The ‘destroy objects and structures while on a Grind Rail’ challenge in Fortnite can be pretty tricky to complete. The reason it can be hard to complete is that Grind Rails are only really found at two locations on the map. Pair this with the fact that you’ll need to destroy 25 objects, and it’s a challenge that could take you a while.
This challenge is a part of Week 4 in Fortnite Chapter 4 Season 1, and will reward you with 12K XP upon completion. Thankfully, there is a way you can speed it up, by targeting a specific location found in Mega City. Before you go after this, be aware that Mega City can get pretty busy upon landing, so it’s best to grab a gun, move quickly, and then leave once you’ve completed the challenge.
Without further ado, here’s the fastest way to destroy objects and structures while on a Grind Rail in Fortnite.
