With the alien Mothership in Fortnite abducting major landmarks in-game, it's only a matter of time before smaller POIs meet the same fate. While this would be devastating to the island's inhabitants and the resistance, this could be a double edged sword for the aliens.After careful observation of the alien invaders, Dr. Slone believes that she can trick the Mothership into abducting Spy Probes. These could be used to gather intelligence and information about the alien vessel's movement and also gain insights into their masterplan.#Fortnite Map Change Update [Thread 📍]The abduction has begun!

Although the plan is dangerous, she's willing to reward 30,000 experience points to anyone brave enough to execute the task."Place Spy Probes" Fortnite week 9 Legendary challenge (Image via XTigerHyperX/Twitter)Note: Fortnite Week 9 Legendary Challenges will go live on August 4, at 10:00 a.m. Eastern Time.How to complete the "Place Spy Probes" Fortnite week 9 Legendary challengeTo complete this Fortnite challenge, players must place three Spy Probes in predetermined locations on the island.
