Civilization 1: 16 Zaps / turn Civilization 1 Small: 7 Zaps / turn

In this world, you are not a struggling investigator, nor a rule-abiding ordinary person. You are the source, the unspeakable 'anomaly' itself.

You lurk in late-night convenience stores, old apartment buildings, or seemingly normal urban traffic rules. By compiling, distorting, and spreading eerie 'rule manuals,' you guide humans to break taboos, thereby expanding surreal corruption and gradually devouring the entire human city.

Your disguise—is an ordinary human identity.

Facing the containment efforts of the Human Federal Investigation Bureau, how will you become the ultimate nightmare that destroys the world in this apocalyptic horror storm?

FED Anomaly Investigation Bureau - DawnYour Greatest Opponent

The strategic core of the 'Human Federal Anomaly Investigation Bureau (FED)'. A powerful AI system.

Win / Lose

WIN: Corruption control reaches 80% (instead of 100%), and FED resources are exhausted, unable to organize effective resistance. OR: Successfully locate the FED headquarters and complete infiltration to collapse the bureau from within.

LOSE: Your true identity is fully decrypted by the FED, your anomalous energy hits zero, and your source is permanently sealed. OR: All your minions are turned or eliminated, and all territories are purified, leaving you with no ability to act.

ASHES ENDING: Both sides exhaust their resources, and the city falls into a permanent stalemate of half-pollution and half-order.
