This guide features exactly where you'll need to go to find Fortnite's hidden "E" letter location in Season 11! You'll want to grab all of these hidden letters to unlock the mystery skin for the season.
These are pretty much exactly like the battle stars from previous seasons, but instead of gaining stars you will now gain experience. This is a pretty big change because you would gain tiers by earning stars and not experience, but for Chapter 2 it looks like you will only need to obtain xp.
You'll need to complete eight of the Dive! Challenges to unlock the loading screen that enables you to search for the letter E.
Hidden E Loading Screen
Once you've completed eight of these challenges, you will receive the Dive! loading screen! It looks like the alter egos are going to battle in this screen, and you get a whole lot of Sludge skins trying to take down our heroes! If you look over the light post on the dam, you'll see the letter we're looking to obtain!
The E location is above the light-post on the Hydro 16 dam!
