Dawn of War 4 Chose Adeptus Mechanicus Over Death Guard for Its Fourth Faction
Dawn of War 4 creative director Jan Theysen says the team weighed Death Guard before choosing Adeptus Mechanicus as the game's fourth faction campaign.
According to TechRadar, Dawn of War 4 creative director Jan Theysen has said that the studio King Art looked at adding more playable factions beyond the ones that made the final lineup. Among the options, the team experimented with Death Guard, but Theysen said that faction felt too similar to others already in the game's plans.
Instead, the studio settled on Adeptus Mechanicus as the fourth faction. TechRadar reports that Theysen described it as the most important faction in the Warhammer 40,000 lore that has never before been part of a Dawn of War game, and he framed the decision around the lore rather than gameplay alone.
The game will feature four separate faction campaigns, covering the Space Marines, Orks, Necrons and Adeptus Mechanicus, TechRadar says. The report is based on a creative director's comments and does not describe how those campaigns will play, when the game will launch or on which platforms it will appear, and those details were not covered in the reporting.
The comments offer a window into how the developers approached the franchise's roster. Choosing between two candidates that both have strong fan appeal means balancing thematic weight against how distinct each faction will feel in play.
Background
Warhammer 40,000 is a tabletop wargame published by Games Workshop, set in a grim far future where humanity's interstellar empire fights wars on many fronts. Its universe is known for a dense roster of factions, each with its own history, aesthetics and rules, and that breadth has made it a popular source for video games.
The Dawn of War series is a real-time strategy franchise that has been part of the Warhammer 40,000 video game lineage since the original release in 2004, developed by Relic Entertainment. Earlier entries have drawn on a range of Imperial, alien and Chaos forces, and the series is widely remembered for large battles, base building and faction-specific unit design.
Adeptus Mechanicus is the Imperium's priesthood devoted to technology and the worship of machines, known for its unusual relics, cybernetic enhancements and rigid ritual. Death Guard is a Chaos faction associated with plague and decay, and it is among the most recognizable of the Chaos Space Marine forces in tabletop and digital adaptations.
Real-time strategy games depend on factions that feel mechanically different from one another, not just visually distinct. Developers often consider factions in terms of resource systems, unit roles and how players approach a battle, which means a faction can be rich in lore but still difficult to differentiate in practice. Campaign structure also matters, since separate faction campaigns can reveal a faction's identity through narrative as well as gameplay.
Why it matters
Fan communities closely follow which factions appear in a new game, and roster decisions often shape early expectations. Choosing a faction that has been important in the lore but absent from previous entries signals that the developers are interested in both expanding the franchise and rewarding long-time readers of the setting.
The reasoning TechRadar reports also highlights a common tension in game design. A faction that closely resembles an existing one can dilute the variety players expect, while a faction with a distinct identity may need more work to feel complete. How the team resolves that trade-off will influence whether the four campaigns feel like four different games or variations on a shared template.
For King Art, the decision carries reputational weight. A strong showing in a major franchise can build trust with both licensors and players, and the way the studio handles faction identity may signal its approach to the wider project.
The story is also a reminder that many design choices happen out of public view. Comments from a creative director offer a rare look at the trade-offs behind a final lineup, even when the full game has not yet shown its mechanics.
What to watch
The most important open question is how the Adeptus Mechanicus campaign will play. Gameplay footage, unit descriptions and any official breakdown of the four campaigns will show whether the faction's lore translates into a distinct experience on the battlefield.
Fans will also be watching whether Death Guard or other factions return in later updates or expansions. Nothing in the reporting suggests a plan for that, so any such move would be speculation until the developers confirm it.
Release timing, platforms and pricing are not covered in the reporting and remain unannounced. Official announcements in those areas would clarify how the game fits into the franchise's future.
Viewpoints
Commentary from our columns: three angles on this story.
The Skeptic open questions and weak points
It is easy to nod along when a creative director explains a design choice in lore terms, but the explanation raises questions worth asking. Calling a faction the most important one never to appear in a Dawn of War game is a claim about significance, and significance does not automatically produce a good campaign. The real test is whether Adeptus Mechanicus plays differently enough from the Space Marines and Necrons to justify its place. Death Guard was dropped because it seemed too similar to existing options, which means the team was already worried about overlap. Fans should keep that concern in view. Until gameplay shows how the four campaigns differ, the lore argument is a reason to be interested, not proof that the design works. The skeptical question is simple: what does this faction do that the others cannot?
The Builder the engineer's view
From an engineering standpoint, a faction choice is a set of systems before it is a story. Every faction needs unit sets, resource loops, command abilities and an AI that uses them sensibly. Adeptus Mechanicus invites interesting mechanics, such as tech-driven upgrades or machine-spirit support, but those ideas only work if the simulation supports them cleanly. The decision to weigh Death Guard against other candidates suggests the team was testing how a faction would sit against its neighbors in practice, not just on a concept sheet. That is good practice. The team now has to prove that a lore-first pick can hold up under balance testing and multiplayer pressure. Watch for how quickly the faction's core loop becomes readable to a new player, because that is where a good concept either becomes a fun system or stalls.
The Optimist the hopeful reading
There is something encouraging about a studio that thought hard about its roster and picked the option that felt most meaningful to the setting. Choosing Adeptus Mechanicus because it is central to the lore and has never had its moment in a Dawn of War game gives long-time fans a reason to feel seen. It also shows a willingness to give a sprawling universe a fresh corner rather than repeating familiar choices. Four separate faction campaigns is an ambitious structure, and it offers room for each army to speak in its own voice. Even without gameplay details yet, the intent reads as care for the source material. If the team delivers on that intent, this could be a moment when a franchise returns with new identities and a stronger sense of why each faction matters.
