The Cult of Mechanicus... are like the Empire-sanctioned version of the Borg when you read about them. They take biological forms and remove all that "humanity" nonsense and instead replace it with cold, calculating, robot-stuff. They graft on all sorts of weapon mounts and tool bits and will trade out things like "legs" with tank treads. They have a fanatical devotion to machinery and will simply scour worlds clean, looking for resources in order to fuel their foundries and forges. So yeah... Borg.
Now, I'm sure there's a bunch of Trekkies out there that'll tell me how wrong I am in that analogy. And that's fine. I just call it as I see it.
Anyway, along with the codex (both varieties) and a new transfer sheet, there's some new models to check out. There's the box set that lets you either create the Corpuscarii or Fulgurite Electro-Priests, as well as the pack that gives you the "guy in charge" in the form of the Adeptus Mechanicus Tech-Priest Dominus.
