At just over 15 seconds, the repeating alarm gives you room to cover a full fail or escalating game moment. Download the MP3 once and keep it available for offline playback. Trim a shorter section if you need a compact notification tone, or use the full file as a ringtone. Its loud, persistent pattern can mask dialogue, so lower it when voices matter. For a harder ending, follow the final warning pulse with a FNAF jumpscare scream or an Inception horn.
