Details.

Standing at three times the height of a human, clad in heavy armour, and equipped with durable atomantic shields, the Castellax Battle-automata are terrifying machines of war. 

This maniple box contains two Castellax, which can be built with brutal shock chargers or savage power blade arrays, and which have a choice of in-built bolters or flamers. Their sturdy frames allow them to carry shoulder-mounted mauler bolt cannons into battle, and the box also contains one darkfire cannon and one multi-melta for more specialised loadouts. You also get a Mechanicum Constructs transfer sheet comprising 558 decals.
