Fortnite Battle Royale Vending Machines is something that we have been asking ourself as what you can do with them. Vending machines at this moment have nothing no use but is something that Epic might be adding in the future maybe as a consumable vending machine where you can use it at one time for boosting you and giving you that extra boost that you may need. Maybe it could be that once you interact with them you will get the consumable.
Even though epic has not come out and advice the community what their plan is for the vending machines but is something that we should be looking forward to. Let me know what you think about the Fortnite Battle Royale Vending Machines as a possible use for boost.
