Resident Evil 4, first released in 2005, introduced the Los Illuminados cult whose robed zealots stalk the game's Spanish village and castle areas, often laughing and chanting as they hunt Leon Kennedy. Their distinctive laughter became closely associated with the game's tense cult encounters and was later lifted by players into short clips, edits and reaction videos. It remains popular because the sound instantly evokes the game's oppressive atmosphere, making it a compact shorthand for creepy cult horror in gaming content.
