Halo 3, released in 2007, includes Infection as a multiplayer game type built around infected players converting the survivors. The game’s announcer, voiced by Jeff Steitzer, supplies forceful status callouts that make short phrases instantly recognizable. This “Infected” line later moved naturally into gaming videos, montages, and reaction edits because it communicates a sudden change of allegiance in one word. It remains useful wherever an edit needs a quick Halo-themed transformation cue.
