To complete the Fortnite Season 10 Ultimate Effort challenges, you will need to collect recordings left by the Visitor in different locations. The next ones will be in Moisty Palms and Greasy Grove, on top of a building and in a Tacos restaurant respectively.
For this challenge, you will have to go to the top of the tallest building in Moisty Palms, a hotel. The recording is at the top, on a ledge. In Greasy Grove, you'll need to go to a Tacos restaurant, go to the back, and find the recording lying on a table.
As a reminder, it's easier to complete this challenge in Team Rumble, since with the respawn, you won't have to worry about dying.
Remember that Fortnite Season X (10) lasts until Monday, October 14, when the next season should arrive. If you want to reach tier 100 of the Battle Pass and thus unlock all the unique rewards of this season, you will therefore need to complete a large part of the weekly challenges offered, and we are helping you to achieve them.
