Adapting Halloween III: Season of the Witch into a mini-campaign for Night Shift: Veterans of the Supernatural Wars (driven by the O.G.R.E.S. engine) bridges classic 1980s horror with urban fantasy and supernatural investigation.
In Night Shift, characters—whether they are Driven investigators, Witches, Survivors, or Supernaturals—are already tuned into the hidden darkness of the world.
Campaign Overview: "Happy, Happy Halloween"
Setting: Santa Mira, Northern California (or a small suburban town tucked away in your campaign’s Night World setting).
Tone: Paranoia, folk horror mixed with sci-fi technology, cosmic dread, and corporate conspiracy.
Grit Level: Cinematic/High-Grit. Firearms are lethal to humans, but Silver Shamrock's synthetic "Andro-Gunsels" and ancient magic make every encounter tense.
Key Factions & Stat Blocks
1. Conal Cochran & The Silver Shamrock Corporation
The Villain: Conal Cochran, a master of dark Celtic sorcery disguised as a jovial toy magnate.
Goal: A mass sacrifice on Halloween night via the Silver Shamrock Halloween Masks powered by stolen pieces of Stonehenge (specifically micro-chips containing pagan runes and mystical megalith fragments).
Night Shift Mechanics:
Cochran counts as a high-level Warlock / Sorcerer NPC. He uses high-level ritual magic and psychic manipulation.
2. The Android Enforcers ("Gunsels")
Description: Lifelike, suited men with mechanical interiors and yellow fluid instead of blood.
Night Shift Stats (O.G.R.E.S. Adaptation):
DV (Defense Value): 14 (low DV makes them harder to hit).
Hit Dice / Vitality: 4d8 (approx. 20–25 Vitality).
Attacks: Unarmed Strike (1d6+2 damage, crushing grip) or Concealed Firearm.
Special Qualities: Immune to mind-affecting spells/psychic abilities, fire damage bypasses their artificial flesh, suffer 1d6 damage max from standard firearm shots unless hit with armor-piercing or super-science gear.
3. The Masks (The Silver Shamrock Curse)
The Trap: Novelty masks (Pumpkin, Witch, Skull) fitted with microchips linked to the Stonehenge monolith fragment.
Activation: Triggered by the Silver Shamrock TV commercial (a hypnotic audio-visual signal).
Effect: Anyone wearing a mask during the commercial suffers rapid disintegration and a fatal swarm of venomous snakes and insects bursts from the head.
Saving Throw: Check vs. Death/Magic at -4 (or a hard d20 check). Success means ripping the mask off in time, incurring partial psychic damage.
3-Act Campaign Structure
Act I: The Hospital & The Mysterious Key
The Hook: A frantic local business owner or shopkeeper is brought to the hospital or emergency room clutching a Silver Shamrock pumpkin mask, babbling about "they're going to kill us all."
Inciting Incident: Before the crew can fully interview him, an Android Gunsel walks into the room, crushes the victim's head, walks out to a car in the parking lot, pours gasoline over himself, and sets himself on fire.
Investigation: The PCs examine the burnt remains. Standard medical checks reveal wire components, micro-hydraulics, and strange yellow fluids. A Perception Check or Rule of 2 Check reveals a car key or order invoice tied to Santa Mira, CA.
Act II: The Town of Santa Mira
The Atmosphere: The PCs arrive in Santa Mira—a company town under a 6:00 PM curfew, monitored by security cameras and patrolling "guards."
Investigation Locations:
The Motel: Owned by Mr. Kupfer or a local who reveals everyone in town works for Silver Shamrock.
The Local Shopkeeper (Ellie Grimbridge equivalent): A party ally searching for a missing family member who tracked shipments back to the factory.
The Factory: Heavy security perimeter guarded by Androids.
Night Shift Mechanics: PCs with Arcane Powers, Psychic Abilities, or Super-Science Tracker gear start detecting a massive surge of ley-line energy surrounding the factory.
Act III: The Factory & The Final Countdown
Infiltration: The PCs infiltrate the Silver Shamrock complex (via stealth, fake IDs, or a assault).
The Big Reveal: Inside, they discover:
A stolen megalith from Stonehenge housed in a high-tech chamber.
Assembly lines where microchips containing crushed stone particles are glued into the masks.
Rooms of android clones (including a decoy clone of an ally or PC!).
Climax:
It's October 31st, 8:50 PM. The broadcast is scheduled to air at 9:00 PM across all major television networks.
The PCs must fight off Cochran's Androids and disrupt the broadcast, destroy the Stonehenge monolith transmitter, or overload the factory's power grid.
Integrating Night Shift Player Classes
| Class | Role in the Campaign |
| Survivor / Driven | Excellent for playing the grounded doctor, detective, or investigative journalist pulling at threads. |
| Witch / Sorcerer | Can sense the corrupted Celtic blood magic radiating from Cochran and the Stonehenge shard. |
| Super Scientist | Can analyze the synth-android fluid, hack the Silver Shamrock transmitter, or disable the microchips. |
| Chosen One / Veteran | Takes the fight directly to Cochran's android enforcers in physical combat. |
Game Master Tips
Tension over Direct Combat: Early on, play up the creepy "wrongness" of Santa Mira. Use the town curfew and constant surveillance to make players feel isolated.
The Countdown Clock: Use a real-time or round-based countdown timer for the final act to simulate the approaching 9:00 PM broadcast.
The Ending Choice: Leave the resolution open-ended, just like the movie—even if the main transmitter is destroyed, can they stop every local TV affiliate in time?
Here is a custom d100 Magic & Weird Science Items Table tailored specifically for a Halloween III: Season of the Witch mini-campaign using the Night Shift: Veterans of the Supernatural Wars system.

| 41–43 | Silver Birch Divining Rod | Points toward the nearest source of high-voltage electricity or active megalithic ley-line energy within 5 miles. |
| 44–46 | Curse-Eater’s Horn | Blowing this horn breaks any active minor hex or illusion within 30 feet, but alerts every Gunsel in the zone to your location. |
| 47–50 | Cailleach's Winter Pebble | When thrown, freezes a door, vehicle ignition, or lock solid for 10 minutes (requires a Strength check of 16+ to force open). |

Here are the stat blocks for Conal Cochran and his key assets, using the O.G.R.E.S. engine mechanics for Night Shift: Veterans of the Supernatural Wars, along with strategies and scaling adjustments for running this mini-campaign with higher-level characters.
Conal Cochran & Santa Mira Stat Blocks
Conal Cochran (Master Warlock / Celtic Sorcerer)
Conal Cochran appears as a charming, white-haired, soft-spoken corporate executive. In reality, he is an ancient practitioner of Celtic blood magic who has fused ancient sacrifices with modern consumer technology.

Advice for Scaling to Higher-Level Characters
If your Night Shift party consists of high-level Veterans, Witches, Sorcerers, or Super Scientists, standard Androids and basic timing pressures will not stop them. Use these scaling adjustments to maintain high stakes and dread:
1. Upgrade the Threat & Action Economy
Increase Cochran’s Hit Dice & Spells: Scale Cochran to 12d8–14d8 Vit. Give him legendary/boss actions, allowing him to cast a minor hex or trigger a facility system at the end of a player's turn.
Heavy-Duty Enforcers ("Type-II Androids"): Introduce heavy-industrial Androids built for security. Give them 7d8 Vit, DV 9, and sub-dermal armor plating that subtracts 3 points from all physical damage taken.
Give Cochran a Coven or Acolytes: Pair Cochran with high-ranking Celtic cultists or corrupted warlocks who act as secondary spellcasters during the final confrontation, forcing the party to divide their focus.
2. Turn the Facility into a Super-Science Lethal Dungeon
High-level parties can slice through low-level guards, so turn the Silver Shamrock Factory itself into a deadly encounter:
Automated Defense Systems: Deploy laser security grids, tear gas, anti-magic dampening fields in storage areas, and automated turret systems (DV 10, 4d8 Vit).
The Monolith Ley-Line Surge: The megalith fragment emits passive arcane radiation. High-level spellcasters who channel magic in the main chamber must make a Saving Throw vs. Magic or suffer an overload backfire (taking 2d6 damage and disrupting the spell).
3. Escalating Time & Broadcast Mechanics
Higher-level characters have access to teleportation, flight, hacking, or high-level gear, which might let them reach Cochran very quickly. Compensate by creating multi-layered objectives:
The Three-Network Problem: Cochran isn't broadcasting on just one station. To stop the Halloween TV commercial, the PCs must disable three regional relay towers around Northern California simultaneously or destroy the core transmitter inside the factory before 9:00 PM.
The Mask Outbreak: Have the broadcast air early in isolated test zones. The PCs have to fight off swarms of venomous vermin and possessed citizens while tracking down Cochran's master feed.
4. Psychological & Clone Warfare
Multiple Copies: When the PCs enter the assembly floor, send out multiple Android clones of their friends, family members, or former party members. Force the players to use perception, super-science scans, or tricky questions to identify who is human before taking a shot.
Here are tailored Random & Triggered Encounter Tables designed specifically for Santa Mira, California, maintaining the eerie corporate-dystopian paranoia of Halloween III and formatted for Night Shift: Veterans of the Supernatural Wars.
How to Use These Tables
Daytime Encounters (d8): Roll once every 4 hours of game time spent exploring the town.
Nighttime Encounters (d10): Roll once every 2 hours after the 6:00 PM curfew.
Factory Grounds / Industrial Zone (d6): Use when trespassing near or inside the Silver Shamrock complex.
Daytime Encounters in Santa Mira (d8)
| d8 | Encounter Title | Narrative & O.G.R.E.S. Engine Mechanics |
| 1 | The Watchful Townsfolk | 2–4 locals silently stare at the PCs from storefronts or porches. If approached, they act cheerful but offer robotic, rehearsed responses praising Silver Shamrock. Skill Check: Insight / Perception reveals they glance nervously at overhead security cameras before answering questions. |
| 2 | The Irish Folk Singer | An eccentric street musician sits on a bench playing a fiddle. He sings an old Gaelic lament about Samhain and the "Stone of the Sun." If a Witch or Sorcerer PC listens, they recognize the song contains embedded spell-craft hints regarding how to disrupt megalithic energy. |
| 3 | Mask Delivery Truck | A red-and-yellow Silver Shamrock delivery van drives slowly past. 2 Android Gunsels are in the front seat. If the PCs follow or inspect it, the truck stops at a local store; the drivers do not speak, breathe, or blink while unloading crates of Halloween masks. |
| 4 | Panicked Tourist / Distraught Family | A mother or father grabs a PC in an alleyway, whispering frantically that their child took off their mask and "something was wrong with their skin." Before they can explain further, a black sedan rolls up and 2 Gunsels politely "escort" the citizen away. |
| 5 | Overhead Loudspeaker Broadcast | The town’s PA system crackles to life with a chime, playing the infamous "8 days 'til Halloween, Silver Shamrock!" jingle. Every local in sight stops dead in their tracks, turns toward the speaker, and quietly hums along until it ends. |
| 6 | Curiosity Shop Secret | An elderly shopkeeper sells vintage antiques. In a back room, he hides an old Celtic woodcut depicting a megalithic sacrifice that matches the modern Silver Shamrock logo. He will trade this info only if the PCs help him bypass the town's phone monitoring system. |
| 7 | Street Surveillance Patrol | A pair of security guards on foot patrol approach the PCs, asking to see their motel keycards or visitor passes. Challenge: Pass a Charisma / Deception check or be escorted directly to the town border (or taken to the factory for "interrogation"). |
| 8 | Mysterious Static Interference | Electronic devices carried by the party (radios, walkie-talkies, scanners) erupt with high-frequency static and a faint heartbeat rhythm. A Super Scientist or Hacker can trace the signal directly to the factory's underground levels. |
Nighttime Encounters (Post-6:00 PM Curfew) (d10)
| d10 | Encounter Title | Narrative & O.G.R.E.S. Engine Mechanics |
| 1 | Curfew Patrol (Black Sedans) | A black Lincoln Town Car sweeps the street with its high beams. Contains 3 Android Gunsels equipped with silenced sidearms. They attack any curfew breakers on sight without warning. |
| 2 | The Test Subject (Rogue Mask) | A teenager wearing a prototype Silver Shamrock Witch mask wanders the street in a trance. If the mask is pulled off, it reveals green, decaying skin beneath. The mask activates if a TV is nearby, triggering a micro-swarm of 1d6 venomous snakes (1d4 damage + Save vs. Poison). |
| 3 | Decoy Android Trap | An android duplicate of a local shopkeeper or missing investigator sits on a park bench weeping. When a PC steps in to help, the Decoy drops its facade and attempts a Crushing Grapple (1d6+2 damage) while signaling patrol cars. |
| 4 | Celtic Blood Rite | In a darkened alley, 3 hooded cultists (Cochran’s human acolytes) are conducting a blood sacrifice over a micro-chip rune to empower the town's local warding grid. Encounter: 3 Cultists (2d8 Vit each, armed with sacrificial daggers and minor hex spells). |
| 5 | The Burning Car Incident | The PCs spot a vehicle parked near the motel engulfed in flames. An Android Gunsel stands inside the fire, calmly burning itself to ash along with incriminating files to prevent a leak. |
| 6 | Static Entity / Arcane Leak | Ley-line energy leaking from the factory manifests as a flickering, electrical ghost on a street corner television in a shop window. It speaks in reversed audio, warning of the "Big Giveaway." |
| 7 | Snipers on the Roofs | A Gunsel equipped with a high-powered rifle (2d6 damage, long range) shoots from a rooftop at any PC attempting to sneak through alleyways. |
| 8 | Desperate Local Resistance | A small group of 2–3 local mechanics armed with shotguns (2d6 damage) are hiding in a garage, plotting to blow up the local relay tower. They are paranoid and mistake the PCs for Cochran’s androids unless convinced otherwise. |
| 9 | The Hypnotic Broadcast | A neon store sign or outdoor monitor suddenly flickers to life playing the Silver Shamrock commercial. Any character looking directly at it must make a Save vs. Mind-Control / Magic or be stunned for 1 round. |
| 10 | Cochran's Projection | An astral illusion of Conal Cochran appears before the party. He politely advises them to leave Santa Mira on the next bus before "the giveaway," offering them cash or safe passage if they turn back immediately. |
Factory Grounds & Underground Encounters (d6)
| d6 | Encounter Title | Narrative & O.G.R.E.S. Engine Mechanics |
| 1 | Laser Security Grid | A corridor fitted with invisible infrared sensors. Bypassing requires a Disable Device / Science Check or taking 3d6 laser/fire damage upon crossing. |
| 2 | Mask Staging Room | Thousands of Pumpkin, Witch, and Skull masks hang on racks. 1d4 of them are "live" and burst into swarms of stinging insects if disturbed. |
| 3 | Android Storage Racks | A room lined with dozens of inactive, unskinned android bodies in glass tanks. A power trip causes 1d6 of them to power on in a violent, twitching state (3d8 Vit each). |
| 4 | Stonehenge Assembly Line | A robotic arm is actively grinding down a piece of the Stonehenge monolith into microscopic dust, filling tiny green microchips. The room is heavy with raw magical radiation (+10% to all Arcane spell checks cast inside, but failure causes a wild magic surge). |
| 5 | Cochran's Elite Enforcer | A custom-built, heavy-duty Android with reinforced titanium framing (6d8 Vit, DV 10, subtracts 3 from all physical damage). It wields a high-voltage cattle prod (2d8 electrical damage). |
| 6 | The Control Room TV Array | A wall of dozens of CRT monitors broadcasting test patterns. Hacking the console allows a Super Scientist to alter the broadcast frequency or shut down curfew locks across the entire town. |
