Heroes of Might & Magic III: Horn of the Abyss

Well, there won't be any compatibility with SoD.

Why? SoD maps and Campaigns will work perfectly in their original form. At the same time, any external changes can be disabled, and ideally, you will get the most authentic classic Shadow of Death version 3.2.

Are there any fundamental issues, or perhaps some dislike for ERM? Is there anything that ERM doesn't offer?
Why did you decide to use your own language? Fans will have a hard time) On that same forum, someone lamented that they spent 3 months learning ERM, and now there's a new language.

Well, you seem to have misunderstood – ERM is not going to be canceled.

Or is it related to the fact that zvs is supposedly ending support for WoG and ERM after the release of version 3.59?

We are not talking about ZVS, but rather about the independence of the Horn of the Abyss project from any other projects, even from WoG, which is beloved by all of us – the father of all fan mods and add-ons for Heroes 3.

right now, there is a great need for interesting and original ideas regarding new objects on the map. If anyone has any thoughts on this, please write, and maybe your idea will be included in the first version.
