About Warhammer 40,000: Dawn of War III

Warhammer 40,000: Dawn of War III pits three factions—Space Marines, Orks, and Eldar—against each other on the volatile world of Acheron. A catastrophic weapon forces each commander to fight for survival, with no clear heroes or villains. The game expands the series with towering war machines, massive armies, and volcanic battlefields, while letting players build a single, customizable army that progresses through both campaign and multiplayer. Online play adds competitive maps and the chance to forge or betray alliances, supported by Steam features such as achievements and a level editor.

01 / THE GUIDE

Three‑Faction Campaign

The single‑player story alternates missions between the Space Marine commander Gabriel Angelos, the Ork warlord Gorgutz, and the Eldar seer Macha. Each side’s unique combat advantages become clear as players experience their distinct units and tactics. The narrative emphasizes a universe where war is the only constant, with no heroes or villains. Understanding each faction’s strengths is key to succeeding in the alternating mission structure.

  • Focus on learning one faction’s units before switching to another.
  • Observe how each mission’s objectives favor the current faction’s abilities.

02 / THE GUIDE

Giants and War Machines

Players can command colossal units such as the Imperial Knight for Space Marines, the Gorkanaut for Orks, and the Wraithknight for Eldar. These towering war machines can tip the balance of battle when deployed. Their presence adds a new scale to the already epic clashes that the series is known for, allowing players to dominate volcanic terrain or orbital Star Forts.

  • Deploy a giant unit when you need a decisive power shift.
  • Protect your titan with supporting squads to maximize its impact.

03 / THE GUIDE

Collectible Elite Squads

Each faction offers powerful elite squads that bring special abilities and bonuses. These units are collectible and can be unlocked as the player progresses. Deploying elites adds strategic depth, enabling new attacking strategies and helping to conquer opponents in both campaign and multiplayer matches.

  • Mix elite squads with regular units for balanced forces.
  • Upgrade elites early to gain their special abilities sooner.

04 / THE GUIDE

Destructive Super‑Abilities

Each faction possesses a signature super‑ability: Orbital Bombardment for Space Marines, Eldritch Storm for Eldar, and Rokks for Orks. These abilities cause massive damage and can turn the tide of a battle when timed correctly. Using them strategically is essential for overcoming well‑defended positions.

  • Save super‑abilities for moments when enemy forces are clustered.
  • Combine super‑abilities with elite squads for maximum effect.

05 / THE GUIDE

Online Multiplayer and Community

The game features online PvP where players can join alliances or betray former friends on chaotic maps. Multiplayer matches use the same customizable army system as the campaign, allowing progression across battles. Steam integration provides achievements, trading cards, a workshop, and cloud saves.

  • Experiment with different army builds in casual matches before ranked play.
  • Use the Steam Workshop to try community‑made maps and balance tweaks.
