Zombies has been one of Call of Duty's most beloved side modes since its surprise debut, and its audio identity - eerie stings, undead growls and ominous cues - is a huge part of why it sticks in players' heads. Short clips like this one circulate widely on soundboards and meme pages, where creators grab them for gaming edits, reaction videos and horror-themed shorts. It sits naturally beside other horror gaming staples like the FNAF jumpscare scream, and works just as well in shooter montages that already use enemy spotted style callouts.
