Weekly Challenges from the Battle Pass are additional objectives that were introduced in Season 3 and continued in Season 4 and Season 5 of Fortnite Battle Royale. Each week a new set of challenges are unlocked and help you earn XP to level up your tiers.
This page lists all the challenges for Season 3, Season 4, and Season 5 along with tips on completing each one. Starting with Season 5, the first three challenges are available for everyone to unlock, while the last four are only for Battle Pass players. You still need to complete at least four challenges to unlock the weekly reward.
