Latest Updates from Our Project:

30K Stretch Goal Unlocked! - Community PDF Expands with Votivian Shards
5 months ago – Tue, Mar 24, 2026 at 11:19:41 AM


We truly are blasting off into the stars to explore at a record rate, and with another stretch goal unlocked, the community PDF grows even bigger!



We'll be expanding the tales in the ARK by delving into the Arkivist's encounters with a series of mysterious artefacts scattered around the Aegeic Galaxy known as the Votivian Shards.



These strange mineral shards come in all shapes and sizes and cause strange anomalies in time and space in their vicinity. AU scientists are still unclear where these powerful anomalous pieces of material have come from, or why they behave in such strange ways, some theorising they are relics of a long extinct species now lost to the past, whilst others believe they may have slipped in time and been sent back from a possible and unstable future.

What strange encounters have the Arkivists had with the shards? Can they shed any light on their mysterious origins and effects? Find out in the ARK!

Our next stretch goal is going to bring that telltale anime glint to Ben's gorgeous cover designs with some special Spot UV varnish! If you want your books to shine bright, please give the project a share and help us smash this next goal 🌠


Thank you again to everyone supporting us. This has truly been an incredible first day!

The next goal we are chasing is really exciting, we will be adding a whole new Chapter to The ARK, our community PDF that all backers will get for FREE. When we hit this new goal we'll delve a bit more into the detail of what this chapter contains...



Thank you to everyone for making this launch one to remember!

Factions and Enemies - What threatens the newfound peace? ☮️
5 months ago – Tue, Mar 17, 2026 at 10:03:10 AM

The Aegeic Galaxy in which ION Heart is set is a big place, full of lots of different characters, all with their own beliefs and ideas of how the galaxy should be. 

When we’re designing Factions for the world of ION Heart, we’re always thinking about how they fit into the bigger picture and how they work on their own. There’s four factors we think about when working on the factions for the universe:

  • What do they want from the galaxy? 
  • How will they look to players on the outside? 
  • How can gamemasters use them to tell fun and engaging stories?
  • Do they fit the tone of ION Heart’s world?

That last question might be the most important. Almost all of the factions you will encounter in the ION Heart Multiplayer RPG will be dynamic, and can be dealt with in ways besides outright violence. Almost all of them.

We have some returning faces from the ION Heart Solo RPG, and plenty of new ones. 

New Faction: The Children of Hakon

“The Children’s core belief is that the Nephilim are a divine punishment for all biological life in the galaxy. To find salvation, they seek to support the Nephilim in continuing their path of destruction. The end of the war hit their cult hard, but it has not weakened their resolve.”

Formerly a niche Mo’nau doomsday movement, this cult has rapidly grown in size thanks to the apocalyptic destruction that has wracked the galaxy. Trying to make sense of the chaos that has been unleashed in the Astral Union, some desperate citizens have flocked to join the cult. They ultimately want to be consumed by the Nephilim and assimilated, this being the way to become one with the god they envision is waiting for them.


Returning Faction: The Nephilim

“The Nephilim themselves are a bio-mechanical hybrid species of indeterminate origin. All that is known is they are singular-minded, violent, and impossible to communicate with. Scientists theorise that the Nephilim are constructs, built by long-forgotten creators who they ultimately destroyed before moving their gaze towards the Astral Union.”

The Nephilim are the intergalactic monsters that caused the Emergence War, and are responsible for the state you will find the galaxy currently in. There are still some pockets of these special foes you might encounter, should your adventures take an unlucky turn.

New Faction: Sectorist Autonomous Bloc (SAB)

“Inspired by Neo-Tavikian beliefs, the SAB seeks to break down national barriers and corporate influence, which they see as defining flaws of the AU. Fierce conflicts have broken out in Megacorporation-controlled systems where SAB is seeking to remove their control, and influence to return it to the people.”

This group has seized the opportunity to attempt to build a better, more just world in the wake of the Emergence War - one defined by their own ideals and beliefs. SAB-controlled zones are guarded by idealists and revolutionaries, who sometimes come into harsh conflict with their surrounding systems.



Returning Faction: The Megacorporations

“The AU has seen the rise and fall of many mega-corporations; great system-spanning conglomerates driven by the pursuit of profit at all costs. Their power has only grown after the Emergence War has ended, with lucrative military contracts having filled their coffers whilst the conflict has drained all others dry.“


The Megacorporations are a huge and colourful part of the ION Heart world. They make for wonderful villains, and wonderfully engaging storylines. Each corporation, from Noth Logistiks to Voltun Holdings, has their own hierarchy, specialisations, and ultimate (often sinister) goals.

Encounters - What challenges will you face across the galaxy?
5 months ago – Tue, Mar 10, 2026 at 08:35:33 AM

What would you expect to encounter in a roleplaying game? Some tabletop RPG players will hear clashing swords in their head, the sound of combat ringing out loud and true - but with ION Heart Multiplayer, that’s not always going to be the case. For one, laser swords sound different when they hit each other. But there’s a more important reason:

The ION Heart Universe has always been one where fighting isn’t always your only answer.



The Encounter System

The Encounter system is how your Pilot and Mech experience the world of the Aegeic Galaxy, and not all of them are going to be about Mech’s facing off in grand scale skirmishes. 

You're going to explore how your characters interact with the many worlds, the different species and their cultures, and assist with the unique problems facing daily life in the galaxy. 

In this age, fighting is less avoidable than in the distant future of the ION Heart Solo RPG, but diplomacy and charity are available options that the world of the game encourages. 

We break down Encounters in the game into three types:

  • Peaceful: This can be anything from helping a farmer herd his megafauna home, to solving a relaxing puzzle. Quite often these problems can be resolved through player discussions, roleplay, and a little bit of dice rolling. 
  • Protective: You could be exploring new worlds, keeping convoys safe during storms, protecting settlements from wildfires, or saving settlements in the wake of disasters. You can’t fight the ways of the universe, but you can help keep people safe. 
  • Dangerous: Remnants of the Nephilim, settlements under siege, and thrilling Mech vs Mech battles. This is where you face off against threats that make the universe a risky place.


Battle Maps or “Theatre of the Mind”?

All the things you will encounter can take place on a hex map to represent the world, or by using the “theatre of the mind” playstyle. Like with most things in ION Heart Multiplayer, we want you to have good flexibility, and the tools to guide your own experience in the Aegeic Galaxy.



Your Story Unfolds

How you engage with the story you find in ION Heart Multiplayer will shape your experience. There will be consequences to your actions, and the ones that you don’t make. You’ll earn battle scars, and grow stronger bonds - both between your Pilot and their Mech, and with your other teammates.

“It’s always been important to me that violence isn’t the only thing that keeps the world moving. Sometimes, like in the real world, violence just leads to more violence. In ION Heart Multiplayer, I wanted to show that a world can be changed with all manner of actions. It’s your story, and your galaxy to unite.”
Ben Alexander, Creator of ION Heart

There is no right or wrong path in ION Heart Multiplayer.

The worlds you will encounter and their citizens’ problems are nuanced and may require different approaches. Sometimes you will fight to protect the citizens of the Astral Union, sometimes you must use your mind, your voice, or your heart. 

How will you respond when faced with these problems? The Astral Union is waiting... 

POLL: What Do You Do?

“Astral debris rains down upon the space station. You only have a moment to decide how to react: What are you going to do?

  1. Use your Mech to support the structure of the facility, to aid in fleeing citizens. You risk your own safety, but you’ll make sure some will get out alive.
  2. Fly out to try and take down as many meteoric projectiles as possible before they hit the station. You can’t get them all, but you can certainly try.
  3. Coordinate the evacuation efforts. Keeping your cool and trying to help others find a way to help the evacuation efforts - if you have the nerve for it.

Make sure to vote and let us know what you'd do!



Projects We Love!

We wanted to take a moment at the end of this update to highlight some of the projects we love and are excited for on Backerkit right now! Each image is clickable and will take you over to their pages so you can find out more about these exciting projects: 

First up is Idols of the Neon Dark, a fantasy adventure about fame, teamwork, and the power of performance. Step into the role of a magical idol-warrior to combine familiar 5E rules with fresh, performance-based powers... all in a setting that feels big, bright, and (probably!) like nothing else you have played in! Whether you’re a long-time DM, completely new to the game, introducing kids to D&D, or a group of friends who love K-pop, you'll find support and fun here.
 

Legends of Akeroth is a brand new TTRPG from our friends over at Crossed Paths Press, inspired by the blue sky adventures & stories of the SNES era JRPGs such as Dragon Quest, Final Fantasy & Fire Emblem. If you love JRPGs and high fantasy fun, this game is 100% going to be for you.

Last but not least, we have Murder and Mischief flying in from Critical Kit! This multiplayer game has you playing as dimension-hopping corvids which sounds like an insanely good time to us. We are big fans of their solo game Be Like a Crow, so this multiplayer black-feathered follow-up is sure to be a real treat.
