One of the last challenges of the Dive! mission in Chapter 2, Season 1 of Fortnite asks you to go in search of the letter "R", with only this week's loading screen as a clue.
This challenge is the same concept as that of the Hidden Stars tasks of Season X. Each week there's a new location to discover.
No need to look too far, it's at the Hydro 16 dam that you'll have to go. This notable place is at the heart of various mission objectives.
Map
Take your best glider and go straight to the middle of the dam. The "E" is prominently located on the lamppost in the centre, on the side of the water reservoir. Building a small staircase will allow you to access it quickly.
We recommend playing in Team Rumble mode to achieve this challenge, as it will prevent you from being attacked by eager players too early in the game.
