I played two of Dawn of War 4's four campaigns, and the orks and Adeptus Mechanicus each bring something different

PC Gamer's Fraser Brown spent a couple of weeks playing two of Warhammer 40,000: Dawn of War 4's four campaigns, the orks and the Adeptus Mechanicus, plus the two-mission Astra Militarum prologue. The ork campaign centres on a rivalry with invading orks over Kronos, including a race mission to destroy the Adeptus Mechanicus base first, after which players pick a side for the rest of the campaign. The Adeptus Mechanicus campaign is slower and built around the Noosphere Network, and cover returns with ork-built barricades and 360-degree Emanatus Field Generators.
