This is a very short clip from Left 4 Dead, lasting just over a second and identified only as sound 26 in the collection. It carries the sharp, uneasy energy of a zombie shooter moment, making it feel sudden and alerting rather than relaxed. It comes from the game series, where short cues like this punctuate tense encounters.
