After a brief pause to wrap up the Outlaw Keycard Community Quest, Story Quests are back in action in *Fortnite* Chapter 6, Season 2. But brace yourself—Stage 4 is no walk in the park. Here's your guide to equipping the Sensor Backpack and scanning those Mysterious Energy Signatures in *Fortnite*.
How To Find the Sensor Backpack in Fortnite
Stage 3 of the Wanted: Midas Quests requires you to crack open an Outlaw Chest, which you'll only get to if your Outlaw Keycard hits Rare rarity. This might take a couple of hours as you'll be busy robbing vaults, taking down guards, and spending heaps of gold. Once you've got that chest open, Stage 4 awaits, and it's a challenging one.
To get the "Sensor Backpack," you won't find it in Chests or lying around. It's actually waiting right behind the wolf statue south of Crime City—the very spot where you can join the Secret Wolf Pack. If you've been there before, you'll know the area. When you get there, you'll see a case on the ground. Interact with it, and voila! 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, you're ready to hunt for the Mysterious Energy Signatures in *Fortnite*. There are three of them, and they're not too far from where you picked up the backpack. Just head up the mountain; you'll see three spots marked with exclamation points. Approach the nearest one, and you'll see glowing strings of lights appear. Interact with them to scan the signature.
These signatures are close to each other, but you need to interact with all three to complete the Sensor Backpack Quest and earn your XP. Stay alert, though—other players might be working on their Outlaw Quests and could send you back to the lobby. It's wise to gear up before you hit the mountain to handle any surprises.
Once you've completed the Sensor Backpack challenge, you can move on to Stage 5, where you'll need to swipe a copy of the Mask-Making Book from the Mask Maker's Hideout. With smart planning, you could tackle this in the same match, especially if you have a vehicle at your disposal.
And that's how you equip the Sensor Backpack and scan Mysterious Energy Signatures in *Fortnite* Chapter 6.
*Fortnite* is available on a variety of platforms, including the Meta Quest 2 and 3.
