Massive data storms are happening around the world. The "Operation Delta" game server is overloaded, and the game data collides violently with the reality of the earth. After the storm, "erosion zones" appeared in many places around the world - in-game maps, buildings, supplies and even Hafk soldiers began to randomly appear in reality. This is not a one-time event. The erosion zone is slowly expanding, and advanced units in the game will arrive in batches with the "tidal cycle". Humanity is facing a gradual existential crisis.
