Season 6 of Fortnite has begun, which means players across 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--Season 6's equivalent of Road Trip challenges.

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.
