Here are the locations where you’ll find the hidden F, O, R, T letters for Fortnite Chapter 2 in the mission loading screens.
Before Fortnite Season 10, Epic released seven weekly challenges every Thursday. When they were unlocked, players could see and complete all seven challenges. Season 10 bought some major changes to the challenge system with missions replacing challenges. Epic have continued with missions in Fortnite Chapter 2, Season 1.
When missions are unlocked, players can only view the first three challenges. In order to view the other challenges, you need to complete objectives. There’s a total of eleven challenges to complete for each mission.
