Call of Duty Zombies is a game mode from the Call of Duty series that became especially popular through online gameplay videos, montages and reaction edits. Short audio clips from Zombies are widely reused because they instantly suggest pressure, horror and arcade-style survival. Even when a specific cue is clipped out of context, players still associate the sound with frantic rounds, revives and being cornered. That strong recognition keeps Zombies audio popular in memes, gaming compilations and short-form videos years after people first heard it in matches.
