In the video, a person is playing a video game. The game is set in a dark, dungeon-like environment with stone walls and archways. The player is holding a gun and is moving through the environment, looking for enemies to shoot. As the player moves, the gun's crosshairs are centered on the screen, and the player's health and ammo count are visible on the screen. The player successfully shoots an enemy, and a red circular graphic appears on the screen, indicating the enemy has been hit. The player then continues to move through the environment, looking for more enemies to shoot.
