On Christmas Eve, a plane carrying chemical weapons crashed near a small town. Part of the city's inhabitants died and rose up in the form of the living dead. Now they roam the city streets, break into houses and hunt living people. In the game Monster Christmas Terror, as part of a squad of soldiers, you will penetrate the city and destroy the zombies. Your character with a weapon in his hands will move along the streets of the city. Look around carefully. As soon as you spot a zombie, aim your weapon at him and open fire to kill. Try to shoot accurately in the head to kill zombies with one shot.
