Horus Heresy Mechanicum Battle Group

The core of the box is a cohort of six Thallax, armed with vicious lightning guns and a variety of special weapon options. They’re surprisingly nimble, pairing their durable chassis with a highly responsive Inculabulan jet pack.

Despite looking decidedly robotic, the Thallax are actually cyborgs. Their major organs, nervous system, and cerebrum are all encased within armour-bodies known as the Lorica Thallax – an agonising process that strips away pain centres and emotions, but leaves a measure of independent human thought not found in automata.Behind these Ordo Reductor shock troops is a shambling covenant of 20 Adsecularis Tech-thralls. These augmented once-humans are often the result of punishments for a Tech-Priest’s menial labourers – unlike servitors, their personalities and thoughts are not removed entirely, merely overridden by implants – but when war looms, they are refitted as expendable troops in hasty musters.

Although they lack much in the way of skill or advanced equipment, these ghoulish puppet-conscripts are utterly indefatigable and often overwhelm far superior troops through mindless determination and weight of numbers

A Triaros Armoured Conveyor is a beast of a transport that can ferry either of your two core units around, with a huge capacity of 22 – so even your Thallax, with their Bulky (2) special rule, can fit inside. The armoured prow protects the front from all but the worst anti-tank weapons, and doubles up as a destructive shock ram for smashing straight into targets too big for your mounted volkite and bolt weapons. Factor in the built-in flare shield, and your cargo will be making it to the front lines intact.

Finally, a pair of lumbering Castellax Battle-automata bring up the rear, offering plenty of heavyweight ranged and close combat power in a highly resistant package. Each one of these robust robots has a range of weapons to choose from – including power blades or shock chargers with built-in bolters or flamers, plus a shoulder-mounted bolt cannon, multi-melta, or sinister darklight cannon. They’re a mainstay of the Legio Cybernetica, with particularly aggressive machine spirits that lend them well to blunt front-line attacks and shock assaults.
