Overtime challenges for Fortnite Season 9 have officially been found in the files by data-miners, and they will reward new cosmetic styles for Battle Pass skins, loading screens and XP. The challenges themselves seem pretty easy to achieve, as completing the main challenges unlock multiple rewards.
The easiest challenges include dealing damage to opponents with a variety of weapons via Party Assist and also visiting locations on the map. We will keep you updated with a cheat sheet once the challenges officially release.
The challenges are expected to appear in-game relatively soon after the patch drops, so players should be getting prepared if they want to grab these cosmetic rewards as fast as possible.
