Sorana appears to be the Fortnite secret skin for Chapter 2 Season 1. The skin isn't yet available for players to use, but the method for unlocking it is already widely known. Here's how to make sure the Sorana skin joins your collection once it goes live.
Fortnite Sorana: How to Unlock the Secret Skin
The Sorana skin is the first of a new kind of cosmetics Epic Games plans to release to further incentivize completing the Battle Pass challenges. Unlike the skin rewards in previous Fortnite seasons, this skin can be unlocked without maxing out the Battle Pass.
Instead, players must collect all the hidden letters. There's one hidden around the Fortnite island for each letter in "Fortnite," but finding them requires completing certain challenges to unlock the corresponding loading screen. Once the loading screen is unlocked, the hidden letter will appear at the location depicted in the loading screen.
If you've collected all these hidden letters, you should find the Sorana skin in your collection when it goes live.
