Killionaire is one of the medal announcements heard in Halo: Reach, the 2010 shooter developed by Bungie. The callout became familiar through multiplayer clips, Forge videos, and later short-form gaming edits that used Halo medals as instant payoff sounds. Its appeal comes from how clearly it communicates an unusually high streak in just over a second. Even years later, players still use it in montages because the Halo announcer style is instantly recognizable and still fits modern competitive highlight editing.
