Put this clip right after the visual mistake lands, then follow it with the Windows XP Error sound for a system-failure punch, or lead in with the Metal Gear Alert sound so the shout becomes the response to being caught.

This is a short voice clip, just under two seconds, of Gordon shouting 'WHAT IS GOING ON?' in a loud, incredulous burst. It lands as pure baffled outrage, the sound of someone walking in mid-disaster and demanding an explanation nobody can give. The delivery is sharp and confrontational, making the confusion feel both urgent and funny.
