After a brief pause to wrap up the Outlaw Keycard Community Quest, *Fortnite* Chapter 6, Season 2 has reintroduced Story Quests with a vengeance, and Stage 4 is no exception. Here’s your guide to equipping the Sensor Backpack and scanning 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 by reaching Rare rarity with the Outlaw Keycard. This task might take a couple of hours, involving vault robberies, guard eliminations, and a hefty expenditure of gold. Once you've successfully opened that chest, Stage 4 awaits, and it’s a challenging mission.

In *Fortnite*, your quest is to find the "Sensor Backpack," which won't be found in Chests or lying around on the ground. Instead, it's conveniently placed behind the wolf statue south of Crime City, the same location where you can join the Secret Wolf Pack. Many players might already know this spot. When you get there, you'll see a case on the ground. Interact with it, and the Sensor Backpack will replace your Back Bling.

How To Scan Mysterious Energy Signatures in Fortnite Chapter 6

Equipped with the Sensor Backpack, you're now ready to track down the Mysterious Energy Signatures in *Fortnite*. You'll find three of them nearby, just head up the mountain where you'll see three areas marked with exclamation points. When you reach the nearest one, glowing strings of lights will appear; simply interact with them.

These signatures are close to each other, but you must interact with all three to complete the Sensor Backpack Quest and earn your XP. Stay alert, as other players will also be completing their Outlaw Quests and might not hesitate to send you back to the lobby. It’s wise to gear up before heading to the mountain to be prepared for any encounters.

Once you’ve completed the Sensor Backpack challenge, you can move on to Stage 5, which involves stealing a copy of the Mask-Making Book from the Mask Maker’s Hideout. If you manage your time well, you can tackle this in the same game, especially if you have access to a vehicle.

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

*Fortnite is available to play on various platforms, including the Meta Quest 2 and 3.*
