Launching the Promethium Wars: Designing a Narrative Kill Team Campaign

Those who have been reading this blog for a while will know that I love the idea of stories emerging from game play. While this is obvious in games like D&D, I’m also interested in trying to create similar emergent experiences with other game systems. I’m a member of a local wargaming club where we play games of Kill Team and 40K on a weekly basis. I think there’s something special about a wargaming campaign that tells a story. Not one written in advance, but one that emerges—slowly, chaotically, gloriously—from the dice rolls, the table banter, and the narrative fragments players build together. With that in mind I volunteered to run a narrative campaign for the group. As a result, Promethium Wars, a narrative Kill Team campaign, was born.

I wanted something simple enough to run with minimal admin, but rich enough to spark real engagement amongst the participants. Something where a quick game on a weeknight could feel like part of a bigger war. Games would no longer be transactional affairs, but rather threads forming a larger narrative. And with twelve players already signed up—divided evenly across the Imperial, Chaos, and Xenos factions—it’s clear the idea has struck a chord.

Design Principles

Narrative and Emergent Storytelling were at the core of the campaign design. I didn’t want to script the campaign’s twists and turns. Instead, each week’s outcomes will steer the story. Players can dive in as much (or as little) as they want—whether that means writing full-blown battle reports, communicating in character or just rolling dice and watching the story evolve.

To keep things light and playable for everyone, I leaned into the principle of Limited Admin. No complicated map-tracking or bookkeeping for the campaign manager (me) or the players. Just clear weekly themes, short prompts, and a shared space for storytelling. Every game counts, but you don’t need to log three hours on a spreadsheet for it to matter. The minimum admin for each participant is to log game results and send them to me. Of course, if the players get really into the game the Discord server should begin to grow with narrative reports and banter, but it is not a requirement.

Each faction has its own win condition, giving players a reason to show up and push their agenda forward. The Chaos and Imperial factions want control of Pyrothis V and must win the most number of games. The Xenos faction, who can fight for either side, wants to grind both enemies down to an ineffective stalemate, wins if the Chaos and Imperial sides are effectively tied (two points difference). Regardless of the game mission being played, there’s always a motive. The stakes are casual but meaningful—exactly the balance I was aiming for.

Structure and Themes

The last principle was Short Campaign Length. I don’t want the campaign to fizzle out. Keeping it short ensures that the high energy at the start can be maintained. Short, sharp, explosive. I hope that this will keep the players coming back for more campaigns in the future.

Therefore, the campaign unfolds over four weeks, with a new theme each week to guide missions and inspire storytelling. These themes won’t constrain players—they’re meant to be narrative fuel. Players are encouraged to run games when and how they like, as long as it fits the week’s vibe. The four themes are:

  • Week 1: Infiltration and Sabotage
  • Week 2: Open Conflict
  • Week 3: Firestorms and Disaster
  • Week 4: Final Gambit

Once reports begin trickling in from the front lines, I’ll be putting together a short newsletter each week to highlight key developments, turning points, and of course, the faction scores.

A Living, Breathing War

Perhaps the most exciting part of any narrative kill team campaign is the player energy. Already, folks are crafting characters, naming squads, and giving them relevant back stories. And while there’s no pressure to write stories, every player is invited to contribute. These tales—written, spoken, or just shared at the table—are what will give the campaign its true shape.

Ultimately, Promethium Wars is a story we’re writing together. And the pen happens to be shaped like a bolter.

Final Thoughts on Narrative Kill Team Campaign Design

The campaign is started mid April and will run to mid May. I’m aiming to learn from this experience to hone the opportunity for emergent narrative play and see what comes out. Depending on the actions of the players I’m considering running a multiplayer finale to cement the end of the campaign. But the fact that this is an emergent experience I guess I’ll have to wait and see how the whole thing pans out.

Once the campaign has finished, I’ll post the results along with any lessons learned from the experience.

New Scenarios for MartyCon 2025

Martycon 2025 starts today! This is a mini weekend long convention of my friends involving lots of game playing and enjoying rural Western Australia. This has been running for three years now and last year was a blast! As with last year I have volunteered to run another multiplayer Space Weirdos game for the crew. My mind is always full of scenario and campaign ideas so instead of one scenario, I’ve dreamed up two. One longer and more involved, while the second is a quicker more brutal affair. I’ve also made sure to tie them narratively into my Mordax Prime setting.

As always these are multiplayer affairs and I try to include a mix of immersion, differing objectives and emergent play. I really want to maximize the engagement of the players, giving them fun and different experiences each time.

Scenario 1: Void Ship Boarding Action

For my main scenario of the weekend I wanted to continue one of the more recent Mordax Prime narratives; the manifestation of a Saint on Helios Magna. Additionally, I wanted to replicate the tight confines of a boarding action in a 40K setting. We pick up the story where the villainous Ferrymen seek to escape the system in their ship, only to be boarded by the pursuing Imperials.

Setting the Scene

With a roar of void engines the Revenant bore away from the world of Helios Magna. The blighted Ferrymen and their cargo were safely on board, and it was time to strike for home. Mad Claw stalked the bridge nervously, the authorities would be on to them soon enough and he needed to escape fast. Raiding in the heart of an Imperial system was decidedly not his style, he preferred isolated settlements or orbitals. But the rewards offered by the Ferrymen were too good to be ignored and worth the risk. So, he had thought at the time.

Klaxons screeched over the vox system, enemy ship closing. But from where? The adversary must have been jamming his sensors. Mad Claw realized that his pursuers had much faster ships than anticipated. Though hardened and battle tested, the Revenant was no speedster. Intrigued, he squinted at the viewing screen pausing as what he saw sank in. Chilling his blackened soul. While not large, the enemy vessel was painted black and red with the stylized I emblazoned on its foredeck. Inquisition. With a roar Mad Claw bellowed commands, sending crew and servitors alike scurrying to position. It would take all his guile and cunning to escape this trap.

Aboard the Strike Ship Purgator’s Blessing Inquisitor Jaegermann watched the pirate vessel draw closer. His teams failure in the Drula Sector of Helios Magna had enraged him. But on reflection, fighting a three-way battle to the objective had been his error. Hurriedly he made amends with the understandably angry Prioress of the Veiled Light.

A team of Lancet marines and Battle Sisters supported by a contingent of Inquisitorial storm troopers stood by as the Purgator’s Blessing closed the distance. They could not let these foul heretics escape with the so-called Saint. Who knew what the Ferrymen had in store for the poor unfortunate. A green globe flashed rapidly on the control slate and Jaegermann smiled grimly. Time to bring these wretches into the Emperors Light.

With a lurch the boarding torpedoes released, speeding towards their prey.

Objective

This will be a team game, fought under time pressure. The Imperials have two objectives:

  • Capture the “Saint” and get them off the enemy vessel within 4 turns
  • Damage the Geller field generator to provide an additional 2 turns of game time

The Chaos players must prevent this from happening, allowing their ship and it’s cargo to escape the system.

Each team will have a secret objective as well, to add a little spice to the game.

Teams

The game will revolve around two teams of three players.

Imperial

  • Inquisitorial Lancet Hereticus space marines intent on getting revenge on the Ferrymen
  • Sisters of Battle team tasked with retrieving the “Saint”
  • Imperial naval troopers tasked with knocking out the Geller Field Generator

Chaos

  • Ferrymen Plague marines who need the “Saint” to enact a terrible ritual
  • Captain Mad Claw and his pirates who wants his ship kept in one piece
  • First Mate Chaos mutant Head Bustin Billy who wants to destroy as many Imperial boarders as possible

Set Up

The board will be relatively small and full of tight corridors with lots of twists and turns. I want it to feel like the claustrophobic interior of a sprawling spaceship. The Imperials will deploy in the upper right of the board while the Chaos pirates can deploy anywhere else.

Not only that, but the Chaos players will get two objective tokens representing the saint, one real and one false.

Imperials go first.

Scenario 2: Under Hive Raid

The second scenario is based more along the lines of the inter gang conflicts of the underhive. It is an asymmetric scenario that should last for just over an hour. I have just finished painting my Adeptus Arbites kill team and wanted to use these 40K lawgivers in a game. The key here was to have an asymmetric game. The outnumbered lawmen on one side and the chaotic, are they allies are they not, gangers on the other.

Setting the Scene

The under-hive gangs of Kasanaan Tertius in the southern hemisphere of Helios Magna are revolting. The Adeptus Arbites have sent enforcers to stamp down on this insurrection. We are playing one such encounter. A small team of Arbites attempts to capture/kill crews of gangers hoping to make their escape from the kill zone.

Objectives

The game lasts for 4 rounds with the players split as follows. Two Arbites players working together, each with a team of 2 stronger operatives. Four or more gang players working individually, each with a crew of 3 weaker gangers. Scoring will work differently for each.

Arbites (collective points)

  • 1 point for each ganger taken out of action by Arbites personnel

Gangers (individual points)

  • 2 points for each crew member escaping off the opposite side of the board
  • 1 point for each Arbites taken out of action by your team
  • 1 point for each opposition ganger taken out of action by your team

Set Up

The battlefield will be set up to represent the warren of industrial tunnels that make up the under hive. Gangs will set up on the right hand edge, hoping to escape from the left side. The Adeptus Arbites will set up in the left hand half of the board ready to capture as many gangers as possible.

To add additional flavour the players will name their gangs and Arbites fire teams.

For those who play space weirdos the stats for this game are as follows:

If an Arbites moves next to a downed/staggered model and takes an action – it is manacled and considered out of action

Final Thoughts

I’m really looking forward to running both of these new scenarios at Martycon 2025. They are both filled with opportunity for emergent narrative to explode. Faction rivalries and player inventiveness is bound to make for memorable games.

Once the dust has settled I will report on how they went and any lessons learned.
