There’s really only one weapon you need to kill everything in Fallout 4… The Fat Man. For those unaware, this gun shoots mini-nukes. It’s awesome. And YouTuber ZaziNombies has recreated the weapon in LEGO form. Look out, Deathclaws. This 1:1 scale replica of the Fat Man from Fallout 4 is built from 2,500 LEGO bricks and measures 4-feet in length.
