What are the NLD?

The main subject is a first-person view of a player holding a weapon in a video game, with a countdown timer in the center of the screen decreasing from 00:25 to 00:08, while a small inset video in the top right shows a person reacting. The scene is set on a cobblestone street in a European-style city, with the player's view remaining mostly stationary as the timer counts down.
