Team Fortress 2 is Valve's class-based multiplayer shooter, released in 2007, and its bold, cartoonish presentation helped it stay popular long after launch. Short musical stings from its menus and intros became instantly recognisable to players, and creators began lifting them for YouTube intros, Twitch streams and short-form edits. The jingle works outside the game because it carries that same confident, comedic team spirit in only a few seconds. It remains a shorthand for jumping into a match, a class reveal or a chaotic team moment, especially among long-time fans of the series.
