Starting in 2223, a new type of energy device called a "reactor" was developed, and the three major powers that existed in the world began to mass-produce it. Countries started a crazy arms race. In 2233, a war broke out like holmium medicine being ignited. This year was called the first year of the attack. The time was pushed forward to 2240. The seven-year scientific and technological revolution developed the most basic conventional quick-build weapons. Within a year, an oil company named Black Penguin hatched a huge conspiracy: it announced a false oil source, attracting the attention of three major powers. At the same time, it sent spies to steal the oil and apply it to the shuttle it developed, preparing to go to the moon to exploit new resources first. The three countries formed a fortress alliance in times of crisis and defeated the Black Penguin in 2241. Temporarily putting the Black Penguin Crude Oil Company's moon landing plan in vain, young commanders then led one reactor after another and began to re-occupy various regions, once again splitting four large camps under the three major alliances.
CNFT: Fight for justice and glory, a gathering place for fortress elites, never stir up trouble in advance
FYFT: A camp born for flying, good at attacking enemies from the air
WIG: Small elite unit, good at quick battles, coming and going without a trace
OFT: A team that hides its strength, few people have seen their true appearance
After the three major alliances were ordered to disband, all camps began their own activities.
Mission: Fearless adventurous spirit
