Adeptus Mechanicus Onager Dunecrawler
A light walking tank, the Onager Dunecrawler features four crab-like legs with optional armour plating. The armoured cabin and reactor are complemented by a huge variety of modelling options, with searchlights, smoke launchers, cognis manipulators and mindscanner probes; and the cupola can be modelled closed or open, featuring a Princeps wielding a heavy stubber. You get a massive amount of configuration and customisation available even before applying weaponry.
On the subject of weaponry, included in the box are four variants: an eradication beamer, twin phosphor blasters with sensors, a neutron laser featuring a coaxial cognis heavy stubber or an Icarus array - an awesome anti-air assault package comprising twin autocannons, a gatling flak launcher, an armour-piercing missile launcher and a radar dish.
