I was just told that there is a new Giant Robot for Cult Mechanicus in the Heavy Support slot
You get 2 giant robots and one Datasmith as a squad. The robots stand twice the ht of a space marine and are MCs. If I remember correctly you can add additional robots, it was 2 or 3. The Datasmith is a character that controls them.
