Leaked Images Are Out- Cult Mechanicus Codex
The leaks are out for the Cult Mechanicus codex. Most of them are in German, and there are also some in Spanish now. (technically I should be able to speak both those languages.... but I cant). The leaks reveal the Cult Mechanicus Detachment, Formations, Relics, Wargear, and Canticles. Definitely worth taking a look at, and hopefully someone can translate some of them.
Here are some links to where you can find them.
