Writing About Zombies

Introduction

Zombies have shambled through human storytelling for centuries, evolving from Haitian spiritual beliefs into one of horror's most enduring and versatile monsters. For writers, the zombie offers something unique: a blank canvas that can represent consumerism, conformity, pandemic fears, or simply pure survival terror.

This guide synthesizes historical research, game design mechanics, and narrative craft into practical tools you can use immediately. Whether you're writing interactive fiction, a novel, or a screenplay, you'll find the foundations you need to build authentic, engaging zombie worlds.

The History of Zombies

Understanding where zombies come from enriches your writing and opens creative possibilities beyond the standard Hollywood shambler. The zombie has a complex, often troubling history rooted in slavery, colonialism, and spiritual belief.

Haitian Vodou: Where It All Began

The original "zonbi" wasn't a flesh-eating monster—it was something far more terrifying to those who believed in it. In Haitian Vodou, a zonbi is a person whose soul has been captured by a sorcerer called a bokor, rendering them a will-less slave. The fear wasn't of zombies; it was of becoming one.

The most famous alleged zombie case is Clairvius Narcisse, who was declared dead in Haiti in 1962 and buried the next day. In 1980, he returned to his village, claiming he'd been exhumed, drugged, and forced to work on a sugar plantation. His brother allegedly arranged his zombification as punishment for a family land dispute.

African Folklore Roots

The word "zombie" itself traces back to Central and West African languages, brought to Haiti through the transatlantic slave trade. Understanding these linguistic roots reveals how deeply African spirituality shaped Haitian Vodou.

In Kongo cosmology, Nzambi a Mpungu was the supreme creator deity—distant but all-powerful. When enslaved Africans were forced to adopt Catholicism in Haiti, they merged their traditional beliefs with Catholic saints in a process called syncretism. The Christian God became associated with Nzambi, while lesser spirits (lwa) took the forms of Catholic saints.

The creation of Vodou itself was an act of cultural resistance. When slave masters banned African religious practices, enslaved people developed a hybrid system that appeared Catholic on the surface while preserving African spiritual frameworks. The zombie—a person stripped of will and autonomy—became a powerful metaphor for slavery itself.

Ancient Roots Across Cultures

The idea of the dead returning isn't unique to Haiti. The Epic of Gilgamesh (c. 2700 BCE) contains the oldest recorded threat of the dead rising to eat the living. When Gilgamesh rejects the goddess Ishtar, she threatens to "bring up the dead to consume the living" and "make the dead outnumber the living."

The Colonial Transformation

The zombie we know today was shaped by the American military occupation of Haiti (1915-1934). Returning soldiers and journalists brought back "exotic stories" that painted Haiti as a land of devil worship and living dead—narratives that helped justify the occupation to American audiences.

William Seabrook's 1929 book The Magic Island was the first popular English-language text to describe zombies as reanimated corpses. Though only 12 pages addressed zombies directly, those pages defined them as "a soulless human corpse, still dead, but taken from the grave and endowed by sorcery with a mechanical semblance of life." This directly inspired the 1932 film White Zombie.

The Science of Zombie Powder

The Clairvius Narcisse case caught the attention of Harvard-trained ethnobotanist Wade Davis, who traveled to Haiti in the early 1980s to investigate whether there was a pharmacological explanation for zombification. His findings, published in The Serpent and the Rainbow (1985), proposed a scientific mechanism behind the folklore.

The tetrodotoxin theory was elegant: in low doses, this neurotoxin blocks sodium channels in nerve cells, causing paralysis while leaving the victim conscious but unable to move or speak. In Haiti's hot climate, burial occurs within 24 hours of death—theoretically allowing time for a poisoned person to be buried alive, then recovered before actual death occurred.

Davis defended his work by pointing out that folk medicine formulas are inherently variable—not every batch would have the same potency, and bokors would refine their techniques through trial and error over generations. He also emphasized that zombification was primarily a cultural phenomenon, not purely pharmacological. The psychological impact of the ritual, combined with the victim's belief in Vodou and the bokor's power, might be as important as any drug in creating compliant behavior.

The Evolution of Zombie Media

While Romero's Night of the Living Dead is justifiably credited with creating the modern zombie, the path from Haitian folklore to flesh-eating hordes was paved by decades of pulp literature, horror comics, and genre-defining films.

Early Literature: The Weird Fiction Era

Before zombies shambled across cinema screens, they lurched through the pages of pulp magazines. H.P. Lovecraft's serialized story "Herbert West—Reanimator" (1922) appeared in Home Brew magazine as a science fiction horror parody of Frankenstein. While not traditional zombies, Lovecraft's reanimated corpses established the template of death conquered by science gone wrong.

Richard Matheson's I Am Legend (1954) deserves special attention. Though technically about "vampires," it established virtually every convention of modern zombie fiction: a scientific/disease origin, worldwide pandemic, last survivor narrative, and the complete collapse of civilization. The infected in I Am Legend behave far more like modern zombies than traditional vampires—mindless, plague-spreading, and overwhelming in numbers.

The Comics Code Kills the Undead

During the early 1950s, EC Comics published some of the most inventive horror stories in American history through titles like Tales from the Crypt, Vault of Horror, and Haunt of Fear. These comics regularly featured zombies, often with darkly ironic twist endings.

Beyond Romero: The Post-1968 Zombie Renaissance

While George Romero created the template with his "Dead" films, other filmmakers expanded and subverted zombie conventions in surprising ways:

Zombie Taxonomy

Zombies are more than just shambling corpses. Understanding how to categorize them by origin, behavior, and physical state helps you craft consistent rules for your fictional world and create unique variations that serve your story's themes.

By Origin/Cause

The source of zombification profoundly shapes your story's tone, rules, and whether a cure is possible. Each origin brings different narrative possibilities.

By Behavior

How zombies act determines your story's pace and the types of challenges survivors face. Behavior categories often matter more to gameplay/survival than origin.

By Physical State

The body's condition affects what your zombies can do and how horrifying they appear. Physical state also determines how long your outbreak can last.

The Science of Zombies

The best zombie fiction grounds its horror in plausible science. Understanding real parasites, diseases, and epidemiology helps you create infections that feel terrifyingly possible.

Real-World "Zombie" Parasites

Nature has already created zombie-making organisms. The fungus Ophiocordyceps unilateralis infects ants, hijacking their behavior to spread its spores. But here's the fascinating detail that makes it even creepier: Penn State research revealed the fungus doesn't invade the ant's brain at all. Instead, fungal cells form a three-dimensional network surrounding muscle fibers throughout the body, controlling it "like a puppeteer pulls strings."

Epidemiology for Writers

The R₀ (basic reproduction number) tells you how contagious a disease is—how many people one infected person typically infects. Understanding this helps you write realistic outbreak scenarios.

Rabies and Prion Diseases: Real-World Inspiration

Some of the most terrifying zombie characteristics come directly from real diseases that already exist. These aren't just inspiration—they're proof that nature can be more horrifying than fiction.

When the CDC Used Zombies

On May 16, 2011, the Centers for Disease Control and Prevention did something unprecedented: they used zombies to teach Americans about emergency preparedness. Dr. Ali S. Khan, director of the CDC's Office of Public Health Preparedness and Response, published a blog post titled "Preparedness 101: Zombie Apocalypse." It would become one of the most successful public health campaigns in history.

The genius was in the approach. Khan recognized that disaster preparedness messages were boring—people ignored them. But zombies? People loved zombies. The post walked readers through what supplies to gather (water, food, medications, tools, sanitation items) and what plans to make (evacuation routes, emergency contacts, emergency meeting location) using a zombie apocalypse as the hook.

The Results Were Staggering:

• The campaign cost approximately $87 (for the stock zombie photo) plus staff time
• Normal CDC blog posts received about 3,000 hits over several weeks
• The zombie post got 30,000 hits the first evening—and crashed the CDC's servers
• In October 2011, the CDC released a graphic novel, "Preparedness 101: Zombie Pandemic," which received 517,600+ views
• The campaign generated international media coverage and made preparedness cool

The CDC's zombie campaign proved that fiction—even absurd fiction—can serve real-world purposes. By meeting people where their interests already were (zombie media was experiencing a massive boom in 2011), the CDC delivered genuinely useful information that might save lives during real emergencies.

For writers, this demonstrates the cultural power of zombie fiction. Your stories aren't just entertainment—they're part of a larger conversation about survival, society, and how we respond to crisis. The line between fiction and practical preparation is thinner than you might think.

Zombie Media Deep Dive

The best way to learn zombie writing is to study the masters across every medium. Each format—books, comics, games—has unique strengths that can inform your interactive fiction. Books excel at internal character work, comics pioneer visual horror language, and games innovate mechanics that can translate to choice-based storytelling.

Essential Books

These novels demonstrate the range of what zombie fiction can achieve, from military procedurals to literary fiction to scientific horror.

• Max Brooks - The Zombie Survival Guide (2003) and World War Z (2006)
  Brooks revolutionized zombie fiction with a mock survival manual followed by an oral history of a global zombie war. World War Z was directly inspired by Studs Terkel's oral histories, structuring the narrative as post-war interviews. The fragmented perspective allows Brooks to examine zombie apocalypse from military, political, economic, and personal angles. Writing lesson: Multiple viewpoints can create a fuller picture than any single protagonist could provide.
• Brian Keene - The Rising (2003)
  Winner of the Bram Stoker Award, Keene's zombies are possessed by demons rather than driven by virus or radiation. They retain intelligence, memories, and can use weapons and drive cars. This creates a fundamentally different threat dynamic. Writing lesson: Intelligent zombies open tactical storytelling—they can set traps, coordinate attacks, and learn from failures.
• Mira Grant - Feed (Newsflesh Series, 2010)
  Set 26 years after the initial outbreak, Grant's world has adapted to a zombie reality with amplification testing and security protocols. The series follows blog journalists covering a presidential campaign. Hugo Award finalist that demonstrates how society might genuinely adapt. Writing lesson: Post-apocalypse doesn't mean civilization ends—it means civilization changes.
• Colson Whitehead - Zone One (2011)
  Literary zombie fiction that explores trauma and capitalism through the lens of post-apocalyptic Manhattan cleanup crews. Whitehead introduces "stragglers"—zombies frozen in mundane activities like stocking shelves or typing at keyboards, caught between death and purpose. Writing lesson: Zombie behavior can reflect thematic concerns; stragglers embody workers trapped in meaningless labor.
• M.R. Carey - The Girl with All the Gifts (2014)
  Infected children retain intelligence and self-awareness, creating profound ethical questions. The fungal "Ophiocordyceps" basis grounds the horror in science while allowing for unique variations. Writing lesson: Smart infected characters can be protagonists, not just threats, opening entirely new narrative territory.
• Isaac Marion - Warm Bodies (2010)
  Proved zombie romance could work by giving readers a sympathetic zombie POV character who maintains his internal monologue. R's perspective makes the familiar genre fresh while exploring consciousness and connection. Writing lesson: POV choice transforms genre expectations—seeing through undead eyes changes everything.

Comics & Graphic Novels

Comics have pioneered zombie storytelling techniques that translate surprisingly well to text-based fiction, particularly in visual pacing and reveal mechanics.

Video Games

Video games have pioneered zombie mechanics that interactive fiction can adapt. While you can't replicate gameplay, you can translate the design principles behind these systems.

• Left 4 Dead (2008-2009) - AI Director System
  The game's revolutionary AI Director monitors player stress levels, performance, and positioning to dynamically spawn enemies. When players are calm, it escalates. When overwhelmed, it provides breathing room. This created emergent pacing that felt authored but remained unpredictable.
  
  Interactive Fiction Application: Variable pacing based on reader choices. Track "stress" through failed choices or resource depletion. When readers have succeeded recently, introduce harder challenges. After failures, provide easier wins or character moments. The Director also introduced Special Infected—unique zombie types (Tanks, Witches, Hunters) that require specific tactics.
  
  Adaptive Storytelling: Your branching narrative can acknowledge player patterns. If readers consistently choose stealth, introduce an encounter where stealth fails. If they always fight, present a scenario where combat is futile.
• Dead Rising (2006+) - Improvised Weapons & Time Pressure
  Features 140+ improvised weapons from a shopping mall setting, from teddy bears to lawnmowers. The combo weapon crafting system (duct tape + creativity = new tools) rewards experimentation. The original game ran on a strict 72-hour real-time timer—if you didn't complete objectives, survivors died permanently.
  
  Interactive Fiction Application: Resource creativity over resource scarcity. Give readers environmental assets they can combine. "You have duct tape and a baseball bat" becomes meaningful if readers can suggest combinations. The timer creates urgency—time-limited choices or survival countdowns generate similar pressure without real-time mechanics.
  
  Environmental Storytelling: Dead Rising's mall is packed with environmental comedy and tragedy. Your locations should be similarly rich with interactive details that reward exploration choices.
• Dying Light (2015) - Day/Night Cycle with Volatiles
  First-person parkour zombie survival where movement is as important as combat. During the day, zombies are slow and manageable. At night, "Volatiles"—fast, intelligent hunters—emerge, transforming the game into survival horror. This creates natural risk/reward cycles: venture out at night for better supplies but face exponentially greater danger.
  
  Interactive Fiction Application: Time-of-day choices with dramatically different consequences. Scavenging at night yields better resources but higher risk. Day trips are safer but more crowded (other survivors are also out). Players must weigh when to move.
  
  Movement as Mechanic: Dying Light proves traversal can be engaging. In text, this becomes route choice—rooftops vs. streets vs. sewers. Each path has unique hazards and opportunities. Parkour-style decision trees where players navigate obstacle courses through choice.

International Zombie Fiction

Different cultures bring unique perspectives to zombie stories, shaped by their own folklore, fears, and cinematic traditions. While Hollywood dominates the genre, some of the most innovative and fresh zombie narratives have emerged from international filmmakers who reimagine the undead through their cultural lenses.

Structuring Your Story

The biggest challenge in choose-your-own-adventure writing isn't creativity—it's architecture. Seven binary choices create 128 possible paths. Twenty choices create over a million. You need strategies to manage this complexity.

The Branch-and-Bottleneck Method

The most sustainable approach for long-form interactive fiction. Branches diverge for meaningful variation, then converge at "bottleneck" points—events that happen regardless of which path the reader took. This lets you maintain scope while preserving the feeling of meaningful choice.

Natural Convergence Points for Zombie Stories

• Location Arrivals: Everyone eventually reaches the safehouse, hospital, or extraction point—how they arrive and in what condition varies.
• Major Events: The horde reaches the barricade. The helicopter arrives. The power fails. These happen to all readers.
• Time Cycles: Dawn breaks. Night falls. The weekly supply run. Time-based events naturally synchronize branches.
• Character Deaths: Key NPCs may die at different times on different paths, but major deaths can serve as convergence points.

The Gauntlet Structure

Perfect for survival horror. A relatively linear central thread where bad choices lead to death, backtracking, or quick rejoining. The zombie genre naturally supports this—wrong turns get you killed, which organically prunes your story branches.

Other Structural Patterns

Beyond the core branch-and-bottleneck and gauntlet approaches, several other narrative structures offer unique advantages for zombie stories:

• Time Cave: Heavy exponential branching with many distinct endings. While unsustainable for long-form narratives, this works brilliantly for short zombie survival vignettes—every choice matters, every path feels unique, but the scope remains manageable.
• Diamond: Branches diverge dramatically then converge at critical pinch points. In zombie contexts: reaching safehouses, surviving major horde encounters, day/night transitions. Readers experience different journeys but hit the same major story beats.
• Quest: Modular geography-focused clusters where each location (mall, hospital, suburb) is a self-contained mini-story with its own branching. Perfect for open-world zombie survival where readers choose which areas to explore.
• Open Map: Reversible travel between nodes—readers can move freely between discovered locations. Creates a sense of agency but requires careful state tracking to prevent narrative contradictions.
• Loop and Grow: Cycles through similar situations (daily supply runs, nightly defenses) that unlock new options each iteration as skills improve and resources accumulate. Great for base-building zombie survival stories.
• Floating Modules/Storylets: Quality-based narrative where encounters unlock based on character state rather than linear position. A "betrayal" encounter triggers when trust is low, regardless of location. Offers tremendous replayability but requires sophisticated state tracking.

Iconic Zombie Locations

Location shapes everything in zombie fiction—the resources available, the density of threats, the psychological atmosphere, and the thematic resonance. Understanding the narrative DNA of classic zombie settings helps you choose (or subvert) them effectively.

Tracking Variables Instead of Branches

Rather than creating separate paths for every choice, track choices as variables that affect outcomes later. A Chapter 1 decision between "Brutality" and "Compassion" doesn't create two story branches—it sets a stat that determines how NPCs react in Chapter 5.

Designing Meaningful Choices

A choice feels meaningful when the reader has enough information to decide thoughtfully and believes their decision changes something they care about. The best choices involve incomparable options—safety versus morality, logic versus loyalty—where there's no objectively "correct" answer.

The Safe / Risky / Wild Card Triad

A reliable template for structuring choices:

Choice Frequency Guidelines

Offer reader interaction every 100-200 words. Avoid "walls of text" over 400 words without a choice. Even simple choices asking how the reader feels maintain engagement and establish that the story is listening.

Survival Mechanics

The best zombie CYOA makes readers feel the weight of survival. Tracking resources, health, and infection creates tension and forces meaningful trade-offs. Here are systems adapted from games like Project Zomboid and Resident Evil.

Health State Tracking

A simplified three-tier system works well for narrative pacing:

• HEALTHY: No penalties. Full range of options available.
• INJURED: -1 to physical actions. Some strenuous choices unavailable. "Your wounded leg slows you down."
• CRITICAL: -2 to all actions. Death risk on failed checks. Limited options. "Every step is agony. You're not sure how much longer you can keep going."

Infection Progression

Based on Project Zomboid's Knox infection model—a ticking clock that creates mounting dread:

Noise Mechanics

Sound attracts zombies. This simple rule creates organic consequences for player choices and adds a layer of strategy to every encounter.

Characters in Zombie Fiction

Zombies are a force of nature. The actual story is always about the survivors—their relationships, conflicts, and the choices they make when civilization crumbles.

The Player Character

In CYOA, the protagonist is inhabited rather than performed. Define their capabilities and limitations, not their biography. Keep physical descriptions vague enough for reader projection. Focus on actions, reactions, and sensations rather than identity.

Essential NPC Archetypes

Relationship Mechanics

Track how NPCs feel about the protagonist using a simple numerical system:

Pacing Your Horror

Constant tension exhausts readers. Constant safety bores them. Great zombie fiction follows a rhythm—peaks of terror followed by valleys of quiet that make the next peak hit harder.

The Roller Coaster Model

Action scenes are the drop; slow scenes are the climb. Save the largest drop for the climax, with smaller peaks building toward it. As Resident Evil 2's director explained: "Having nothing but tension throughout the whole game would be exhausting for players, so we designed save rooms as a safe place to take a breather."

The Function of Safe Rooms

Safe rooms in survival horror serve multiple purposes beyond just saving progress:

• Emotional release: The hope they represent makes the danger meaningful
• Pacing mechanism: Prevents reader exhaustion
• Strategic hub: Where plans are made and resources managed
• Paradoxical tension: Knowing you're safe makes you dread leaving

Recommended Rhythm Template

1. Introduction/Setup — Establish normalcy (low threat)
2. First Encounter — Initial zombie contact (medium threat)
3. Brief Recovery — Process what happened, establish rules
4. Escalating Encounters — Build tension incrementally
5. Peak Crisis — Major setpiece, highest stakes
6. Resolution/Breather — Aftermath, character moments
7. New Threat Teaser — Plant seeds for next escalation

Craft & Style

Zombie fiction lives in the body. The best writing makes readers feel the cold sweat, the aching muscles, the smell of decay. Here's how to write visceral horror that pulls readers into the nightmare.

Second-Person Immersion

CYOA typically uses second person ("You step into the room..."). This POV is intimate but can become repetitive. Vary your sentence structure to avoid the "You... You... You..." drone:

Sensory Detail That Works

Horror works best through specific, unexpected sensory details. Skip the clichés ("heart pounding," "blood ran cold") and find fresh observations:

• Smell (underused and powerful): The sweetness of decay. Copper on your tongue. Motor oil and old blood. The staleness of air in a room sealed for weeks.
• Sound and Silence: The wet sound of something dragging itself. Silence that buzzes in your ears. Your own breathing, too loud. A distant crash that could be anything.
• Texture: The slickness of blood under your shoes. Cold metal in sweating hands. The give of rotting wood under your weight. Something brushing your ankle in the dark.

"The fear isn't in the monster you see—it's in the one you don't. The banging locker with nothing inside. The closed door at the end of the hallway. Your imagination will always create something worse than you could describe."

Gore Guidelines

Graphic content works best when used strategically:

• Less is more: Reserve detailed gore for moments of maximum impact. Constant splatter numbs readers.
• Escalate gradually: Start with implied violence, build to explicit only at key moments.
• Consequence matters: Violence should affect characters—injuries linger, trauma accumulates.
• Avoid torture porn: Extended suffering without purpose feels exploitative, not scary.

Common Mistakes to Avoid

Even experienced writers fall into these traps. Knowing them in advance helps you write cleaner, more effective zombie fiction.

Go Write Your Zombie Story

You now have everything you need: the history and mythology to give your zombies depth, the science to make them feel real, the mechanical systems to create meaningful survival tension, and the craft techniques to pull readers into your nightmare world.

Remember the core truth of zombie fiction: the undead are never really the point. They're the pressure that reveals who your characters truly are. The shambling horde outside the barricade matters less than the conflicts inside it.

Start with your rules—decide what your zombies are, how they work, and what kills them. Build your structure before you write. Track variables instead of multiplying branches. Give your readers choices that matter, consequences that stick, and moments of hope that make the horror bearable.

Then let the dead rise, and see what your survivors are made of.
