Doom of Molech focuses on the battle for the Knight World of Molech during the Horus Heresy. A key conflict, this saw the entirety of House Devine betray their oaths and turn to the Warmaster’s side, leading to a massacre of Loyalist forces on the embattled world. It was also the site of some of the most vicious Titan and Knight fighting in the entire Heresy.
With this new expansion, you’ll be able to recreate these battles using six new narrative missions that let you fight key moments from the war. There’s also a new matched play mission that pits your forces against the mighty beasts that roam the world, for a very different kind of challenge. New battlefield conditions and Stratagems also give a host of new options for every Adeptus Titanicus player.
Knights are very much the focus, with a plethora of rules for using entire armies from the Knight Households in open, narrative and matched play, along with comprehensive additions to the Adeptus Titanicus core rules to make using full Knightly armies easier.
