The Hunter is one of the Special Infected in Left 4 Dead 2, Valve's cooperative zombie shooter released in 2009, and its scream serves as an audio warning that the fast, pouncing enemy is about to attack. Because the sound is instantly recognisable to players of the game, short clips of it spread across gaming soundboards and video edits, where it was reused far beyond its original gameplay purpose. It remains popular as a jumpscare scream because it instantly signals danger and surprise, even for viewers who have never played Left 4 Dead 2.
