Here are all of the week 5 challenges/objectives you need to complete for the Fortnite Battle Royale The Lowdown Mission.
Every week on Thursdays, a new Mission is unlocked for players to complete. There are a total of eleven objectives for each Mission, with one of them being to find the hidden letter in the Loading Screen.
The Loading Screens for this season are awarded to players who have completed eight of the objectives for each Mission and once you have the Loading Screen in your locker, you will be able to see the hidden letter. Finding all of the letters of FORTNITE for this season will unlock the Mystery Skin, so make sure you find all of letters before Chapter 2: Season 1 ends.
