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 capable of bearing a varied and devastating armoury. While some Legions valued the Leviathan for its volleys of long-ranged firepower, others took advantage of its fearsome bulk to crush all opposition between brutal claws or armour-sundering drills.

This plastic upgrade kit can be used to equip your Leviathan Siege Dreadnought with deadly melee weapons, replacing or supplementing its arm-mounted heavy munitions. The kit includes the components to build two mechanical fists for a Leviathan Dreadnought. Each fist is armed with a built-in meltagun, and can be assembled as either a crushing siege claw or grinding siege drill, with individually posable digits. The kit also provides two sets of alternate power cables, each suited to different arm poses.
