This plastic upgrade kit provides an extra set of ranged weapons for your Contemptor Dreadnought, allowing you to specialise its loadout with a pair of identical arm-mounted ranged weapons. The kit includes the components to build four different heavy weapons – a conversion beam cannon, Gravis plasma cannon, Kheres assault cannon, and volkite dual-culverin – each of which can be mounted on either of your Contemptor's arms. It also contains an additional melee fist, which can be built as either a Gravis power fist or Gravis chain fist, and sports your choice of in-built weapon – a combi-bolter, graviton gun, heavy flamer, meltagun, or plasma blaster. The kit also provides a number of extra components – a helical targeting array, a spare chainfist blade, three chest plates, an alternate head, a choice of power fist digits, and accessories representing scrollwork or decorative shields.

This upgrade kit comprises 57 plastic components and is designed to be assembled with the Contemptor Dreadnought set, which is sold separately. These components are supplied unpainted and require assembly.
