After a brief pause to wrap up the Outlaw Keycard Community Quest, Story Quests are back in action in *Fortnite* Chapter 6, Season 2. Brace yourself, though—Stage 4 is no walk in the park. Here's your guide to equipping the Sensor Backpack and scanning Mysterious Energy Signatures in *Fortnite*.
Stage 3 of the Wanted: Midas Quests requires you to crack open an Outlaw Chest, which you can only do after reaching Rare rarity with the Outlaw Keycard. This might take a few hours of your time, involving robbing vaults, taking down guards, and spending a fortune in gold. Once you've got that chest open, Stage 4 awaits, and trust me, it's a challenge.
In *Fortnite*, your quest is to locate the "Sensor Backpack," which isn't tucked away in Chests or lying around randomly. You'll find it on the ground, right behind the wolf statue south of Crime City. This spot is also where you can join the Secret Wolf Pack, so if you've been there before, you're already one step ahead. When you reach the location, you'll see a case on the ground. Interact with it, and voila, the Sensor Backpack will snap onto your back, replacing your Back Bling.
With your new Sensor Backpack equipped, it's time to hunt down the Mysterious Energy Signatures in *Fortnite*. You'll need to find 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. When you reach the nearest one, glowing strings of light will appear. All you need to do is interact with them.
The 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, though, as other players might be on the same mission and won't hesitate to send you back to the lobby. It's wise to gear up before heading to the mountain to be ready 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 could knock out this task in the same game, 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 to play on various platforms, including the Meta Quest 2 and 3.*
