Details.

Great swathes of Mars seceded from Imperial rule during the Horus Heresy, and the tireless deluge of machines and weapons pouring from its factories posed a mounting threat to the throneworld as the Warmaster drew ever closer. Loyalist forces attempted to wrest control of the planet on numerous occasions, even as the Tech-priests squabbled among themselves, and these events provide the backdrop for the next supplement for Warhammer: The Horus Heresy, Campaigns of The Age of Darkness: The Martian Civil War.

This 168-page hardback features a selection of background information spanning the length of this unique conflict, and rules for bringing it to life on your tabletop. There are new core missions, apex missions, relic hunt missions, an Onslaught campaign to use them in, plus additional units and Techno-heresy rules to determine the fate of the Red Planet yourself, alongside additional content from previously published Exemplary Battles in the Age of Darkness. This will be available to pre-order next week in hardback and ePub formats.
