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

baratorch, I found one unpleasant bug; perhaps it has already been reported, but if not, I'll repeat it because it's important: if you transfer artifacts to a hero with a full backpack using the "transfer all artifacts" button, the artifacts seem to be transferred, but in reality, they simply disappear. If the backpack is not full, everything beyond the full capacity also disappears. Please fix this if possible.
