Fortnite has kicked off Season 3 of its Battle Royale mode on PC, PS4, Xbox One, with a bunch of new rewards to boot. That also means a new set of Weekly Challenges to complete, and we've compiled them all below.

Keep in mind you do need a Battle Pass to access the weekly challenges, but they don't necessarily need to be completed before the weekly reset. As long as you finish them within the season, they'll count. The reset occurs every Thursday at 1 AM PT / 4 AM ET.
