This call comes from Half-Life 2, Valve's acclaimed first-person shooter released in 2004, where zombies stalk the streets of City 17 and the abandoned town of Ravenholm. Their groans and calls became part of the game's tense sound design, signalling danger long before an enemy appeared on screen. As clips from the game circulated on YouTube, TikTok and soundboard sites, the sound moved beyond gaming and into horror edits, memes and Halloween videos. It remains popular because it is instantly recognisable to players and immediately creates a sense of dread, even in a clip only a few seconds long.
About this sound
The Half-Life 2 zombie call sound effect, a raspy groan from Valve's shooter. Creators use it for horror edits, game clips and spooky Halloween videos.
This is the distant, guttural call of a zombie from Half-Life 2, ripped from the game's tense, abandoned streets. It opens with a low, rattling moan that rises into a strained, breathy shriek, layered with wet, rasping vocal textures that feel both human and horribly wrong. The sound is short but unsettling, carrying the hollow echo of something shambling just out of sight. It instantly puts a listener on edge, suggesting danger, decay and a threat that is getting closer, which is why it works so well as a sudden scare or a warning that trouble is near.
