Capture the Flag is a long-running multiplayer mode in the Halo series, in which two teams try to steal the opposing flag and return it to their own base while defending theirs. The short announcement became familiar to players through countless online matches and Halo gameplay videos, where it marks a sudden shift in momentum. As clips of those moments spread on video platforms and soundboards, the sound took on a second life outside the game, used to signal a steal, a win or a bold move in edits far removed from Halo itself.
