Fortnite saw the inception of the vending machines back in 2018 but they fell out of fashion. However, back in the last season, Fortnite saw these machines return.
There are two types of vending machines that you will find in the game. The first being a mending machine. This machine sells all health and shield related items.
The second is the Weapon-O-Matic machine. These machines sell weapons in exchange for gold. Interestingly enough, there a lot of Weapon-O-Matics on the island. So here's a guide that will help you locate all of these weapons with ease.
Fortnite Season 8 Weapon-O-Matic locations
Unlike the mending machines, that could be found near gas stations, the Weapon-O-Matic machines are spread out all over the island. And they are way more in number when compared to the mending machines.
That being said, the map below will help you locate these machines with ease.
That being said, other than Holly Hatchery, almost every other POI on Fortnite island has a Weapon-O-Matic machine. And in some cases, you may also find two such machines at one location, as is the case with Steamy Stacks.
But remember, buying weapons from a machine requires gold. So make sure you stock up a lot on gold before you try purchasing weapons from these machines.
Other than that, you can also buy weapons from NPCs too.
