Warhammer: The Horus Heresy Journal Tactica - The Isstvan V Dropsite Massacre Part One 48-page Softcover Supplement

The Horus Heresy Journal Tactica: The Isstvan V Dropsite Massacre Part One is a narrative gaming supplement designed for the Warhammer: The Horus Heresy tabletop wargame system. This publication focuses specifically on the pivotal Isstvan V conflict, where the galactic civil war known as the Horus Heresy erupted into open warfare. It provides players with the background, rules, and scenarios needed to recreate the infamous Dropsite Massacre, allowing them to command either the treacherous Traitor Legions as they launch their surprise assault or the beleaguered Loyalists as they desperately rally a defence. The 48-page softcover book contains detailed background lore chronicling the events from the first reports of the Warmaster's betrayal. It introduces new gameplay elements, including unit profiles for the Master of Descent, Augur Command and Control Squad, and the Hyperios Missile Tank. Additional rules such as the Interdiction Cadre Prime Advantage and Battlefield Assets mechanics add strategic depth to games. The centrepiece is the 'First Wave' legendary scenario, which enables players to recreate the initial, shocking assault on the black sands of the Urgall Depression. This supplement is best suited for experienced Horus Heresy players looking to expand their narrative and matched play options with a deep dive into one of the setting's most critical battles. To use the content, players will require the core Warhammer: The Horus Heresy – Age of Darkness Rulebook and either the Traitor or Loyalist Legiones Astartes army book. It serves as a specialised expansion that enforces the thematic and tactical experience of this specific, galaxy-altering event.
