This Week Belongs to the Technologically “Advanced”

Whether you’re drawn to Mechanicum in Age of Darkness or want to defend against Chaos in The Old World with Grand Cathay, this pre-order week is all about what we love: new units, new options on the table, and beautiful models to paint.

Warhammer: The Old World – Defenders of the Great Bastion Army Reinforcement Set

Grand Cathay is sending reinforcements. And this isn’t just “a few extra models” – it’s a package that can define the style of your army: shooting, discipline, and Bastion defense.

The Reinforcement Set adds a mix of units to the game, capable of handling both masses and ranged targets. You’ll get:

Warhammer: The Old World – Arcane Journal: The Breaching of the Great Bastion

For Cathay players, this is a “must-have.” The Arcane Journal adds rules, lore, and new gameplay options – exactly the type of book that opens your army in depth.

It includes rules for key units (Astromancers, Crane Gun Teams, Iron Hail Gunners, Peasant Levy) along with new story content about the Land of the Dragons, its magic, and the conflict around the Great Bastion. It also provides new army composition options (including “special” themes) and a scenario for replaying the Battle of Nan-Li.

The Horus Heresy – Myrmidon Destructor Host

“Smart people run away…” – Myrmidons are walking weapon platforms. And when they’re on the table, the whole battlefield starts looking more dangerous.

This boxed set builds six Myrmidon Destructors, offering super flexibility: either two units of three (more board coverage) or one larger unit (more “brick” feeling). Each model can carry either a darkfire cannon or irradiation engine, and all come equipped for close combat (because, Mechanicum, right?).

The Horus Heresy – Skitarii Battle-Pilgrym Marshal

When Battle-Pilgrims form your core, you need someone to lead them. The Marshal is a field commander, representative of the Fabricator General – and a model you can customize exactly how you like.

The Marshal is highly customisable: multiple heads, more ranged weapons, more melee options + servo-skulls that give the miniature exactly the right “authority” vibe. He’s a hero/commander who looks great even if painted quickly – and can handle extreme detail if you want to go all out.

The Horus Heresy – Skitarii Battle-Pilgrym Corpus

The Marshal is great… but without a unit, he’s just a lonely commander. The Corpus is the core building block of Skitarii Conclaves – and a beautifully “grim-tech” unit.

The set contains 16 miniatures. In gameplay, you can field them as 2 squads (each 7 Battle-Pilgrym + Ordinator) or one larger unit. Each Pilgrym carries a voltlock arquebus – a refined volkite-style weapon that fits perfectly in Heresy.

Stylistically, you can also choose Loyalist or Traitor – so you can tune it exactly to your side in the conflict.

The Horus Heresy – Vultarax Stratos-Automata

When even long metal legs aren’t enough, aerial superiority enters the field. Vultarax is a fast scout, relic hunter – and a problem for anyone who stands in the wrong place.

Vultarax moves on gravitic impellors and thrusters, flies ahead of the main force, scouts archeotech… and then destroys the target before anyone can say “that’s a really nice model.” Armed with a arc blaster and phosphex warheads, this is exactly the kind of stylish yet uncompromising Mechanicum firepower threat.
