Put it at the peak of a fail or jumpscare sequence, after an Enemy Spotted warning builds the tension and just before the screen cuts to black. Follow it with a FNAF Jumpscare Scream for a second hit, or leave it as the final beat when the defeat alone should close the clip.
Über diesen Sound
This is a short, raw scream lasting just over three seconds, with a strained, high-pitched voice that cuts through suddenly and then stops. It feels tense and startling, like a sudden shock in the middle of a quiet moment, and it carries a panicked energy that makes a failure or surprise feel much bigger than it is.
