Fortnite is streamlining its various battle passes, allowing players to earn XP and progress through multiple passes. The change will affect Lego Fortnite, Music Pass (formerly Festival Pass), and the main battle pass. Players can earn rewards without having to grind levels or purchase them separately. Additionally, new Music and LEGO Passes will offer free and premium rewards. Epic Games promises a unified purchasing option for all passes in the future.
