Horus Heresy Tallarn Rules, Raven Guard Lore, and Grot Week Day 4 Keep Warhammer Busy

Games Workshop put out a nicely varied batch of updates this round. So, there is something here for big Horus Heresy Tallarn fans, lore readers, and Ork troublemakers alike.

The Tallarn material is the heavy hitter, because it adds both narrative depth and actual game support. Meanwhile, the Raven Guard archive drop and the latest Grot Week tease keep two very different hobby audiences fed.

Horus Heresy Tallarn gets the kind of campaign support Horus Heresy vehicle players were hoping for

The new Journal Tactica: The Battle of Tallarn looks like a proper attempt to make Tallarn feel huge, toxic, and mechanised in equal measure. First, it revisits the opening of the campaign, from orbital bombardment and viral attack through the Iron Warriors invasion.

However, it does not stop at the disaster itself. Instead, it follows the Tallarn Reborn as they rise from subterranean bunkers and begin hitting back with stockpiled Imperial war materiel. Meanwhile, the book broadens the conflict by pulling in Legiones Astartes companies and stranger outside forces. That matters, because Tallarn should feel like a sprawling war magnet, not one isolated battle. On the hobby side, the supplement includes organisational diagrams, colour schemes, markings, and maps, which is exactly the kind of material that helps campaign projects feel grounded.

Then the rules section adds a narrative ambush mission, where Solar Auxilia tanks disguised as wrecks hit an Iron Warriors convoy at close range. That already sounds like the right sort of dirty Tallarn warfare. More importantly, the new Armoured Spearhead Mission pack pushes vehicle warfare even harder with fresh Detachments, Prime Advantages, and a scoring system that rewards killing enemy vehicles with your own armour.

So, this is clearly not just “more missions.” It is a rules package built to make tank battles feel like the point. The book also adds toxic environment rules, Cohorts Vagus wandering automata, command versions of the Dracosan and Spartan Prometheus, plus updated Rapier and Charonite Ogryn profiles tied to the new kits. Altogether, it reads like the kind of supplement that can anchor a whole Tallarn campaign weekend.

The Raven Guard archive drop adds welcome context before the Legion’s darkest hour

The Raven Guard piece is much smaller, but it still has real value for Horus Heresy lore fans. This week’s free pages come from The Horus Heresy Book Three: Extermination, first published in 2014, and they focus on the XIX Legion before Isstvan V breaks them apart. So, the article frames the download around their early battle honours during the Unification of Old Earth, their campaigns beside the Luna Wolves, and the discovery of Corax. It also promises details on the Legion’s structure and disposition as they prepared for the coming disaster.

That is a smart place to stop, because it catches the Raven Guard at the edge of their defining tragedy. Meanwhile, the post also gives a neat hobby nudge by linking MkVI “Corvus” armour directly to Corax and suggesting the MkVI Tactical Squad as a natural starting point. So, while brief, this is exactly the kind of archive release that makes old Black Book material feel alive again.

Another Grot joins the slow-roll reveal with the right kind of comic menace

Day 4 of Grot Week keeps doing what this mini-campaign has done well all week. It takes tiny reveals and gives them just enough character to stick. This time the spotlight falls on a grenade-wielding Gretchin, presented as another victim of the rubbish jobs Orks hand out, from mine clearing to soaking up enemy fire. However, the article also leans into the upside of that miserable existence. Grots are good at looting, and this one has clearly “found” a stikkbomb somewhere questionable.

So, the model lands as exactly the kind of chaotic little nuisance Ork players love. It also helps that the post reminds readers the full Warhammer 40,000: Armageddon box reveal follows right after Grot Week ends. As a result, the tease works less like a standalone reveal and more like one last nudge before the bigger show.
