In the video, we see a first-person view of a person holding a gun and walking through a corridor. The person then aims the gun at a door and fires, causing the door to open. The person then continues walking through the corridor, aiming the gun at various points along the way. The corridor is dimly lit, with blue and green lights illuminating the walls. The person's gun is black with a green light on the side. There are no other people or objects visible in the video.
