Images of all the new Horus Heresy rules are here, and it looks like the game may be changing a lot from its roots.
Before we go any further, we want to say, take all of this with some salt. They seem extremely solid, but they are rumors, so this means they could change or might not be 100% right. So, don’t get too worried just yet if you aren’t a fan.
With that said, there are a lot of rumors we’ve seen before, so let’s check those out first, then get into the new stuff.
Here’s the most up-to-date list of new Horus Heresy Rules & Product Leaks. Click on the gallery above to see new Horus Heresy models and rules rumors!
Liber Astartes & More New Horus Heresy 2.0 Rules Leaks
Here are a ton of new rules that look to be from a playtest version of Horus Heresy spotted on the 30k Reddit.
Seems like the red books may be getting replaced with this new style-book, the first apparently dubbed the Liber Astartes.
There were quite a lot of the Phase 3 playtest rulebook leaked, which you can view at the gallery below. We will cover some of our favorite new rules rumors below in detail.
New Horus Heresy Rules: Reactions
These new rules seem to be a more encompassing style of Overwatch that looks to keep games more engaging no matter what may happen during either player’s turn.

The first page is the general rules for what reactions are, and the page above details different types of these new reaction rules.
Horus Heresy Armor Values Rules
Anyone that was worried about armor values going away after seeing the Dreadnought rules leak, can breathe a sigh of relief as it looks like Vehicles, in general, are going to function similar to how they did in the past.
Well sort of…
From this leak, however, it seems like Weapons may function a bit differently on vehicles now.
Dont Tell the Emperor, but there’s Psykers (still/again)

Primarchs In Horus Heresy
Part of the early rumors were that Primarchs were losing Lord of War status among other things. These new leaks seem to confirm changes to the mightiest of all save the Emperor and Horus.
To Hit & Wound Charts:
Another throwback to 7th Edition, the to hit and wound charts appear to still be in Horus Heresy.
New Horus Heresy 2.0 Legion Rules Rumors

RUMORS: New Horus Heresy Primarch & Character Rules Spotted!
These new rumors were spotted on Imgur, and show all kinds of new stuff! Again, they are from the phase 3 playtest which seems to match the other rules rumors we have seen already, so they could change once they are finalized…

Pretty much just awesome all the way around.

Either way, new rules and even just one new Horus Heresy starter box set at the bare minimum would be a great thing to see. Here are all the latest rumors on the upcoming rules updates and new models for the Horus Heresy system.
GW Reveals New Space Marines Tank For Horus Heresy
Warhammer Community talked about a new tank in their trailer for the upcoming Horus Heresy game revamp. In the image below it appears to have a turret-mounted battle cannon, with a shorter co-axial weapon, one traversing hull-mounted gun above the port treads, and one behind the lower treads in the fore of the hull.
The Horus Heresy is the game to play if you love war machines clashing on the grandest possible scale. From the Spartan Assault Tank to the Legion Sicaran Battle Tank, mighty vehicles were mainstays on the front lines throughout the Heresy, giving treadheads plenty to enjoy. But we don’t recognise this tank – what could it be?
Here you can also see a pintle gun mount on the top turret hatch as well.
Rumor is that may be the fabled Kratos Battle Tank mentioned in Horus Heresy Book 8 as the precursor to the Predator tank. Since it bears more than a passing resemblance with the Sicaran, perhaps it will a dual box kit with the Sicaran tank that recently went on last chance to buy over on Forge World as well…
Sicaran & Kratos Tank Possibilities
These new rules rumors were spotted on Imgur, and show what appears to be the Kratos with the same weapon configuration as the mystery tank from the HH trailer! Again, they are from the phase 3 playtest which seems to match the other rules rumors we have seen already, so they, however, could change once they are finalized…

We also recently heard this rumor as well that seems to support this document:
Most vehicles are now squadrons, including Deredeo Talons, Sikarans, Whirlwinds (including Scorpius), all Sicaran variants, Predators (in up to 5), Cerberus, and Typhons
Plus according to other sources, the Kratos is a new release kit that will be coming after the rumored release of the Horus Heresy starter box this June.
- Deimos Pattern Vindicator – £39
- Kratos Battle Tank – £52.50
- Land Raider – £52.50
- Land Raider Spartan – £60
- Contemptor Dreadnought – £35
- Space Marine Tactical Squad + Rhino – £57
- Deimos Pattern Rhino Suqadron – £87
- Deimos Pattern Predator Squadron – £107
- Space Marine Auxillary (details unknown)
From the looks of it, this mystery tank may just be the Kratos, however, its’ exact size in miniature form still remains to be seen.
