Place this clip at the entry point of a scene, after a danger alarm sound effect meme cue builds the warning, then follow it immediately with a fnaf jumpscare scream once the figure is inside the room.
Über diesen Sound
This is a short sound effect of glass shattering as a zombie forces its way through a window, built around sharp cracks and falling shards over about three seconds. It feels tense and startling, like a safe room suddenly is not safe anymore, which makes the break-in register instantly even without anything on screen.
