The Legiones Astartes deploy super-heavy assets when the need is great – massive battle tanks with weapons so powerful they can obliterate other war machines, and threaten even enemy Titans. In some extreme cases, both sides utilise these tanks, unleashing devastating ordnance upon each other until the battlefield is littered with smouldering hulks.

This gaming supplement for Warhammer: The Horus Heresy details the origins, weaponry, and usage of the super-heavy vehicles of the Legiones Astartes from their inception into the Age of Darkness. Additional rules allow you to play massive armoured assaults, including asymmetrical missions and multiplayer battles.

This 48-page softcover supplement contains:
– The Fist of the Legions: Detailed background on some of the largest armoured assets available to the Legiones Astartes.
– Mission Rules: The information you'll need to play the Vaults of Thrasis Legendary Mission, along with three Leviathan missions featuring asymmetrical objectives.
– Additional Profiles and Liber Addenda: New Battlefield Assets, a Unit Profile for the Whirlwind Missile Tank, and rules for Legion Decurion upgrades for the Fellblade Super-heavy Battle Tank and the Falchion Super-heavy Tank Destroyer.

You will need a copy of the Warhammer: The Horus Heresy – Age of Darkness Rulebook and either Liber Hereticus: Traitor Legiones Astartes Army Book or Liber Astartes: Loyalist Legiones Astartes Army Book to make full use of this supplement.
