The GOG game preservation program has expanded — "Heroes III" is now recorded on a unique medium, a crystal coin, developed by SPHotonix.

The crystal coin can last for billions of years and withstand extreme weather conditions.

The GOG game preservation program has also included "Heroes II" and "Heroes Chronicles".

Additionally, "Heroes V" has gained Czech, Hungarian, and Simple Chinese localizations.
