Warhammer previews Spartan Prometheus and Falchion tanks for Horus Heresy

Warhammer Community’s Sunday Preview on May 17 put two Horus Heresy heavyweights front and center: the Spartan Prometheus Assault Tank and the Falchion Super-Heavy Tank Destroyer. Both were flagged for pre-order next week, with rules available in Liber Astartes: Loyalist Legiones Astartes Army Book and Liber Hereticus: Traitor Legiones Astartes Army Book, a neat reminder that these are not just display pieces but battlefield kits for both sides of the Age of Darkness.

For painters, the Spartan Prometheus is the bigger headline. Warhammer has already said it is heading to plastic, which makes a real difference for anyone who has wrestled older resin kits into a clean army project. The tank can carry entire squads of power-armoured or Terminator-armoured warriors, and it can be fitted with gravis heavy bolter arrays or laser destroyers. That puts it squarely in centerpiece territory: broad hull panels, visible transport access points, and enough weapon choices to reward careful planning before glue ever touches plastic. The old Spartan Assault Tank already had that presence; the Prometheus version pushes it further into a build that invites magnetizing, battle damage, and a serious weathering pass.

The Falchion comes in as the pure gun platform. Its main weapon is a neutron-wave cannon, backed by optional laser destroyers, gravis heavy bolter batteries, or lascannon arrays on the sponsons. That kind of loadout makes it the sort of super-heavy that can anchor an army list and dominate a shelf at the same time. For the hobby bench, it is also exactly the kind of kit that rewards crisp trim work, panel line definition, and patient edge highlights, because there is nowhere for weak paint work to hide on a hull this large.

The preview was not only about tanks. Eisenhorn: The Omnibus is coming in French paperback, collecting Xenos, Malleus, Hereticus, The Magos, and three short stories, while the ebook lands in the Black Library app on June 6, 2026. Warhammer TV also lined up a Battle Report pitting Kragnos against Cogforts, a Weapons and Wargear episode on realmstone, and a Painting Desk segment with guest painter Drew Paliès. White Dwarf 517, a scenery showcase issue packed with building tips, is headed into the Warhammer Vault too.

Warhammer also kept Armageddon in the mix, teasing more coverage of the boxed set tied to the new edition of Warhammer 40,000 and Ghazghkull Thraka’s return. But for Age of Darkness collectors, the real story was the same one at the top of the page: a plastic Spartan Prometheus and a weapon-bristling Falchion are moving toward pre-order, and both look ready to become the next big Horus Heresy builds.
