Get ready for Fortnite's Remix: The Prelude event! Scheduled for 6:30PM ET / 3:30PM PT, this musical in-game event promises to be a showstopper. If you're playing the game, jump into a Battle Royale or Zero Build match and head to Restored Reels ahead of the start time. Alternatively, tune in with streamers on Twitch or YouTube. The "Remix" title hints at Epic bringing back elements from Chapter 2 seasons, so it's going to be an exciting event! 🎵
