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.

I will be picking this up solely for the lore and art, cuz I’m that kind of nerd.

The margins for making Warhammer products must be such that it’s worth putting these out. I’d love to get a sense of how much money these things make.

Slightly surprised by this as the Horus Heresy seems like one of the less "game-able" parts of 40K (I know, technically 30K), on a TTRPG level.

From my perspective, I agree and suspect that's what the second PC is to assist with. You could also slip in troupe play, I suppose.

I never got to play it, but I thought Rogue Trader was actually genius. I saw a lot of potential in that set up, including satire because nothing good ever came out of tossing a chaos artifact into your cargo bay.

I feel like it's all Cubicle 7 should do at this point: Warhammer RPG books.

That's pretty much what they do.
They still have the Dr. Who license, don't know if they released anything new recently though. They still have some 5e products in their shop (two products even in Q1 2025). But it's probably a safe bet that 75%+ of C7 is Warhammer x...

So Cubicle7 is truly just "That Other Warhammerr Company" at this rate. But I love Warhammer so mighty pleased, especially because these are all concurrent product lines apart from those older PDFs.

WARHAMMER 40,000
1. Wrath and Glory with D6 pools
2. Imperium Maledictum with D100 percentile
3. Horus Heresy

WARHAMMER FANTASY
4. WFRP 4th Edition with D100 percentile
5. The Old World with D10 pools

AGE OF SIGMAR
6. Soulbound with D6 pools

And still selling PDFs of older D100 Dark Heresy, Rogue Trader, Deathwatch, Only War and Black Crusade.

I’m not saying either approach is right or wrong, but it sure is a contrast with what WotC does with D&D.

Ouch. I love Cubicle 7 and think they make some of the best gaming products out there - ever since AIME.

However boy are they spreading themselves thin. 3 systems all set in the 40k universe? I can understand it with the fantasy side as WFRP4e is nearing the end of its edition cycle with 20+ books. But Imperial Maladictum has barely got started. One core core book, one starter set and the inquisition expansion. I fear they don’t have the resources to keep 5 Warhammer lines going well.

But wasn't one of those 40k lines taken over from another publisher (Wrath & Glory from Uliesses Spiele). It started out a bit more cartoony than most of us would like, it seems that has changed a bit over the years. Imperium Maledictum is C7s own D100 take of 40k, the HH RPG is 30k. It wouldn't surprise me at all if we eventually also get a Necromunda RPG... It's still less then the 5 40k systems we had under FFG...

What @eyeheartawk said, this might just be licensing requirements that GW sets to continue running the RPG sublicense at all. From a GW perspective it isn't a bad deal, as it gives them a channel for potential new plastic crackheads that flow in from the RPG side into the particular GW game. Funny thing is, I already flowed into 40k, back when it came out in '87 from RPGs...

And I think they did confirm they are also doing a Warhammer RPG book about The Old World as well!

Well, I guess that Chaos book for Soulbound won't be coming anytime soon. And at this rate, it feels like 40K/Fantasy is their main focus while letting Soulbound stagnant a bit.

This is my reaction. Soulbound is a great system, but instead of supporting it with more content they are launching a new system. Disappointing.

Champions of Chaos is still coming for Soulbound.
