Fortnite: Battle Royale's season 5, week 7 challenges are here -- after Epic Games mysteriously delayed their rollout, pushing its weekly patch to Thursday and the new challenges to Friday. 

Completing challenges unlocks tiers in your Battle Pass, giving you rewards like emotes, sprays, dances and in-game items. This week, many of the challenges will be familiar to long-time Fortnite players, but as is the case every week, some surprises remain.
