may find Fat Man. In truth, there are about 25 ofthese guns on the game map, so with a high degree of probability, you can find several simply by following the plot and exploring the game world. And as soon as you get at least one Fat Man, you can shoot powerful mini-nuclear shells that explode a large area and deal 450 base damage to anyone unlucky enough to get attacked. Of course, over time, such explosions will become not that impressive for you, and in this case, it is worth your time to find a Nuka-Nuke Launcher or Big Boy.
