Warhammer 40k 11th Edition Reveals Sweeping List-Building Overhaul for 2026

The sneakiest change in Warhammer 40,000's 11th Edition preview isn't on the box art. It's the moment you decide which Character goes with which unit. Where 10th Edition let you assign Characters to units at the game table, 11th Edition locks those pairings at list-writing, before you've seen your opponent's army. Rob Baer of Spikey Bits called it "the sneaky-biggest Warhammer 40k 11th Edition rules change in the preview," and once you think through what it does to your build decisions, it's hard to disagree.

The full scope of the list-building overhaul came into focus on April 2, drawing on details Games Workshop presented at AdeptiCon 2026 on March 25. The June 2026 launch is confirmed, and the structural changes touch every phase of army construction.

The headline mechanic is Detachment Points. Each detachment carries a cost between 1 and 3 points, weighted by how broadly its rules affect your army: a narrow, unit-focused detachment costs 1; something that buffs your entire force costs 3. A Strike Force game, the standard competitive format at approximately 2,000 points, grants 3 Detachment Points, 4 Enhancement slots, and the familiar unit cap of 3 for non-Battleline and 6 for Battleline. That budget opens two obvious architectures. You can anchor on one 3-point detachment and supplement it with a 1-point pick for a focused, high-impact build. Or you can run three separate 1-point detachments, trading depth for breadth across different unit synergies. Bell of Lost Souls called the Detachment Point limits "kind of a big deal," and structurally it's hard to argue: 10th Edition allowed exactly one detachment per army. 11th Edition opens the door to genuine multi-detachment design, with over 70 new and updated detachments confirmed at launch, including the Iron Warriors' "Warpstrike Champions" highlighted by Frontline Gaming.

Building a Strike Force list under the new system follows a clear sequence. Start by deciding whether your army's core identity demands a 3-point army-wide detachment or whether a pair of focused 1-point picks serves you better. Then allocate your 4 Enhancement slots and check for the Upgrade tag: an Enhancement carrying it can apply to up to three non-Character units as a single slot choice, though each instance still pays its own points cost. Finally, lock your Character assignments. Units can carry one Leader and one Support, but those pairings are fixed at list-submission. An Apothecary hardwired to a Tactical Squad at list-writing cannot shift to a Devastator Squad once you see the mission.

Force Dispositions add another pre-game layer. Each detachment grants Dispositions that interact with your opponent's choices to shape mission parameters, a mechanic with no equivalent in 10th Edition. Frontline Gaming described it as "a clever little shift, because it makes army construction matter before the first die is rolled." Combined with locked Character pairings, the whole system means 11th Edition effectively begins the moment you submit your list.

Before June, the practical questions for any existing collection: do your Characters have clear Leader or Support roles, and do you own enough of each type to cover the pairings you want locked in? Can your current detachment picks fit within 3 Detachment Points without sacrificing the combos that make your army function? And if an Enhancement you rely on gains the Upgrade tag, does spreading it across three units actually improve your build, or does the points overhead price it out entirely?

Games Workshop confirmed current codexes and campaign supplements remain valid in 11th Edition. The architecture around them is being rebuilt from the ground up.
