We're in the midst of Week 2 of Fortnite: Battle Royale Season 6, which means there are challenges for players to undertake on PS4, Xbox One, Nintendo Switch, PC, and mobile--albeit a batch that isn't especially exciting. As has been the case recently, the new challenges are divided up into two categories: those available to everyone, and those reserved for players who've purchased a Season 6 Battle Pass. Either way, completing them will earn you XP and help you to unlock some of the new Season 6 rewards, not to mention kill some time until the new gun arrives.

The challenge that requires the most legwork this week is to visit all of the Corrupted Areas, which began cropping up around the map after the locations were visited by the mysterious purple cube toward the end of Season 5. There are seven of these Corrupted Areas scattered around the island, and completing the challenge is simply a matter of heading to all of them over the course of several matches. You can see where all of them our in our dedicated Corrupted Areas challenge guide.
