Warhammer 40,000 (Tenth Edition): Codex – Imperial Agents is an expansion for Warhammer 40,000 (Tenth Edition) released in 2024 for 2 players. Its main mechanics are Variable Player Powers, Dice Rolling, and Measurement Movement.
Imperial Agents emerge from the shadows when heresy threatens to destabilise worlds, cultists seek to summon daemonic abominations, and xenos corruption endangers Humanity's realm. Some are Inquisitors of the Holy Ordos and their motley cadres, but this umbrella term also encompasses terrifying Assassins, swashbuckling Rogue Traders, fanatical priests of the Imperial faith, and other more specialised individuals. Some join more conventional Imperial armies to either further their own ends or lend their resources to an important battle. No matter the cause or nature, Imperial agents are amongst the most secretive and esoteric servants of the Golden Throne. Codex: Imperial Agents delves deeply into the murky origins of these clandestine organisations, offering insight into their methods of war. This also includes the mysterious Deathwatch Chapter of Space Marines, seconded as they are to the Ordo Xenos, and other key units attached to various agencies, including the Sisters of Battle, Grey Knights, Imperial Navy, Adeptus Arbites, and more. You'll find loads of grim and sinister artwork to inspire you, along with beautiful galleries of painted miniatures. This hallowed tome gives you all the rules you'll need for engaging in the shadow war for the heart of the Imperium, whether it's in Combat Patrol, narrative Crusade campaigns, or matched play games of Warhammer 40,000. Inside this 128-page hardback book, you'll find: Background material and lore for the various different types of Imperial Agents, from the Assassin temples, to the Ordos of the Inquisition, and the forces that commonly fight alongside them Evocative artwork and photography that will inspire your own collection and unleash your creativity Full rules for using Imperial Agents in your games, with 26 datasheets for each available unit, including Deathwatch, Assassins, Grey Knights, Sisters of Battle, Imperial Navy, Adeptus Arbites, and more, plus four Detachments A full set of rules for running your own Shadow Operations narrative Crusade campaign, as well as playing fast-paced Combat Patrol skirmishes This book also contains a one-use code to unlock Codex: Imperial Agents content in Warhammer 40,000: The App.
