When we returned to the moon, something woke up.
Something ancient.
Something that followed us back.
2016. A Jeongmian moon mission goes awry when a rockslide is triggered in a lunar cave. When the explorers came back to Tiandi, something followed...
The first attack was four months later on Akitsukuni. A gargantuan beast emerged from the Arctic Ocean, destroyed the Imperial Navy and was only stopped by a nuclear missile. Five months later, the second attack occurred, leaving half of the Gungju continent destroyed but providing humanity with valuable information about these mysterious creatures, their origins and their weaknesses. They were coming from the moon in eggs disguised as meteors, feasted on the electricity of our major cities and were more than capable of besting any conventional army in existence. But the most important news was that they were killable by hitting them in the right places.
The fifth attack arrived a year later. This time, humanity was ready. After the second attack, the Council of Nations assembled a global joint task force to monitor every egg that entered the atmosphere and to combat these creatures for the protection of humankind. Furthermore, the Tactical Surface Fighter, a new Akitsukunese invention that soon spread across the developed world, revolutionised combat against giant creatures by providing a manoeuvrable large-sized vehicle capable of striking the creatures' weak points and avoiding their attacks. For the first time, humanity could claim a true victory. But there is no time to celebrate.
As more eggs begin enter the atmosphere, sometimes simultaneously, the war against these lunar beings is picking up. At the same time, international tensions due to the overpowering nature of Tactical Surface Fighters threaten the united front humanity wishes to present against this threat.
The question still remains: What are these creatures and why were they on the moon...?
My friends, it has finally descended upon us.
