The Martian robots are finally here. Come see the new Kastelan robots and Datasmith up close.

Love it or hate it, the new release does bear a strange resemblance to the Baymax character. It’s clear with this guys though, the datasmith is the once in charge!

Theses new Kastelan Robots are kicking off the start of a Cult Mechanicus release that looks bridge the weaknesses in the Skitarii codex.

Their box set contains all the parts you need to make two of the new Kastelans, and their Datasmith ‘handler’ .

A huge, ancient robot built ten thousand years ago, the Kastelan Robot is a perfect example of the Adeptus Mechanicus’ repurposing of technology. Nearly unstoppable, their only flaw is that of any mere machine; they will follow instructions to the letter, even if this results in their own demise. A specialist Tech-Priest – the Cybernetica Datasmith – must constantly update and reprogram the Kastelan via order dataslates, lest this enormous, clanking robot simply stride blindly into a nearby chasm. Make no mistake, however; when his controls are set to destroy, the Kastelan will destroy.

This ninety-five component multi-part plastic kit contains everything you need to make two Kastelan Robots and one Cybernetica Datasmith. The Kastelan Robots are armed to where their teeth would be, if they had teeth – options include two sets of power fists, two sets of twin-linked phosphor blasters and a choice of carapace-mounted weaponry (incendine combustor or yet another phosphor blaster – two of each are supplied). The Cybernetica Datasmith is armed with a gamma pistol, dataspike and a servo arm assembly featuring a rivet gun. A prehensile socket drill allows him to reprogram the Kastelan Robots on-the-fly. He also features a choice of two heads.

kastelan instuctions



  • Interchangeable arm and shoulder mounted weapons (Kastelans)
  • Removable Chestplates (Kastelans)
  • ‘Pose-able’ legs (Kastelans)
  • Datasmith can be used for other roles like tech priests, etc…
  • Two heads for Datasmith model!
  • Contemptor dreadnought convertible?


  • Robot Heads will be hard to convert
  • ‘Clampack’ design limits Datasmith’s conversion potential
  • Rules not fully revealed yet (wave one)

If you’re looking for the full 40k rules to for the new models, you can pick up White Dwarf #67 for most of them or wait for the impending Cult Mechanicus codex to hit shelves in a few weeks. They also come with abbreviated rules in the instructions as well!


The new three model box set retails for $69 US and honestly does’t seem like a bad deal for two large models and one character.

It feels good to see more ‘inspired’ models from the 1990’s!
