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 a volley of devastating firepower. 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.
