Halo Reach, released in 2010 by Bungie for the Xbox 360, featured a multiplayer announcer who called out medals earned during matches, and Perfection was one of its most prized awards for an outstanding, death-free performance. Clips of the callout circulated in Halo montages, killstreak compilations and reaction videos, where players used it to mark a rare clean game. It remains popular because Halo fans recognise the voice immediately, and because a single word carries the weight of a whole flawless match without needing any explanation.
