Expansions
Expansions typically refers to official additions, Armageddon's Blade and Shadow of Death, which both connect to the storyline of the Heroes of Might and Magic III: Restoration of Erathia. Both expansions may be installed independently of each other, and require the original game in order to work. Sometimes Heroes Chronicles is considered to be an expansion, although it is more aimed as an introduction for beginners to the Heroes of Might and Magic -series. The Heroes of Might and Magic III Complete is a collection, that inculded the original Restoration of Erathia game and both expansions Armageddon's Blade and Shadow of Death.
- Wake of Gods - Unofficial and perhaps the most popular unofficial addon, which adds a lot of new features.
- HoMM3 HD mod - Addon pack for Heroes of Might and Magic 3 and the expansions, which mainly improves the user interface, adds new functionality and repairs some original bugs.
- VCMI Project - The goal of the project is to rewrite the entire H3 engine (VCMI is NOT another mod) giving it new possibilities.
