This sound comes from Call of Duty: Warzone, Activision's free-to-play battle royale game released in 2020. In the game, the victory theme plays when a player or squad survives to the end of a match, making it instantly recognisable to millions of Call of Duty players. Clips of wins, montages and streamer highlights spread the sound beyond the game itself, and editors began reusing it as shorthand for any hard-earned success. It remains popular because it carries the excitement of a battle royale win even outside Warzone.
