The developers decided to go all out. The holiday is coming, and all the undead are gathering together in one video. All the units of Necropolis and 11 heroes. Not all the heroes, though; at least, Natalida and Tanta are missing. And there were rumors about Galthran.
So, the army composition is as follows:
1) Skeletons with a ranged attack option
2) Ghosts with the legendary ability from the second and first parts (but it doesn't work as powerfully; it's vampirism with the ability to exceed the initial number of ghosts, and after the battle, new ghosts will rest)
3) Dogs
4) Grave robbers
5) Liches
6) Death Knights
7) Vampires with a ranged attack option. Yes, vampires are the strongest unit in the faction. Quite deservedly, from a lore perspective... and considering their abilities.
Oh yes, there were bone dragons in the screenshots. Probably, this is a tier 7 neutral creature.
P.S. They've already made the damage effects instead of blood, but unfortunately, they didn't make it into this video. The music is a placeholder. Ubisoft doesn't seem to have given Anfrozen anything yet, and he's the one who makes the music. And I think this reveal can be put at the top of the thread.
