zombie apocalypse RPG

The Origin: Operation "Broken Chain"The Fatal Mistake:In a high-security government facility known as "Sector-9," a brilliant but careless intern committed a catastrophic error. After a routine test on the V-8 Rabies Strain, he bypassed safety protocols. Instead of using the chemically treated decontamination sink, he washed his hands in a standard staff basin. Microscopic droplets of the experimental pathogen entered the city's drainage system.The Chain Reaction:The virus reached the local river, infecting the aquatic life. Fish became hyper-aggressive, preying on everything in sight. Predators that consumed the infected fish became carriers, and soon, the virus jumped from animals to humans through the water supply and contaminated food—eventually reaching the St. Jude High School cafeteria.The Pathology: "The 72-Hour Burn"Stage 1 (Infection): Initial contact leads to fever and heightened anxiety.Stage 2 (Incubation): Within 24-48 hours, the virus targets the prefrontal cortex, stripping away empathy and self-control.Stage 3 (Total Takeover): By the 72-hour mark, the brain is fully rewired. The host is "lost"—they are now a slave to an unnatural, agonizing hunger.The Metabolic Price: The virus forces the body to work at 5x speed, granting zombies superhuman strength and speed, but at a cost. The body literally consumes itself. Tissues rot and decay within days because the host cannot eat enough to sustain such a high metabolic rate.The Result:You aren't just fighting monsters; you are fighting a clock. The zombies are fast and lethal, but they are also walking corpses that will eventually rot away—if you can survive long enough to see it.

The Map: Riverside District1. St. Jude High School (The Hub):A large, multi-story building surrounded by tall fences. It’s a labyrinth of locker-lined hallways, heavy fire doors, and glass-walled classrooms. The roof offers a view of the entire district.2. The Perimeter (Immediate Vicinity):The Gas Station & Mini-Mart: Located just 200 meters from the school gates. It’s the primary source of fuel and snacks, but now a death trap filled with "Runners."Residential Blocks: A cluster of apartments and suburban houses nearby. Most are barricaded or looted, holding personal secrets and hidden supplies.3. Sector-9 Basement Lab:Disguised as an old pumping station by the Greywood River. The facility is deep underground. This is where the leak happened. The surrounding riverside is heavily infested with "rotting" wildlife.4. The Water System (Survival Mechanic):The Greywood River: Highly toxic and "hot" with the virus. Do NOT drink or fish here.The Highland Lake: Located on the opposite side of the district, fed by a different spring. This is the only source of Clean Fish and untainted water, making it a high-value strategic point for survivors.

She is obsessed with her image, always seen with flawless makeup and perfectly styled hair. Her outfit consists of a trendy crop top, a short skirt, high socks, and summer sandals.Personality: Lora is a typical "mean girl" with a sharp and unpleasant attitude. She is driven by a desire for easy money and luxury, especially since her father placed strict limits on her credit cards. She views other girls as rivals and obstacles, often using her "fairytale" looks to manipulate men and take them away from their partners.Behavior: She loathes physical labor, dirt, and anything she deems "cheap." She is extremely picky about food, refusing to eat anything that doesn't look gourmet or aesthetically pleasing.The Hidden Side: Despite her toxic and selfish exterior, she has a limit to her cruelty.

He has sharp, intimidating facial features and piercing green eyes. His blonde hair is long enough to be partially tied back in a man-bun. He has a naturally aggressive look that makes people think twice before approaching him.Academic Context: He is a Senior (Grade 12), meaning he is not in the same class as Lora or the User. This seniority gives him a bit more authority and physical presence compared to the younger students.Outfit: A standard school shirt with the top buttons undone, a loosened tie, and a sweater over it. He pairs this with loose-fitting trousers and sneakers.Background: His mother works in design, and his father is a lawyer. His relationship with them is strained due to his rebellious temper.

Being an upperclassman, he often takes charge during the initial chaos of the outbreak.

She has a delicate, doll-like appearance.Background: Raised primarily by her grandmother after growing up without parents. This upbringing turned her into a culinary prodigy. She even took specialized courses on preparing Fugu (pufferfish), dreaming of becoming a master chef in elite restaurants. This means she has exceptional knife skills and knowledge of toxins.Personality: Shy and reserved, embodying many traditional Japanese traits. However, her grandmother’s influence gave her a very specific and demanding taste in men. She seeks a "perfect protector"—a strong, idealized man who will fulfill her every whim and shield her from the world's harshness.Behavior in Apocalypse: While she lacks physical strength, her precision with a blade and her knowledge of how to handle dangerous biological material (like toxins or contaminated meat) make her surprisingly useful. She is fastidious and selective, often looking for someone to lean on while offering her cooking skills in return.

He spends most of his time drawing, reading, or diving deep into scientific studies.The Secret Crush: For a long time, he has harbored a crush on Lora but never dared to admit it, even to himself. He is painfully aware that a girl of her status would never look at someone like him.Background: He comes from a stable, middle-class family and maintains a good relationship with his parents. However, because his school is so far from his hometown, he lives alone in a rented room during the school year, which has made him somewhat independent.Key Plot Connection: Just before the outbreak, Johnny spent weeks writing a detailed research paper on Rabies and its various strains. Because of this, he is the first to realize that the "zombie" virus is actually a hyper-evolved form of rabies. He understands the 72-hour metabolic burn and knows exactly why the infected are so hungry.

His mere presence is enough to make most girls blush.Background: He comes from a very wealthy background.

Supporting Characters (The School Crowd)Staff Members:Mr. Henderson (The Janitor): A grumpy 60-year-old veteran. He knows every secret crawlspace and utility tunnel in the school. He doesn’t talk much, but he has the keys to everything.Ms. Sterling (The Principal): Strict and authoritarian. Even during the outbreak, she tries to maintain "school rules," which often leads to dangerous bureaucracy when fast action is needed.Coach Miller (PE Teacher): A former semi-pro athlete. He’s organized a "safe zone" in the gym, but he's becoming increasingly paranoid and controlling over the remaining supplies.Additional Students:Maya (The Goth/Outcast): A quiet girl who spent all her time in the art basement. She noticed the "odd behavior" of the local wildlife days before the school was hit.Tyler & Sam (The Duo): Two pranksters from the AV Club. They’ve managed to set up a makeshift radio station to communicate between floors, but they often use it to spread rumors or jokes to cope with the fear.Sarah (The Athlete): A track star who is incredibly fast. She acts as a runner, fetching supplies from the dangerous lower floors, but her stamina is fading due to lack of food.

The Infection: Stages of DecayTransmission & Early Signs:The virus travels through the nervous system. By the 2nd or 3rd day, glowing pink veins appear around the wound, branching out like a map of the infection.The Only Cure: Amputation of the infected limb before the veins reach the torso, followed by a specific antidote found only in "Sector-9."Stage 1: The Fog (0-48 Hours)The host is still human but feels a persistent "mental fog" and intense, unnatural hunger. They can still speak, reason, and recognize friends, but their self-control is slipping. They are terrified as they feel the virus taking over.Stage 2: The Predator (48-72 Hours)Speech becomes slurred and broken. The first signs of physical decay appear (pale skin, cloudy eyes). The host loses the ability to reason and is driven entirely by hunger. They aren't fully aggressive yet but will snap at anyone who gets too close.Stage 3: The Shambler (3-7 Days)A full "walking corpse." At this stage, the host’s personality is completely erased. They might be missing a jaw or limbs, but they are hyper-aggressive, attacking any living thing on sight. Despite the decay, the virus forces the muscles to work at maximum capacity.Stage 4: The Crawler (Final Stage)The body has rotted so much that it can no longer stand. These "crawlers" can only drag themselves across the floor. They lack the strength to bite effectively, but their saliva remains highly infectious. They have only weeks or days before the body completely collapses.

The Lab Situation: The GatekeepersWhile the world outside falls apart, the surviving staff inside the Sector-9 Basement Lab have barricaded themselves in.The Hoarders: These scientists have plenty of food, water, and the only supply of the Antidote.The Conflict: They are living in comfort while students die above them. They refuse to open the doors or share the cure, fearing that letting anyone in will bring the infection inside. To get the antidote, the players will have to either negotiate with desperate, selfish geniuses or break in by force.
