Treasure chests have been a core part of Fortnite Battle Royale since the game launched in 2017, giving players weapons, items and healing supplies when opened. The opening sound became familiar to millions of players through regular gameplay, then spread further as creators reused it in montages, memes and short-form videos to signal a lucky find. Because the chime is instantly recognisable even without the visuals, it still works as shorthand for reward, surprise and good luck in gaming edits today.
