How the gameplay direction is changing
Warhammer Community describes IV as returning to the series’ “mass-battle, base-building roots.” That language signals the direction its developers and publisher are emphasizing. It does not establish exactly how base-building works in the finished game, or prove that III lacked it.

III’s official Steam description instead spotlights collectible elite squads with special abilities, giant war machines, colossal battles and devastating faction abilities. The contrast is one of stated emphasis: IV foregrounds mass battles and base-building, while III’s store copy foregrounds elite units and large battlefield assets. IV remains unreleased, so the two games’ actual feel cannot yet be compared as a played experience.

#1 Best Overall
- The first book of its kind, this Ultimate Guide goes into unparalleled detail on the miniatures and lore of Warhammer 40,000 and is sure to delight long-time fans and newcomers alike.
- Lavishly illustrated with hundreds of beautifully shot photographs of Warhammer 40,000 miniatures that showcase fine details and intricate designs across each faction, from the mighty Space Marines to the ravenous Tyranids, foul Chaos Daemons, deathless Necrons – and more.
- Written by Guy Haley and Gav Thorpe – these prolific Black Library authors who are household names of Warhammer fandom walk you through this world with richly detailed descriptions and insights into the lore.
- Packed with insight into the game’s defining miniatures, Warhammer 40,000: The Ultimate Guide goes deep into the Warhammer 40,000 universe like never before.
The clearest roster changes are the addition of Necrons and Adeptus Mechanicus to IV’s announced lineup, while Eldar are not listed among its four announced launch factions. A larger faction count alone does not establish greater strategic depth, balance or variety in practice.
How do the campaigns differ?
III’s official store page describes a campaign told through alternating missions among its three factions. IV is announced with a different structure: each of its four mechanically distinct factions gets a unique campaign, and all four contribute to one overarching story.
Rank #2

Official Steam news announces more than 70 missions for IV, playable solo or with a friend. The publisher also calls the Kronus conflict the series’ “largest campaign ever,” but does not provide a comparative measurement. The announced mission count is not a measure of campaign hours, and the available descriptions do not establish comparative playtime or quality.

IV’s setting: Kronus
IV’s conflict takes place on Kronus, which the official trailer update identifies as a planet first seen in Dawn of War: Dark Crusade. This gives the sequel a setting connected to an earlier entry in the series.
Rank #3
- Enter the grim but silly Warhammer 40,000 universe with a standalone Munchkin card game where 3-6 players loot, level up, and laugh while battling monsters, grabbing gear, and racing to be the first to reach the top level.
- Choose from iconic factions like Ultramarines, Orks, Necrons, and more, each packed with tongue-in-cheek references that Warhammer fans will recognize while Munchkin fans enjoy new ways to break the rules and backstab friends.

- Designed for 3-6 players ages 12 and up with a 1-2 hour playtime, this card game fits game night groups that enjoy tactical choices, take-that moments, and plenty of table talk as alliances shift from turn to turn.
- Features classic John Kovalic art, trademark Munchkin humor, and easy-to-learn rules, making this Warhammer crossover a playful way to introduce new gamers to Munchkin or add a fresh twist for long-time fans of the series.
What modes and multiplayer features are announced?
Deep Silver lists competitive multiplayer, Last Stand and Skirmish for IV, and says many modes support co-op as well as single-player. The developer’s official Steam news also names Annihilation and Domination as selectable matchmaking modes.
III’s official Steam page lists online PvP. Relic’s 2017 announcements record post-release additions including multiplayer maps, Elite units, skins and custom-game options. These feature lists do not establish IV’s future player population, balance, competitive health or long-term support.

Release date and platform
As of October 4, 2026, Dawn of War IV has not been released. Deep Silver lists December 3, 2026 as its launch date on Steam for Windows PC, with Commander Edition early access beginning November 30. The official Steam news feed records that the launch moved to December 3 from an earlier September target.
Dawn of War III is already available as a PC game on Steam and lists April 27, 2017 as its release date. IV’s date is a planned release date, not confirmation that the game is already playable.
What the comparison can—and cannot—tell you
The announced changes are substantial in scope: a different stated gameplay emphasis, a four-faction roster, four linked faction campaigns and a set of named multiplayer modes. But because IV is still unreleased, those announcements do not establish its final performance, balance, campaign quality or how it compares in actual play with III.
For now, the fair comparison is between official descriptions and plans. A hands-on judgment about which game plays better has to wait until IV is available and has been played.
