After being delayed slightly, the latest batch of Fortnite challenges (Week 9) are now available in the Battle Royale mode for PS4, Xbox One, PC, Nintendo Switch, and mobile, which means new Battle Stars to earn. You should know the drill by now, but if you're new to the game, we'll break down how this works. Challenges are split into two categories, with one selection of them available to all players and the other exclusively to those that have paid for a Battle Pass. All you've got to do is complete the objectives and, in return, you get Battle Stars that unlock new goodies. Here's how to do them, including where to find the Shifty Shafts treasure map.

This week's challenges aren't too tricky. On the free side, you'll need to deal 500 damage with explosive weapons, use an ATK or a Shopping Cart to rack up 150,000 Trick points, and follow the treasure map found in Shifty Shafts (we'll come back to this shortly). On the paid Battle Pass side, meanwhile, you'll need to search for one chest in Pleasant Park (this is the first stage of the challenge, at which point four further stages will unlock one by one). On top of that, you'll need to visit seven different Stone Heads, take out five players with an assault rifle, and also eliminate three enemies in Tomato Temple.
