# HoMM3 Horn of the Abyss: reconstructing map-editor classes

> The h3maped project reconstructs C++ classes from the HoMM3 Horn of the Abyss map editor's executable. It uses IDA disassembly, RTTI, MFC message maps and dialog resources to recover class relationships, handlers and fields, recording original addresses alongside the reconstructed files.
