Campaign

The campaign in Total War: Warhammer 40,000 operates at a galactic scale and is structured as a hybrid between a traditional turn-based campaign and a meta-progression layer that ties multiple campaigns together. Players expand their control region by region on individual planets while fleets move between worlds through zones of concentrated conflict called Crusade Theatres. The campaign was discussed in detail during the Show and Tell livestream on 30 April 2026 and the earlier developer roundtable, with further detail at the June 2026 PC Gaming Show.

The Galactic Map

The galaxy view functions as a hybrid between a campaign selection menu and a meta-progression overview. Players do not move armies directly across the entire galaxy on a single turn timeline. Instead, the galaxy view offers several campaigns to take part in, each set within a defined region of contested space. Completing campaigns produces lasting changes that influence which campaigns and battles become available next, and how powerful or prepared the player's faction will be when entering the next theatre.

Crusade Theatres

Each individual campaign takes place within a Crusade Theatre: an area of the galaxy seen as a hot point for conflict where multiple factions are fighting one another. Within a Crusade Theatre fleets move between planets along established star lanes, fight battles for individual worlds, and project power into adjacent systems. According to the framing in the developer roundtable, each completed campaign feeds into a higher layer that gradually shifts across the sector, and eventually across the galaxy as a whole, so individual victories carry weight beyond the campaign in which they were won.

Branching Campaign Paths

The June 2026 reveal confirmed that a campaign's story has branching paths. The choices the player makes and the territories they conquer steer which path the campaign follows, so a campaign is not a fixed sequence of battles. Creative Assembly also confirmed story-driven campaigns that teach the game's mechanics and the setting to newcomers, so players new to Total War or to Warhammer 40,000 have a guided way in.

Territory and Faction Bonuses

Controlling territory provides gameplay benefits that differ by faction. The reveal gave two confirmed examples: Orks can build Stompa war engines faster when they hold territory that yields Scrap, while the Astra Militarum gain a boost to tank production when they control a Plant on a civilised world. This ties each faction's economy and reinforcement strength to the kind of ground it captures.

Campaign Layers

Lead designer Simon Mann has described the campaign as operating on several nested layers. At the lowest layer the player fights real-time battles for individual regions on a planet. Capturing a region (for example a hive city) hands its resources and infrastructure to the player and creates a staging point for the next region. Capturing all the regions on a planet hands the planet itself, which in turn opens up access to the rest of that system. Star systems are connected by star lanes within a Crusade Theatre, and Crusade Theatres themselves are arranged across the galaxy view at the top level.

Fleets

Fleets serve three confirmed roles. They transport armies between planets, drop forces directly into battle from orbit, and call in off-map bombardments both in the campaign and during real-time battles. Fleet upgrades have been described as one element of the war economy. Fleet-versus-fleet space combat has not been confirmed for launch.

Campaign Lengths and Modes

Three campaign formats have been confirmed. Full campaigns are the closest analogue to traditional Total War campaigns. Short campaigns offer a more contained experience. Single decisive battles let players engage only in the real-time battle layer without a campaign context. Single-player, online player-versus-player, and co-operative modes are all confirmed.

Planets and World Types

Each star system contains several planets that vary considerably in character. Confirmed civilisation types referenced in press materials include hive worlds (densely populated industrial superplanets), agri worlds (vast agricultural producers), mining worlds, fortress worlds, and frontier worlds (sparsely settled outposts). Each planet has its own type of civilisation regardless of its biome. The hive world shown in the Show and Tell livestream featured six mega cities visible at full 3D resolution from the planet view.

Planet Biomes

Four planet biomes have been confirmed. Each influences the visual character of battles fought on those worlds, and the development team has described a texture-paint system that lets the same underlying battle map shift its surface treatment to match a different biome.

Battle Maps

Battle maps within a planet vary by region rather than being identical reskins. The same underlying map can appear with different biome textures depending on which planet hosts it, and the same region can be fought across multiple orientations: north to south or east to west, and as either an attack or a defence battle. Confirmed map types include dense hive cities, hive outskirts, arid wastelands, and ice plains.

Two specific maps have been shown. The Upper Hive Plateau, from the Show and Tell, illustrates the dense-urban end of the spectrum with multi-storey buildings and anti-aircraft fire visible in the background. The Shattered Expressway, shown at the June 2026 PC Gaming Show, is a war-torn stretch of a polluted Imperial world on Armageddon, where the Astra Militarum and Orks battle was demonstrated.

Planetary Destruction

Exterminatus, the apocalyptic destruction of an entire planet, is confirmed as a campaign action. The development team has characterised it as a costly option rather than a routine tool: it permanently destroys the planet, and players are unlikely to be able to deploy it freely throughout a campaign.
