Due to its origin in the lost knowledge of millennia, the Onager Dunecrawler is based on the Mars Universal Land Engine, inspired by malevolent beasts. The Onager Dunecrawler is filled with advanced, powerful weapons capable of turning worlds into wasteland. A light tank for walking, it features four crab-like legs with optional armor plating.

The armored cockpit and reactor are complemented by a variety of modeling options, such as:

• Spotlights
• Smoke launchers
• Cognis operators
• Mind-sensing detectors

The turret can be configured either closed or open, with a Princeps holding a heavy staff. There is a vast amount of configurations and customizations available, even before weaponry is applied. The box includes four weapon variants:

• Exterminator eradicator
• Two phosphor launchers with sensors
• Neutron laser with coaxial cognis heavy stubber
• Icarus array with two autocannons, a gatling flak launcher, an armor-piercing missile launcher, and a radar dish

The multi-part plastic kit contains 119 components, builds one Onager Dunecrawler, as well as a small transfer sheet for Adeptus Mechanicus and a 130 mm round base.
