After a brief pause to wrap up the Outlaw Keycard Community Quest, the Story Quests are back in *Fortnite* Chapter 6, Season 2, and they're ramping up the challenge. Stage 4, in particular, is a tough one, but don't worry—we've got you covered on how to equip the Sensor Backpack and scan Mysterious Energy Signatures in *Fortnite*.

How To Find the Sensor Backpack in Fortnite

Stage 3 of the Wanted: Midas Quests requires you to open an Outlaw Chest, which means you'll need to get your Outlaw Keycard to Rare rarity. This might take a few hours as you'll be busy robbing vaults, taking down guards, and spending a fortune in gold. But once you've cracked that chest open, Stage 4 awaits, and it's no walk in the park.

*Fortnite* sends you on a quest to find the "Sensor Backpack," an item you won't stumble upon in Chests or lying around. Instead, it's waiting for you on the ground behind the wolf statue south of Crime City—the same spot where you can join the Secret Wolf Pack. If you know the area, getting there should be a breeze. When you reach the spot, you'll see a case on the ground that you can interact with. Go ahead and do so, and the Sensor Backpack will take the place of your Back Bling.

How To Scan Mysterious Energy Signatures in Fortnite Chapter 6

With the Sensor Backpack securely on your back, you're ready to hunt down the Mysterious Energy Signatures in *Fortnite*. There are three of them, conveniently located near where you picked up the backpack. Just head up the mountain, and you'll spot three areas marked with exclamation points. When you get to the nearest one, glowing strings of light will appear. All you need to do is interact with them.

These signatures are close to each other, but you'll need to interact with all three to complete the Sensor Backpack Quest and earn your XP. Stay alert, though, as other players might be completing their Outlaw Quests and could send you back to the lobby. It's a good idea to gear up before climbing the mountain to be ready for any surprises.

Once you've completed the Sensor Backpack challenge, you can move on to Stage 5, where you'll need to steal a copy of the Mask-Making Book from the Mask Maker's Hideout. If you manage your time well, you can tackle this challenge in the same game, especially if you have a vehicle at your disposal.

And that's the complete guide on how to equip the Sensor Backpack and scan Mysterious Energy Signatures in *Fortnite* Chapter 6.
