Cubicle 7 Announces New Horus Heresy RPG for Warhammer

Cubicle 7 is expanding their line of Warhammer TTRPGs with a new RPG set during the Horus Heresy. During last week's Warhammer Relics announcement event, Cubicle 7 announced that they were developing a new Horus Heresy RPG, set to launch in 2026. The Horus Heresy is one of the defining events of Warhammer 40K lore, and saw the famous Space Marine legions of the Imperium of Man engage in a bloody civil war. The Horus Heresy ended with the mortal wounding of the Emperor, which led to him being placed inside a massive supercomputer sarcophagus known as the Golden Throne, and led to the extreme stagnation of the Imperium that lasts until the present day.

One notable twist in this new RPG is that players will create two characters - a primary character that acts as a Consul within a Space Marine corps, and a secondary character that holds a specialty occupation. Players can swap between characters when their respective particular skills are needed.

Pre-orders for The Horus Heresy: The Roleplaying Game will start this summer, with a core rulebook and starter kit going on sale in 2026.

It's a genuinely sick as hell concept for an RPG, basically FTL in tabletop form with the fleet management stuff. Having two characters, one a space marine consul (chaplains/librarians/champions/etc) and the other a mortal to do skill stuff, that's also rad.
 



Champions of Chaos is still coming for Soulbound.
I hope so. I get that it's Chaos and that means doing a book that gives ya all four chaos gods and character options so they gotta make sure it does everybody's preferred choice right. I'm just hoping that since we got playing le dragons in Soulbound, they decide to go nuts and give us THIS as a playable Chaos choice:

I ... might buy to in this. I've had mixed feelings about the C7 warhammer stuff so far, but the double-PC thing has me intrigued. A bit reminiscent of what FFG did with Only War, your main PC and (in for guardsmen at least) your very in-genre offsider who was expected to die a lot. It's an interesting idea, and it makes me thing they're willing to be a bit innovative and experimental.

How you set up a PC party seems .. tricky though. I've been mulling very distantly over a Horus Heresy game myself (planning on using a tweaked version of the Mutants and Masterminds rules, with restricted options based on your PCs legion, specialisation, equipment etc rather tat full freeform point buy, and with a more abstracted Range system using melee/close/long etc bands rather than a D&D-esque grid), and unless you pick PCs from the same legion (and c'mon, players will want to play astartes from their favourite legion, plus variety is good...) it's hard to find group stick. The blurb talks about how PCs will be officers - consuls, librarians and so on, which implies that they're likely to be of the same legion? Officers have command responsibilities, and won't be running around in small groups with counterparts from other legions. It's a tricky one. If could be centred around Malcador's grey shields I suppose, but then you have little scope for having your high-ranking marines actually command anything. Or maybe they can be from different legions, but the backup characters are to allow one player to play the Astartes character in stints while others play the supporting cast? I'll be interested to see how it works.

The idea for my campaign was going to be the ceremonial guardians of a small shrine commemorating a very old battle. One honour guard representing each of the legions that fought there, each long isolated from their legion on their vigil. Very obscure, very isolated, very out of the way, so that even traitor legions might have a representative there who didn't turn with the rest of their legion (yeah, the Word Bearers would be a bit tough to justify...) Gives me a varied PC group, and reasons they're operating together.
 


Think it of playing a set of Black Adder and Baldrick...

The Chapter Serf that's attached to your Space Marine will probably be holding the target during practice:
Yeah, I understand that, it’s more about how you manage group creation if one player wants a White Scar, another created an Ultramarine, then there’s a Salamander or something. Why are these high-ranking officers from different legions (which are probably located in very different parts of the galaxy, given that the physical distance between legions is a massive plot point through the Heresy), running around in a small group together rather than commanding forces of their own legion? Theres no Deathwatch in this era to serve that narrative purpose getting legionnaires from different legions to work together. What’s the storytelling premise, I’m trying to get at. You can of course restrict your PCs to one legion at character creation time, but it does seem limiting.

I think it might come down to just how high ranking they are. Plenty of examples of fragments of different legions working together due to various factors, and also have potential for loyalists from traitor legions and vice versa, but generally they were typically a couple of high ranking officers and many lower ranking as such.
