HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Who knows what this is related to: I rearranged the HDmod because on the Geyrenzh platform, I could only communicate with opponents in Russian – the English language wasn't switching at all. As expected, I renamed the executable file and created a path for the game on the mod, but it simply doesn't launch in the specific multiplayer mode for that game. There's no connection, basically.
