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

Medium_HP, I read about this, but even left Shift + F2 doesn't help! :( True, I overcame it back then by simply loading a previous save (it's always useful to save frequently!) and not entering that town - besides, my hero was still too weak to defeat that nasty enemy! (By the way, the map is interesting, but I'll tell you about it later, when (if) I finish it).
