Heroes of Might and Magic III: Horn of the Abyss also known as HotA is a fan-made full scale add-on for Heroes of Might and Magic III, designed to continue the classical Heroes 3 add-on series of RoE/AB/SoD.
The aim of the project is to create an add-on for Heroes of Might and Magic III: The Shadow of Death with lots of new features. The main focus of add-on is the quality of every single aspect of the modded game. This includes the careful fixes of the original game balance, removal of the graphical imperfections left by the developer, and of course, a huge amount of new content, like new campaigns, new map objects and even a new playable faction - The Cove. The project pretends to be fully lore-wise and keeps connection with the original Might and Magic universe.
