Season 6 of Fortnite is live, which means players across all platforms--PS4, Xbox One, PC, Nintendo Switch, and mobile--have a slew of new cosmetics and other items to earn in Epic's popular battle royale game. Just as in previous seasons, Epic is rolling out a set of challenges every week throughout Season 6. Finishing these will help level up your Battle Pass, which in turn will unlock rewards. If you manage to clear all of the challenges in a given week, you'll also complete a Hunting Party challenge--this season's equivalent of the Road Trip challenges from Season 5.

Just as before, the reward for completing a Hunting Party challenge is a special loading screen, which features a subtle hint pointing to the location of a free Battle Star hidden somewhere around the island. If you complete one week's set of Season 6 challenges, you'll earn the loading screen below, which shows off a group of characters gathered in a farm.
