Official Announcement

11th Edition was revealed at the AdeptiCon Preview on March 26, 2026. Games Workshop confirmed the new edition will arrive this summer, with a likely release date of June 20, 2026 based on their historical release patterns.

The Armageddon Launch Box

The starter set centers on one of 40K's most iconic conflicts: the war for Armageddon.

Blood Angels

The Sons of Sanguinius take center stage as the headline Imperial faction. Expect new sculpts and updated datasheets for the chapter known for their fury and sacrifice.

Orks

Da Orks are back in a big way! The greenskin Waaagh! crashes into Armageddon with what promises to be a significant range refresh. Given Orks' current C-tier status in the meta, this is welcome news for greenskin players.

Major Rule Changes

This change addresses one of the most common complaints about 10th Edition's objective system and should make games more visually appealing and tactically interesting.

70 New Detachments

Games Workshop announced a massive expansion of the detachment system with 70 new detachments coming to the game. This suggests a significant overhaul of army building options and potentially faction-specific improvements.

Codex Compatibility

Good news for your collection: Existing 10th Edition Codex and Supplement books will remain valid at launch. This means:

This approach mirrors how Games Workshop handled previous edition transitions and gives players time to adapt without immediately invalidating their purchases.

What This Means for Competitive Play
