The line comes from Bungie's Destiny, first released in 2014, where Commander Zavala briefs Guardians before the strike against Valus Ta'aurc and the Cabal on Mars. The speech was originally a straightforward in-game mission introduction, but players began isolating the opening phrase because its dramatic, resigned tone worked perfectly outside the game. It spread through gaming videos, edits, and meme compilations, often used to frame any unwanted conflict, and remains popular because it instantly signals a serious mission is about to begin.
