If you’ve been saving your hard-earned dough throughout the game, you can walk away immediately ready to slay anyone who crosses your path. This vendor sells guns and has the Splattercannon for a little over 10,000 Caps (this can vary depending on your build and perks).
When you reach Nuka-Town, USA, right after completing the Gauntlet, head on over to the market and locate Aaron. To make this weapon seem even sweeter, you can actually get it pretty early on in the expansion as long as you have the funds necessary. Every consecutive hit on an enemy does an increased amount of damage, meaning you can tear through most enemies with ease. This auto-rifle puts other Fallout 4 rifles to shame thanks to its Furious Legendary Perk, solid accuracy, and top-notch fire rate.
The Splattercannon may possibly be the most powerful weapon in the Nuka-World Fallout 4 expansion.
