Fortnite's challenges for Week 3 of Season 6 are now available, which means it's time to get back on the grind and get those precious Battle Stars. As a refresher, completing these challenges reward you with Battle Stars which, in turn, level up your Battle Pass and allow you to unlock the sweet, sweet cosmetics for your character. Challenges are available in two sets, with one for all players to do and another just for those that have paid for a Battle Pass.

In the free to everyone section, this week's challenges involve reviving a player in five different matches, getting one Damage Trap elimination, and starting the multi-stage challenge by searching a chest in Lonely Lodge. That's all self-explanatory, though the Damage Trap elimination may take some perseverance.
