Following a short delay to complete the *Outlaw Keycard* Community Quest, Story Quests have returned in *Fortnite* Chapter 6, Season 2—this time with a serious challenge, especially for Stage 4. If you're wondering how to equip the Sensor Backpack and scan Mysterious Energy Signatures in *Fortnite*, we’ve got you covered.

How To Find the Sensor Backpack in Fortnite

Stage 3 of the *Wanted: Midas* Questline requires players to open an Outlaw Chest, which can only be done after reaching Rare rarity with the Outlaw Keycard. This step may take several hours of gameplay, involving tasks like robbing vaults, defeating guards, and spending large amounts of gold. Once you successfully open the chest, you’ll unlock Stage 4—one that definitely brings a bit of difficulty to the table.

In this stage, *Fortnite* sends you on a hunt for the elusive *Sensor Backpack*. Unlike regular items, it’s not found inside Chests or scattered across the map. Instead, you’ll find it resting behind the wolf statue located just south of Crime City. This is the same spot where players can join the Secret Wolf Pack, so if you've completed that easter egg, you should already recognize the area. Upon arrival, you’ll see a case sitting on the ground—interact with it, and the Sensor Backpack will automatically equip to your character in place of your Back Bling.

How To Scan Mysterious Energy Signatures in Fortnite Chapter 6

Once the Sensor Backpack is equipped, you’re ready to begin scanning for Mysterious Energy Signatures. There are three total locations to visit, all relatively close to where you picked up the backpack. Simply head up the mountain and keep an eye out for floating exclamation marks above certain spots. As you approach each one, glowing strings of light will appear—just interact with them to complete the scan.

You won’t have to travel far between each signature, but you must scan all three to finish the quest and earn the full XP reward. Be cautious, though—many other players will likely be in the same area working on their own quests, so expect some unexpected PvP encounters. It's a good idea to gather weapons and healing items before heading up the mountain to ensure you’re prepared for any combat situations.

Once the Sensor Backpack mission is complete, you can move on to Stage 5, which involves stealing a copy of the *Mask-Making Book* from the Mask Maker’s Hideout. With proper planning and access to a vehicle, you should be able to finish this next task quickly within the same match.

That’s everything you need to know to equip the Sensor Backpack and scan the Mysterious Energy Signatures in *Fortnite* Chapter 6, Season 2. Stay sharp, stay prepared, and happy hunting!

Fortnite is available on multiple platforms, including PC, consoles, and the Meta Quest 2 and 3 VR headsets.
