Heroes of Might & Magic III: Horn of the Abyss

The Forge Castle, as depicted in these screenshots, wouldn't fit well among the other "heroic" factions. However, there are ongoing discussions and development (without official involvement from the HotA team, but with the participation of some members and, let's say, under general supervision) – currently at the concept, idea, and initial graphic development stage – for a city called Factory. This is a much more reasonable faction, closer in atmosphere and style to the original castles of Heroes III, but still retaining the core idea of a cyber/techno-city.
If the Factory is graphically ready within the next year or so, there is a possibility of integrating it into later versions of HotA.
