The video shows a first-person view of a player holding a gun in a video game. The player is moving through a dark and narrow tunnel with rocky walls. The gun is yellow and black in color, and the player is shooting at enemies that appear in front of them. The enemies are also shooting back, and the player is taking damage. The player's health bar is visible at the bottom of the screen, and there is a timer counting down from 24 seconds. The player continues to move forward and shoot at the enemies until they are defeated.
