⚔️ Heroes of Might and Magic III: ERA Project (English Version)

Welcome to ERA Project — a modern platform for Heroes of Might and Magic III modifications.
ERA continues the ideas of WoG (Wake of Gods), maintaining backward compatibility and providing powerful tools for modders, scripters, and plugin developers.

🧩 What is ERA

ERA is a modular enhancement for the original Heroes III that expands the game’s capabilities through:

• 🔹 ERM 2.0 — an improved scripting language for events and logic;
• 🔹 C++ plugins (via the ERA API);
• 🔹 Modular mod-loading system;
• 🔹 Better compatibility with HD Mod and modern systems;
• 🔹 Flexible customization of random maps, objects, and UI.

ERA serves as a core engine upon which you can build large-scale modifications
or lightweight plugins that change gameplay, visuals, or object behavior.
