Season 5 of Fortnite: Battle Royale is fully underway on PS4, Xbox One, PC, Nintendo Switch, and iOS. As before, the new season brings with it an assortment of new challenges to complete, as well as a variety of Battle Pass rewards to unlock. This time, however, Epic has made a few notable changes to the way certain Battle Pass challenges operate. Here's everything you need to know about the new Season 5 challenges and details on all of the ones available so far.

Once again, players who purchase the Season 5 Battle Pass will get a set of objectives to complete every week, which in turn will go toward leveling the Battle Pass up and unlocking new rewards. Unlike past seasons, however, weekly challenges are now divided into two categories, Free (which are available to all Fortnite players) and Battle Pass (which are reserved for those who've purchased the Pass). That means that even if you haven't bought the Battle Pass, you'll still be able to complete certain objectives and earn rewards.
