The red-hot heart of Mars is pumping out new reinforcements, and the Mechanicum has some serious steel rolling into battle for Warhammer: The Horus Heresy.
If you’re running a Taghmata force, you’ll want to make space in your storage crates—because between brutal artillery platforms, tank destroyers, jump-jet berserkers, and towering siege bots, the red planet is not messing around.
Karacnos Assault Tank
Mechanicum artillery just got meaner. The Karacnos Assault Tank takes the tried-and-true Triaros chassis and swaps troop transport for a belly full of radiological mortar tubes. It’s heavily armoured on all sides, making it a nightmare to shift, and its payload doesn’t just blow things up—it contaminates. Lingering damage over time makes this tank especially dangerous for infantry bunkers and light vehicles that can’t afford to sit in the open.
Krios Battle Tank / Krios Venator
The Krios is your all-purpose death wagon—fast, tough, and packing either a lightning cannon or an irradiation blaster, depending on your vibe. The lightning cannon is a crowd-pleaser, vaporizing whole squads with a single blast. If you’re more about melting faces at close range, the irradiation blaster trades range for sheer brutality.
Feeling like hunting bigger game? Build the kit as a Krios Venator instead. This variant sports a pulsar-fusil, perfect for putting holes in other tanks—albeit at shorter ranges. All Krios variants come with volkite sponsons too, for that extra spicy side-dish of firepower.
Thanatar Calix Siege-automata
This one’s for when you want to bring the big guns—and the big fists. The Thanatar Calix is Mechanicum’s equivalent of a Leviathan Dreadnought, armed with a shoulder-mounted Sollex heavy lascannon that can flatten enemy armour from across the board. If someone thinks they’ll outflank it? Surprise—its graviton ram will turn them into paste. It’s a walking, stomping piece of overkill. And we love it.
Ursarax Cohort
Think Thallax, but even nastier in close quarters. Ursarax are jetpack-enhanced shock troops—half-man, half-machine, all carnage. They’re fast thanks to their Utan boosters and pack either twin lightning claws for maximum shred or power fists if you prefer brute-force clobbering. They’re ideal for flanking, taking down elite infantry, or just flying headlong into the enemy’s backline.
Farsight: Blade of Truth
It’s not just Mechanicum that’s getting love this week—Commander Farsight returns in a new novel by Phil Kelly. Blade of Truth explores the time between Farsight’s earlier campaigns and his reappearance in the Second Agrellan War. Expect new T’au tech, Tyranid trouble, and that classic blend of tactical brilliance and existential dread we all associate with O’Shovah. Pre-orders are dropping soon in hardback, eBook, and audiobook.
In short: Mars is fully locked and loaded. Whether you need line-breaking artillery, tank-hunting monsters, or jump-jet murder machines, the new wave of Mechanicum units is a must-have for Heresy players looking to dial their army up to 11. And for lore fans, Blade of Truth offers a perfect way to dive deeper into one of the T’au Empire’s most iconic heroes.
