Warhammer 40k Adeptus Mechanicus Ironstrider

Fra games-workshop.com:

With a distinctive two-legged walking tank-shape, the artillery platform known as the Ironstrider Balistarius is a fearsome sight indeed. Gyroscopically balanced, with downlinks providing them with the sum knowledge of their enemies, the deadly accuracy of the Ironstrider Ballistarius would be the stuff of legend, were any survivors ever left to recall it.

As a mobile artillery weapons platform, the Ironstrider Ballistarius can be fitted with one of two armament options: a twin-linked cognis autocannon or a twin-linked cognis lascannon. The split-toed legs can be posed in two different configurations, with suspensors that can be modelled at differing angles, and the entire surface of the machine crawls with sensors, data collection modules and antennae. The gunner has four head options; three hooded and one rebreather.

This multi-part, 80-component plastic kit contains all the parts necessary to build either one Ironstrider Ballistarius or a Sydonian Dragoon, and features a small transfer sheet and a 105x70mm oval base.
