Fortnite Chapter 6, Season 2's Story Quests are back after a brief pause for the Outlaw Keycard Community Quest, but Stage 4 presents a significant challenge. This guide explains how to equip the Sensor Backpack and scan Mysterious Energy Signatures.
Finding the Sensor Backpack in Fortnite
Stage 3 of the Wanted: Midas Quests requires opening an Outlaw Chest, which necessitates reaching Rare rarity with the Outlaw Keycard. This can be time-consuming, involving numerous vault robberies, guard eliminations, and gold expenditure. Once the chest is accessible, the challenging Stage 4 begins.
The Sensor Backpack isn't found in chests or on the ground. Instead, it's located behind the wolf statue south of Crime City, near the Secret Wolf Pack location. Interact with the case on the ground to equip the backpack.

With the Sensor Backpack equipped, locate three Mysterious Energy Signatures near the backpack's location. These are marked by exclamation points atop a mountain. Interact with the glowing lights at each location.
While relatively close together, interacting with all three is necessary to complete the quest and earn XP. Given the potential for player conflict, it's advisable to gather ample loot before heading to the mountain.
Upon completing the Sensor Backpack challenge, proceed to Stage 5, which involves stealing the Mask-Making Book from the Mask Maker's Hideout. With efficient time management and potentially a vehicle, this stage should be manageable within the same game session.
