Place it just before a reveal or scare, then follow it with a FNAF jumpscare scream for the payoff, and use an enemy spotted cue earlier to set up the threat before the call goes out.
About this sound
This 2.3-second clip is a short animal call, a sharp shepherd's call meant to summon livestock, delivered in a raw, urgent tone. It feels tense and unsettling, like a warning shouted across an empty field at night. It is listed as the third animal-calling audio from Scary Game 2, linked to the mad shepherd.
