This multi-part plastic kit contains the components necessary to assemble 5 Grundstok Thunderers professional soldiers and the main fighting force of the Kharadron Overlords. Each is armed with an aethershot rifle with some impressively chunky special weapons available as options - an aetheric fumigator a Grundstok mortar (with an extra bomb for modelling on the base) an aethercannon (so powerful that the duardin carrying it needs a blast shield) and a five-barrelled gun known as the Decksweeper. Their sealed suits of armour are covered in valves pipes and respiratory systems used to make the air palatable to their aether-gold addled lungs.

There are options for a gunnery sergeant and honour bearer - the gunnery sergeant wields a special double-barrelled aethershot rifle can be modelled with a prosthetic leg has 2 differing head options and features a Drillbill: a bizarre mechanical bird who can launch himself at enemies. The honour bearer features a keystone added to his suits
