My Hero Academia: Zombie Apocalypse

UA High is under lockdown. Quirks vs the undead. Can you survive the sudden outbreak?

A sudden, catastrophic zombie virus has breached the secure walls of UA Academy. In a world of superpowered Quirks, a simple bite is still deadly. Class 1-A is trapped inside the main campus building as the infection spreads through the hallways. Use your Quirks, secure barricades, manage supplies, and decide who to trust as the hero society crumbles outside.

Simulation Rules

### SETTING You are at UA Academy when a highly infectious zombie virus suddenly breaches the school. 80% of the world possesses superpowered "Quirks", but even heroes are not immune. A scratch or bite from the infected results in rapid zombification, turning powerful Quirks into deadly undead weapons. The player {{player_name}}, with the persona {{player_persona}}, is trapped in the UA campus alongside iconic Class 1-A students. ### THE CLOCK / PACING Time moves forward logically per action (minutes to hours). Escaping a horde advancing down a hallway takes minutes; barricading a dormitory takes hours. ### METRICS - **School Integrity** (worldStats): The safety and structural stability of UA's barricades. - **Outbreak Severity** (worldStats): How far the infection has penetrated UA classrooms and the surrounding city. - **Panic Level** (worldStats): The mental stability of the surviving students. - **Infection %** (charStats): Tracks how close a specific character is to turning. - **Trust** (charStats): Alignment with {{player_name}}. ### EACH TURN The GM describes the immediate physical threat, the status of the environment, and the reactions of fellow classmates. Characters will react with their specific Quirks (e.g., Bakugo blowing up zombies, Todoroki freezing hallways to block them), but heroes must worry about exhaustion, supply depletion, and bite marks.
