Adeptus Titanicus: The Horus Heresy is a based around combat between Battle Titans, you are the Princeps Seniores of a Titan maniple, taking control of a number of war engines and interfacing with your models via unique Command Terminals. The game is designed to make you feel like the commander, issuing orders and directing your God-Machines to grind down the enemy, popping void shields and damaging their systems before making a definitive killing blow. The game uses a system of alternating activations across distinct Movement, Combat, Damage Control and Stratagem phases.[3] Three distinct ways to play are available :

  • Open play has few restrictions, allowing you to craft your own missions.[3]
  • Narrative play is story driven, using scenarios from the greatest battles of the Horus Heresy series[3]
  • matched play is designed for competitive games, utilising victory points and tactical objectives for balanced play.[3]

Specific rules are included for each Titan Legions, each with unique traits and wargear.[3]
