Games Workshop unveils final Imperium faction packs for 11th edition

Games Workshop closed out the 11th edition faction-pack rollout by turning to the Imperium, the human and human-adjacent armies that hold the line across the setting. The final release completed a staggered reveal that began with Space Marines, moved to xenos, then Chaos, and ended with the Imperium on June 11, 2026.

For players, the headline is not just that more armies got downloadable support. It is that the new edition’s army building is built around Detachment Points and Force Disposition, which means the detachment picked for a force now feeds directly into how that army plays on the table. The Imperium packs cover a wide spread of factions and sub-factions, including Astra Militarum, Adepta Sororitas, Adeptus Mechanicus, Imperial Knights, Adeptus Custodes, Imperial Agents and related forces, giving each camp a fresh menu of battlefield identities to sort through before the first game of the new edition.

The Astra Militarum list shows how broad the options have become. Alongside familiar archetypes such as Armoured Infantry, Combined Arms, Mechanised Assault, Siege Regiment and Steel Hammer, Guard players now have choices like Abhuman Auxiliaries, Bridgehead Strike and Designation Force Reconnaissance. Sisters of Battle get their own distinct lanes as well, with new detachment identities such as Chorus of Condemnation, Sacred Champions and Sanctified Orators. Adeptus Mechanicus players see a similarly wide spread, with cohorts and formations including Cohort Acquisitus, Lords of the Forge and Luminen Auto-Choir. Imperial Knights also receive a strong slate of identities, including Dominus Foebreakers, Questor Forgepact and Throne-bonded Outriders.

The practical read for returning players is simple: check the detachment first, then build the list around it. Games Workshop said the new edition launches on Saturday, June 20, 2026, that armies get 2 Detachment Points in 1,000-point games and 3 in 2,000-point games, and that current codex detachments remain valid at launch. Back in April 2026, the company said there would be more than 70 new and updated detachments, and it also said detachments now affect missions, making the choice relevant for matched play as well as army construction.

With the Imperium release now in place, the full 11th edition framework is finally visible. Space Marines, xenos, Chaos and now the Imperium have each had their turn, and the launch no longer looks like a single rules drop so much as a deliberate transition into a new army-building era.
