A recent Fortnite leak reveals a different type of Festival mode called Music Battle that could become available in the future. Fortnite Chapter 5 Season 1 has brought a music-based mode, which requires players to nail every note and build a streak using instruments. This rhythm game features an extensive lineup of songs and lets players form a band of four artists. The good news is that Fortnite Festival will remain permanent and receive content updates on a regular basis.
