This Imperial Fists Leviathan Siege Dreadnought was part of The Fall Of Outpost Sigma-12 diorama at Warhammer World.
Heavily-armed and impressively armoured, the Leviathan Siege Dreadnought is an alternative development of the highly successful Contemptor design. These rare and mighty engines are prized by Astartes commanders, recognised as savagely powerful siege and hunter-killer units that can crush any opposition with an unstoppable wrecking charge. Yet such overwhelming strength comes at a cost – a Leviathan’s systems place an onerous and ultimately lethal strain upon its occupant, the entombed incumbent burning brightly but only briefly in their second life
The ranged weapons of the Leviathan pattern Siege Dreadnought were designed to be used at closer range than those carried by most classes of dreadnought. The Leviathan Grav-flux Bombard creates a spiralling vortex of gravitation-torsion force. It is a fortress-breaching weapon which can reduce the toughest armour to twisted scrap and crush anything living beyond recognition.
