Games Workshop Opens Horus Heresy Siege Assault Box Pre Orders

Games Workshop kicked off a weekend pre order window on 27 December that centered on new Age of Darkness releases and supporting fiction. The headline product was the Siege Assault Battle Group box, a bundled release that brings together new Cataphractii Terminators, a Breacher Squad of Space Marines, and a Leviathan Siege Dreadnought, accompanied by multiple Legion transfer sheets. The box was offered as a limited quantity item available while stocks last, with the individual kits slated to be sold separately at a later date.

The bundled box is aimed at players and collectors building Horus Heresy collections who want immediate access to coordinated units and transfers. As a single purchase it consolidates several models and markings into one package, so buy the box now if you want the complete set and want to avoid the risk of missing out. If you only need one kit, plan to wait for the later separate releases, but expect those to appear after the limited box window closes.

Black Library supported the drop by opening orders for print on demand hardbacks of four recent Gaunts Ghosts novels. The titles available in this ordering window were Blood Pact, Salvations Reach, The Warmaster, and Anarch. These PoD hardbacks carry standard print on demand lead times, so expect some delay between ordering and delivery rather than immediate shipping.

In addition, a selection of Warhammer 40,000 terrain remained available through Made to Order until 12 January 2026. Availability is region specific, so check your local store and online region options to confirm whether particular terrain pieces can be ordered in your area. The Made to Order window gives modellers a chance to pick up terrain items that are not regularly stocked, but you must act before the January cutoff to secure items in this cycle.

Practical next steps are straightforward. Check your local store and the Games Workshop online store for stock updates and ordering windows. If you want the full set of Horus Heresy models and transfers now, secure the Siege Assault Battle Group while it is still listed as available. If you want individual kits only, wait for the separate releases but be prepared for a later purchase opportunity. For Black Library print on demand volumes budget for typical PoD lead times when planning gifts or collection additions. Finally, confirm regional availability for Made to Order terrain and place orders before 12 January to avoid missing the current window.
