Halo Reach, released in 2010 by Bungie, is a first-person shooter set in the Halo universe, and its multiplayer matches use a match announcer to call out key moments as the clock runs down. The ten-second warning is one of those in-game cues, designed to tell players that a round is about to end and that any final push has to happen now. Outside the game, Halo fans and gaming editors have reused the short line as a countdown, because it carries instant recognition for players while still working as a time-pressure cue for viewers who have never played it.
