The Rust Bucket is the name of the FREE promotional back bling cosmetic items for the game Fortnite Battle Royale. Cosmetic items do not provide any advantage or have any gameplay effect.
The Rust Bucket is a handy generator-like contraption that can be equipped in the back as a backpack. This handy device features what seems to be a license plate bolted on one side, some screws and pipes, and some random gizmos, valves, and switches. As a cosmetic item, this back device does not have any function and does not provide any benefit to the player.
This backpack can be acquired for free in the Item Shop for a limited time. The Item is free for purchase until April 19, 2018, as a compensation for the server instability following the release of patch V3.5.
