In Fortnite Chapter 3, new seasonal challenges will appear every two weeks. They grant great amounts of XP, in addition to being relatively easy to complete.
Here, you will have to land at the Daily Bugle, then finish your game in the top 25.
Where is Daily Bugle located?
The Daily Bugle is a huge building filled with disused offices. It's visible from afar -- you'll see the name of the building in huge lettering on the outside.
To complete this challenge, you just have to land on the large building, then go on to finish in the top 25.
If you're confident in your abilities, you can try to win the game by eliminating your enemies. However, it's also prudent play safe and just keep hidden as much as possible.
Completing this challenge will net you a bonus of 25,000 XP, which is a pretty sizeable jackpot for a mission this simple.
