Dawn of War 4 Adeptus Mechanicus will be one of four playable factions in the upcoming strategy game, but the choice was not automatic. Creative director Jan Theysen said the team at King Art explored several other options before settling on the tech-priest faction for the final slot.
The game will feature separate campaigns for the Space Marines, Orks, Necrons, and Adeptus Mechanicus. Theysen explained that the faction roster was the first major decision because the Warhammer universe revolves around its varied and distinctive armies.
Building on Dawn of War's Legacy

Theysen said the studio aimed to create a modern take on the original Dawn of War. The Orks were an obvious inclusion, not least because the character Gorgutz is closely associated with the series. The Necrons were also added, partly because they had been promised for Dawn of War 3 but never appeared. The team saw their inclusion as a fitting way to finally deliver on that expectation.
With Space Marines filling the third slot, one position remained. The developers wanted a faction that had never been playable in a Dawn of War game before, so they began reviewing the possibilities.
Why Adeptus Mechanicus Won Out
Among the candidates were the Death Guard and the Leagues of Votann. Theysen said the team ultimately felt Adeptus Mechanicus was the most significant faction never to have appeared in the series, both in terms of lore and size. He described it as the biggest and most important faction that had been left out.
Gameplay also played a decisive role. Theysen noted that the Death Guard is a relatively slow army, and with Necrons and Space Marines already offering durable, tanky options, another similar force would have felt redundant. Adeptus Mechanicus, by contrast, brings speed, strong ranged firepower, and a distinct identity that sets it apart from the other three factions.
That contrast convinced the team to go with Adeptus Mechanicus. Theysen said the faction’s fast-paced, gun-line style felt very different from everything else in the game, making it the right fit for the fourth and final slot.
Other Details Ahead of Launch
Dawn of War 4 is scheduled for release on December 3. Theysen also mentioned the game’s advanced animation system, called Combat Director, which initially seemed like an impossible technical challenge.
