|The book itself|
|The dropsite Massacre|
From what I can tell there's going to be a huge amount of new units in this book. A smattering of generic add-ons to the Legion list from book 1, a few more Mechanicum units but still not a full army, and a lot of legion-specific units. Here's what I've got so far -
Generic - Sicaran Battle Tank, Javelin Attack Speeder, Glaive, Fire Raptor (although it could be Salamanders)
Mechanicum - Magos Dominus, Castellax Battle-Automata.
Specific - Erebus, Kor Phaeron, Ferrus Manus, Kakophoni Noise Marines, Phoenix Guard, a new unnamed World Eaters unit.
