Heroes 6 - Discussion

each faction will have its own catapult, which will differ in appearance, and will also have a second special ability, which is unique to each faction.

So, Ment, your idea about fireballs for Inferno and plague infection for Necropolis doesn't seem absurd.

Will there be new combat machines during battles?

No. Only catapults, which I mentioned earlier. Faction catapults.

From this, we can understand that we can forget about tents, wagons, and ballistae. A return to Heroes 4, so will we be destroying walls/gates again? By the way, I posted the full interview in "news", and in the Haven info, I uploaded art of the Archangel Michael...;)
And one more thing On Thursday, they should announce the 4th faction. Finally, I was already starting to think they had forgotten about it.
