Games Workshop are taking pre-orders for Mechanicum reinforcements that will soon be making their way to the tabletop for Warhammer: The Horus Heresy. New 28mm characters, troops and big, clanking robots are coming to support Tech-priests as they squabble amongst themselves during a galactic civil war.

The Martian Civil War leads the way with lots of in-depth background information covering the conflict. You will also find new core missions, apex missions and relic hunt missions alongside an onslaught campaign to play with them. There will also be additional unit rules and Techno-heresy rules (ooooh). The Mechanicum are fracturing like the Imperium and the fate of Mars is in your hands.

Taking up the mantle of either a Loyalist or a Traitor, you have a new miniature for the Archmagos Prime.

Archmagos Prime // Warhammer: The Horus Heresy

These are high-ranking commanders amongst the Mechanicum and have transformed their bodies to transcend the shackles of mortal flesh. You could either paint your Archmagos Prime as a loyal follower of doctrine or perhaps an experimental scientist and engineer who has tampered with the offerings that the forces of Chaos have to offer.

Watching over your Archmagos Prime, you can have a unit of Thallax Cohort.

The Thallax Cohort can make a solid core for your Mechanicum force. They are solid shock troopers and can be armed with lightning guns as well as phased plasma-fusils, photon thrusters and multi-meltas. There are also loads of head designs for you to customise your squad as well which is handy!

You can also go a little bigger with the Castellax Battle-automata Maniple.

Castellax Battle-automata Maniple // Warhammer: The Horus Heresy

These are more terrifying machines of war and you get two of them in a set. They can be armed with loads of awesome melee weapons but also a bunch of good ranged weapons too. Darkfire cannon? Check! You can specialise the Castellax Battle-automata Maniple to suit your style of play.

If you'd like to go big with your clanking automatons then you've also got the Thanatar Cavas Siege-automata.

Thanatar Cavas Siege-automata // Warhammer: The Horus Heresy

These are some of the largest automata that the Mechanicum can deploy. They are hulks and come armed with some serious firepower in the form of the hellex pattern plasma mortar. They are also armed with shock chargers and twin-linked mauler bolt cannons. Why would you not have one of these in your army?

Not all of your Mechanicum army is going to be made up of big clanking robots. You'll need some fodder as well and that's where the Tech-thralls Covenant come in.

Tech-thralls Covenant // Warhammer: The Horus Heresy

These shambling labourers and Tech-thralls have been dragged from the factories of Mars and refitted with weapons that turn them into cannon fodder. March these troops forward into enemy gunfire and waste your opponent's time as the rest of your force moves into position. They will keep firing even as they take grievous wounds. You might even present your enemy with too many targets and you could overwhelm your foes!

Last but not least, there is also the release of the Triaros Armoured Conveyor.

Triaros Armoured Conveyor // Warhammer: The Horus Heresy

A solid transport option for the Mechanicum that comes clad in heavy armour. It can carry twenty-two miniatures into the heart of battle and comes armed with two volkite calivers, a twin-linked mauler bolt cannon, and has options for two hunter-killer missiles.

All of these miniatures have been freed from previous boxed sets and can now be snapped up individually. They are also all plastic for the first time which is awesome. You can build some great armies now and slot these into armies of Warhammer 40,000 as well with a bit of kitbashing!

What do you think of these Mechanicum miniatures?
