The game of wargame aims to promote traditional Chinese culture and the heroic stories of Chinese national heroes. This work mainly simulates the scene of Qi's army fighting against Japanese pirates on the coast of Dengzhou. Players can experience the heroic posture and hardships of General Mingwei in the process of controlling the arms and defeating the enemy flexibly. The game uses 2D top-down angle ink style pictures, takes Qi Jiguang's history of anti-Japanese war as the prototype of the game, and integrates various strategic mechanisms such as arms restraint, array bonus, battlefield strategy, offensive blocking and so on. Players need to flexibly control the soldiers' position, improve the overall combat effectiveness by maintaining the array position and cooperating with each other, and block the Japanese pirate offensive with a unique "knife-breaking" mechanism, forming counterattack opportunities to cause a large amount of damage. If the player cannot maintain the formation, he will be subject to the enemy's fire collection and damage bonus, which is easy to defeat. Only step by step can players defeat the Japanese pirates with the "mandarin duck array" method and win.
