About this game
Warhammer 40,000: Dawn of War IV is a top-down real-time strategy game set on Kronus, bringing the series back to its strategic roots. Lead Space Marines, Adeptus Mechanicus, Necrons, or Orks across more than 70 campaign missions, with faction-specific campaigns and choices that can change the story and missions available on later playthroughs. Build and reinforce bases, seize requisition points, research upgrades, recruit forces, and deploy units using cover, Sync Kill melee combat, and resource-powered stratagems such as orbital bombardments. Customize units with the Painter tool, play the campaign in co-op, or battle in Skirmish, returning Last Stand, and 1v1, 2v2, or 3v3 multiplayer modes.
