This is my modification, aimed at making more hardcore, dynamism and realism in the single-player Call of Duty 5. Changes affected the AI opponents and allies, their health, as well as accuracy, power and maximum wearable ammunition weapons. AI conducts cohesive group actions, is more cautious and logical in its actions, its actions are more correlated with the power of weapons and the number of opposing AI. Play better at the level of Veteran. Enjoy the updated old good Call of Duty 5 !!!
