Place it near the start of an empty-place edit, after a wide establishing shot and before the punchline footage, then follow it with the Inception Horn Sound Effect for a heavier reveal and use the Enemy Spotted Sound Effect earlier to set up the search through deserted streets.
About this sound
This six-second voice clip has Captain MacMillan speaking in a calm, measured tone about Pripyat, contrasting its former population of 50,000 with its deserted streets and ending on the image of a ghost town. It feels bleak, quiet and unsettling, with a dry edge that makes emptiness feel dramatic rather than simply sad. The line comes from Call of Duty 4: Modern Warfare, during the mission All Ghillied Up.
