A Closer Look: Astral Adventure Boxset
4 months ago – Tue, Apr 14, 2026 at 06:09:45 AM

Greetings, Astral Citizens!

After looking at the Astral Citizen Pack in our previous Closer Look update, today we are taking a look at the Astral Adventure Boxset! If you want an adventure experience like no other for Ion Heart, all neatly packaged up in one box, then this set is for you! Let's take a look at what you get inside: 

6 Mech Miniatures

The stars of this boxset are the 6 Mech minatures, each one styled after one of the core 6 species you can play as in the game. These can be used as your player pieces, allies or even enemies, depending on what stories you are playing. We are incredibly excited to bring our first set of miniatures to life, and want to make sure you can too! That's why, alongside the physical minis, we have included free STL files for the Mechs so you can print even more!

We also want to give a shoutout to the fantastic team at War Scenery (who you can check out here) who made these fantastic sculpts. It's been amazing to see Ben's designs be formed into 3D, and we can't wait to see them on the tabletop. 

For a closer look at the minis, we've rendered out some 3d turnarounds below for you to check out: 







Adventure Booklet

So what will exploring using these minatures? The box set includes a full adventure in a softcover booklet, filled with multiple encounters, mechs, items and rewards for your players. This easy-to-run story will have you set up and playing the game in no time at all, including preset characters for all your players if you want to jump straight in with no player prep. 

Card Deck

To make the adventure even smoother to run, we've included cards for every element you'll find in the box set and its adventure. This includes:

  • New enemies
  • Weapons and items 
  • Allies
  • Mech Cards for the included minatures

Token Sheet

Your Mech miniatures won't be alone on the map; we've also included a token sheet for all the enemies, hazards and objectives you'll find in the adventure booklet!

To be clear, as it is a question we've seen pop up a few times - the cards and tokens are unique to this box set and are not duplicated in the Card Packs or Map and Token Pack.

3 Days Left!

We have only 3 days left before the campaigns ends, so make sure to back before it closes!

Thank you again everyone - we can't wait to explore the galaxy with you all!

A Closer Look: The Astral Citizen Pack
4 months ago – Mon, Apr 13, 2026 at 07:38:45 AM

Greetings, Astral Citizens!

After looking at the ION Heart Card Deck in our previous Closer Look update, today we are taking a look at the Astral Citizen Pack! There’s so much to delve into here as it filled to the brim with all kinds of Ion Heart goodies that make you feel like a part of its world, so let’s get started:
 

The Nephilim Net Book

We wanted to provide a small book which feels like it is straight out of the world of Ion Heart and something your Pilots would feasibly have on them. With the Emergence War breaking out suddenly, this threat was truly alien to all, and Pilots needed a guide on this new and strange enemy. This is why the Nephelim Net is styled as a military service manual for tackling this now-defeated enemy. 

Although the Nephelim have been defeated, their remnants still pose a threat. The book will include story seeds for adventures where you will go toe-to-toe with the Nephilim and fight to prevent them from regrouping. With a whole host of Nephelim stat blocks too, this book will provide everything you need to face the Aegeic Galaxy’s greatest foes.  

Aegeic Flora and Fauna Handbook

Exploring the galaxy will take you and your friends to a whole host of different planets, each with its own unique ecology. This  24+ page softcover book acts as a guide to the wild and wondrous worlds of the Astral Union. This is designed to feel like a traveller's companion, filled with facts and points of interest, as well as advice on how to keep safe no matter where you go. 

Filled with story inspirations for different ecologies, stat blocks for megafuana you may discover, and items for interacting with the environmental wonders of the galaxy, this book is your perfect guide to exploring the natural world. 

Metal First Player Token: Medal of Service

Another echo of your Pilot’s past is the metal first player token, forged to represent a medal of service in the Astral Union military. When you’re holding it, will you fight to the last like in your past? Or will you choose a different path? 

Postcard Set

A set of 5 art postcards showing off the world of Ion Heart. Perhaps send a postcard to a friend from your Pilot, and tell them all about your adventures. 

Dice Bag

Gather up your dice and store them in this bright pink and blue bag so they never go astray!

Iron On Patch

The piece of art for this fabric patch has become a team favourite as well as the players! This cosy patch of Mech's around the campfire is ready to attach to jackets, backpacks and blankets with a simple iron-on adhesive.

Art Print

An exclusive A5 art print perfect as a piece of peaceful wall art. Have a favourite piece of art you’d like to see hung up so far? Drop a comment below and let us know which is your favourite so far, or something you’d like to see!

Sticker Sheet

If you’re like me, you love to cover your notebooks (of which I have too many) in as many custom stickers as possible. This A5 sticker sheet will let you do just that!


Ion Heart Pen

Never lose your RPG pen again with this brightly coloured Ion Heart Pen. Keep detailed pilot logs, mark up your character sheet, and take notes as you explore the galaxy.

Luxury Fabric Tote Bag

A bundle as big as this would be remiss if it didn’t have something to carry it all! This durable, soft fabric bag with a zippable top is perfect for carrying all your Ion Heart books as well as all the goodies you get in this pack!

A Closer Look: Card Packs!
4 months ago – Fri, Apr 10, 2026 at 06:54:08 AM

Greetings Astral Citizens!

After looking at the Map & Token Sheet in our previous Closer Look update, today we are taking a look at the ION Heart Card Deck!
This double card deck contains over 100 cards for all your gameplay needs. It includes two very different decks: the Encounter deck, and the Armoury deck. Let’s delve a bit deeper into each one:

The Encounter Deck

Need to rustle up a quick encounter? This deck allows you to deal out an adventure in seconds, perfect for creating quick Encounters on the fly, or as inspiration for making your own stories.

  • Enemies: Populate your Encounters with unique enemies with clear and quick reference cards.
  • Objectives: Need a focus for your players in an Encounter? These objectives will provide rewards and ideas for different styles of gameplay you can create in an Encounter.
  • Encounters Seeds: Need some inspiration? Deal an Encounter seed and get inspired for Peaceful, Protective and Dangerous stories. 

Use this deck to make sure you never miss a beat and always have an Encounter up your sleeve!


The Armoury Deck

This deck is designed to make outfitting your Mech for whatever challenges you may face a fast and easy process. Try out new loadouts, reward players with new gear, and experiment with tonnes of unique combinations. Inside this deck you’ll find:

  • Weapon Cards: Melee and Ranged weapons ready to fight back against your enemies
  • Auxiliary Cards: A set of Aux systems to plug into your Mech to help you out in difficult moments
  • Mod Cards: Switch up how your weapons and auxilliary systems work, or plug mods directly into your Mech’s chassis. What combinations will you create?
