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.

The treasure map is the week's challenge likely to take the longest--that is, if you do it the hard way and actually find the treasure map, then follow it. The alternative way is to just follow our guide: Since you don't technically need to get the map to complete the challenge, you can skip going to Shifty Shafts and locating the map and instead head to the location it's ultimately pointing you toward. In this case, it's in mountains just north Salty Springs and South of Dusty Divot. Once there, you'll spot a little collection of stone pillars where you'll also see the Battle Star. We've put images of the treasure map and the precise location of the Battle Star in the gallery below; you can also watch the video above to see us do it.
