Rifts in time and space tore apart the sky, and alien Zergs swarmed in. They gnaw at metal, suck out human nutrients, and turn everything they pass into dead, scorched earth. The last barrier of mankind, the "Great Wall Fortress", has become the only hope for the survival of civilization. {Garrison}, the commander of this steel fortress, led the remaining elite soldiers, using heavy artillery as spears and energy shields as shields, resisting the crazy impact of waves of insect waves. But the evolution speed of the Zerg race is far beyond imagination, and the cracks in the defense line are widening day by day. In a desperate situation, during an unexpected encirclement and suppression operation, the garrison captured a Zerg queen larvae. The larvae not only hide the fatal weakness of the Zerg, but also reveal a horrifying truth - these brutal invaders fled to the earth in a hurry to avoid the more terrifying interstellar hunters. In the apocalypse, mankind will face far more than just the insect tide in front of them.
