game mode
the game has two modes, each mode can set three kinds of difficulty, and all the original game modes are used:
1, plot mode, which can unlock the plot and watch the story in the game. The two sides are fixed and cannot be changed
2. In encounter, players can freely set up both sides and limit weapons, and can freely change the map. Kill all characters except yourself
resource system
players in the game need to proce resources in order to carry out a series of operations. There is only one kind of currency for resources, which follows all the settings of the original version. Players need to use the mining truck to mining or oil wells. Money is the main resource. Money is used to build new buildings, training units or to enable special services
building system
in the game, according to different buildings, it can be divided into the following categories. All the original buildings are used in the game:
1. Base, which can build buildings
Mining equipment, including stopes and oil wells, can make money to buy equipment Barracks, in a broad sense, include airfield, soldier barracks, chariot factory, etc., which can build units Power plant, power plant can rece the cooling time between proction units5. Combat laboratory can unlock more advanced arms, but it will also rece the efficiency of power plant
6. Defense facilities can resist foreign invasion
Super weapons, including nuclear bombs, have great lethality8. Neutral buildings can be protected by garrison. All neutral buildings have their own capacity, and soldiers from both sides are not allowed to enter neutral buildings at the same time
R & D system
in the game, more advanced arms can be unlocked by building all kinds of buildings. Among them, a large number of arms can be built in the combat laboratory, and more than 80 arms can be developed in the game:
< P > 1, soldier, barracks2, engineer, barracks + mining yard
3, police dog, barracks
4, rocket pilot, barracks + air finger Department
5, spy, Barracks + battle lab

6. Nanjing Massacre refers to the large-scale massacre carried out by the Japanese army in Nanjing and its surrounding areas for several months after the Republic of China lost the Nanjing defense war and the capital Nanjing was occupied on December 13, 1937 ring the Anti Japanese War of China from 1937 to 1945. Japanese war crimes include looting, rape, massacre of a large number of civilians and prisoners of war. The scale of the massacre and the number of casualties are not universally recognized in the world, but it is generally believed that the number of deaths exceeds 300000
in China, the Nanjing Massacre is often an important concern of nationalism. In Japan, however, the public's understanding of the Nanjing massacre has a wide range of different emotions and views. In particular, some far right Japanese believe that the Nanjing Massacre is an exaggerated or even fabricated Anti Japanese diplomatic tool. Some also believe that the denial of the Nanjing Massacre is a manifestation of historical revisionism and denial. Because the Japanese have different opinions on the Nanjing Massacre, depending on the views of the speakers, the Nanjing Massacre may be called "Nanjing Massacre", "Nanjing Massacre", and "Nanjing Incident". The understanding of Nanjing Massacre is one of the problems in the diplomatic and people's relations between China and Japan
in western countries such as Europe and the United States, the Nanjing Massacre is generally translated into English as Nanjing massacre or rape of Nanjing, but on the whole, people's understanding of it is often far less than that of the Nazi genocide
few Chinese and Japanese who witnessed and witnessed the Nanjing massacre are still alive, and those who can witness will soon die with the time. However, this unprecedented tragedy in Chinese history is still pending. Let us alive, especially the generation who witnessed this period of history, have the responsibility to thoroughly clarify the Nanjing Massacre, the most outstanding Japanese military crime in the second Sino Japanese War, so as to vindicate our ancestors, set an example for our descendants, and even more for the 340000 compatriots who died in the Nanjing Massacre
date and place: ring the trial in Nanjing (from January 1946 to November 1948), he personally experienced the "Nanjing Massacre" and was once a "member of the International Committee of Nanjing security zone", pastor Meiqi (after returning to the United States, he served as the resident pastor of Yale University), Professor Bates (Professor of history, Jinling University, later vice president of the University), After returning to the United States, he served as professor of New York United Theological College and vice president of Nanjing Red Cross Society. Bedes said: "after the fall of Nanjing, the terror reached its peak in two and a half to three weeks, and the terror was serious from the sixth to the seventh week." In addition, the treasurer and Secretary of the International Committee of Nanjing security zone, Professor of Sociology of Jinling University, Mr. Smith, also told the Nanjing trial court that "in the first six weeks, he protested twice a day." Thus, the Far East International Military Court ruled that "in the first six weeks after the Japanese occupation, the total number of civilians and prisoners slaughtered in and around Nanjing was more than 200000.". Therefore, most scholars and ordinary people follow the "Nanjing Massacre" for only six weeks“ The "Nanjing Massacre" is not just six weeks, although the massacre in these six weeks is the most serious
if we need to specify the most serious stage of the Nanjing Massacre, it should be from the fall of Nanjing on December 13, 1937 to the arrival of the new Japanese garrison commander, naojiro Tanya, on February 5, 1938. Two days later, shigen Matsui, commander in chief of Japan's Shanghai Garrison, ordered the restoration of order in Nanjing. Despite the promises of general Matsui and major general Tiangu, the Japanese massacre, rape, plunder and arson in Nanjing did not improve significantly. At that time, the administrative secretary of the Nazi German Embassy in China, George W; Rosen's telegram from Nanjing to the Ministry of foreign affairs in Berlin on February 10, 1938 also said: "the Japanese terror rule in Nanjing has reached an unprecedented level." In his telegram on March 4, he made a clearer analysis of the Japanese atrocities: "the situation in and around Nanjing has been somewhat stable in February and this month... The number of Japanese atrocities has decreased, but the nature has not changed." Rosen also mentioned that until the day he started writing a letter (March 4), there was no Chinese store in Nanjing. Professor Smith said in his 1938 book "a portrait of the disaster of war in Nanjing" that in March 1938, many gates in Nanjing were still sealed. In addition, Falkenhausen, head of Chiang Kai Shek's German Advisory Group, stayed in Nanjing at that time and worked in the German Embassy. His manuscript records that "a Japanese soldier raped a girl in an American church on March 19.". The terrorist situation of Nanjing in February and March reported by the westerners who stayed in Nanjing is completely in line with the description made by many Chinese who stayed in Beijing. On February 15, 1938, Jin shengpan, the director of the field rescue department, and Jiang gonggu, the section chief, made their first tour of the urban area after the fall of Nanjing in the car of liges, an American overseas Chinese. In his march of the fall of Nanjing, Jiang recorded the following: "out of Xinjiekou, through Taiping Road, Confucius Temple, turn to Zhongshan Road, there are no houses along the way, Except for the enemy soldiers, the pedestrians can never see anyone else. We can't bear to see the desolate scene again. "
commander Guo Qi of the Central Military Academy of Chiang Kai Shek's Guard Corps fled three months after the fall of Nanjing. He wrote a record of blood and tears in the fallen capital, which was serialized in xijingping daily in August 1938. After the war, Guo appeared in court to testify in China's military court for the trial of war criminals and confronted Gu Shoufu, head of the sixth division of the Japanese army, as the crazy executioner of the Nanjing Massacre. Guo wrote: "it's said that the beast soldiers always shoot, rape and kill in the first three days after they come in... As a result, it doesn't stop after a week, and it doesn't stop after three months!" Niu Xianming, another battalion commander of the Corps, graated from the Japanese Sergeant school. At the beginning of the Anti Japanese War, he was studying in the French military academy and immediately returned to serve his country. After being trapped in the enemy's rear, Niu Luofa became a monk. He had lived in Nanjing for eight months before escaping. Now he is still living in Los Angeles, USA. In his book "return to vulgarity", he describes the scene of a masquerade monk escaping from danger by taking the Beijing Shanghai train: "at that time, Beijing and Shanghai had been occupied for more than half a year. In order to ensure their rule, the Japanese military gendarmes were no longer able to kill openly in public places,... Under the surveillance of the devils, I dare not look around too much; So I took back my sight, closed my eyes, and rubbed the Buddha beads on my neck with one hand to chant Buddha Li kechen, a cultural man, fled from Nanjing on June 3, 1938, after more than two months of refuge in the countryside in the west of Nanjing. He wrote the May story of falling into Beijing, which was serialized in Hankou Ta Kung Pao in July 1938. Li described what he saw in Nanjing: "recently, although it is rare for Japanese soldiers to rape women in the daytime, it is still very common at night. When my female compatriots were walking in the street, the Japanese soldiers came forward to stop them. In the name of inspection, they felt all over their bodies, molested and played with them at will. But they had to bear humiliation and listen to their actions. Otherwise, they would raise their bayonets and stab them to death immediately. Therefore, there was no woman in the street ring the day. "
the terror situation in Nanjing lasted until the summer of 1938, although it was obvious that after the middle of March, the extent of massacre and altery graally decreased. It can be said that the period from the middle of March to the end of May is the "small Massacre". The most powerful proof is that two charities (Nanjing Branch of the World Red Cross and Nanjing Branch of the Chinese Red Cross) buried 806 people in May 1938. Lin Na explained the reason in her "a tale of blood and tears in Jinling": "from the time the Japanese soldiers entered the city to the time I left - May 20 - the work of burying the corpses never stopped. In fact, they could not be buried either. One batch of them were buried, and another batch of them were added immediately." Although the self governing Committee of traitors was established in Nanjing as early as January 1, 1938, with Tao Baoqing and sun Shurong as the chairman and vice chairman, it failed to delay the burning, killing, rape and plundering of the Japanese army, so that the "small Massacre" continued until the summer of 1938. The order of Nanjing was not restored until November 1938, when Liang Hong's "reform government" (established in Shanghai in March) was still in Nanjing. Objectively speaking, the time limit of "Nanjing Massacre" should be said to be "half a year", or three months of "massacre" and three months of "small Massacre"“ In the first six weeks after the Japanese occupation, more than 200000 civilians and prisoners were slaughtered in Nanjing and its vicinity, the judgment of the Tokyo Trial said And he said, "people outside the city are a little better than those inside. All the villages within 200 Li (66 miles) around Nanjing are in the same state in general. "“ "200 Li around Nanjing" should be referred to as "Nanjing and its vicinity". It starts from Wulong mountain in the northeast of Nanjing City in the East, on the South Bank of the Yangtze River, passes through yaohuamen, xianhemen, qilinmen, Maqun, cangbomen, gaoqiaomen, shangshangzhen, crosses the Qinhuai River in the East, goes to huashentemple and Jijiawa in the west, crosses the Jiangnan (Beijing Jiangxi) Railway in the west, and goes to Shanghe town opposite Jiangxinzhou in the northeast. In fact, this is the defense line for Nanjing, mainly in the southeast of Nanjing, which is also a densely populated area. At the same time, this area was the battlefield of Nanjing's defense, and most villagers fled before the Japanese army arrived. Most of them were old and weak, women and children. Few of the Japanese who failed to escape were spared
the Japanese army slaughtered the city all the way to Nanjing
the Japanese army forced 200000 troops to Nanjing, slaughtered the city all the way, raped, built houses and ruins, and disappeared. After landing at Jinshanwei in Hangzhou Bay on November 5, the sixth division of the Japanese army went directly north to break Songjiang city. According to Tian Bolie, a famous journalist of the British "Manchester Guardian", reported a telegram sent by a British journalist after his personal visit to Songjiang on January 14, 1938: "the whole city of Songjiang could have accommodated about 100 thousand residents, but I only saw five old Chinese hiding in a house of the French church with tears. They had cut off their food and begged me to take them to Shanghai." Suzhou, known as Venice of China, was captured by the third division of the Japanese army on November 19. According to an article in Shanghai's Miller's review in 1938, "the beautiful and elegant Suzhou city had 350000 residents, but after the Japanese army occupied the city, there were only 500 left." But the most painful thing is as follows: "the Japanese army insulted women from all walks of life. I'm afraid no one can estimate how many women have been raped by Japanese soldiers who are full of animal lust. " In his recent book Chinese women as Japanese army comfort women, Su Zhenqi said: "after the fall of Suzhou City, more than 2000 women were taken captive." In her article "the founding of the people's Republic of China ring the Anti Japanese War and women's issues" published in Chongqing's Central Daily on January 15, 1939, Chiang Kai Shek's wife, Song Meiling, confirmed that the Japanese army not only gave the number of the abcted women for altery, but also "stripped them of their clothes and stabbed them on their shoulders" in public. On the one hand, it shames our female compatriots and prevents them from running away. On the other hand, it serves as a tool for their animal desire. " Wuxi, known as "little Shanghai", is an instrial center with a population of 900000 at ordinary times. Since late October 1937, it has been bombed by Japanese planes almost every day. According to the above-mentioned article in Miller's review, on November 10, the Japanese army dropped more than 160 bombs in one day, causing rubble to the factories and commercial areas of the city and casualties to the military and the people
