After a brief delay to complete the Outlaw Keycard Community Quest, Story Quests have made a thrilling return in *Fortnite* Chapter 6, Season 2. But buckle up, because Stage 4 is no walk in the park. Let's dive into 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 challenges you to open an Outlaw Chest, which requires you to reach Rare rarity with the Outlaw Keycard. This task could take a few hours as you'll need to rob vaults, take down guards, and spend a hefty amount of gold. Once you've conquered this challenge, Stage 4 awaits, and it's a tough one.

In *Fortnite*, your next mission is to find the "Sensor Backpack," which isn't your typical loot from Chests or lying around. You'll find it sitting on the ground behind the wolf statue south of Crime City, the same spot where you can join the Secret Wolf Pack. If you're familiar with the area, you're one step ahead. Upon reaching the location, 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 equipped, your next adventure is to scan the Mysterious Energy Signatures in *Fortnite*. There are three signatures to find, and they're conveniently located near where you picked up the backpack. Head up the mountain, and you'll see three areas marked with exclamation points. As you approach the nearest one, glowing strings of lights will appear, ready for you to interact with them.

The 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 will be tackling their Outlaw Quests simultaneously 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 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.

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