The game was originally released for PC
Windows on March 3, 1999. both in late December that year. In 2000, a
Game Boy Color port entitled
Heroes of Might and Magic 2 was released. A
Dreamcast port was developed, but not released due to technical issues that prevented the console running the game adequately. This version was cancelled in 2000. A copy of the Dreamcast build was purchased by a private collector in 2005, and in 2020 the collector released it publicly after a brief fundraiser.
Expansion packs Two official
expansion packs were released for
Heroes III. The first of these expansions, ''
Armageddon's Blade'', introduced a ninth town alignment, the Conflux; a random scenario generator, a variety of new creatures, heroes, and structures; and six new playable campaigns. The second expansion,
The Shadow of Death, was a
stand-alone expansion that included
Restoration of Erathia and added seven new playable campaigns and a variety of new artifacts, including Combination Artifacts. Combination Artifacts are formed by combining specific sets of lesser artifacts, granting enhanced abilities. Eight level packs were released as part of the episodic
Heroes Chronicles series. These were stand-alone releases that do not require the base game to play, and were intended for newcomers to the franchise. Four of them were sold individually, two were free downloads and the final two chapters were sold as a bundle in June 2001. All eight installments were re-released through GOG.com in 2011.
Complete edition In 2000, a bundle containing
Heroes III and both expansion packs was released as
Heroes of Might and Magic III: Complete. More than just bundling the original game discs, however, this release reworked the game's installation process as well as its in-game menus to reflect a unified product. The Complete edition does not include the
Heroes Chronicles campaigns, some of which were yet to be released when the Complete edition launched.
HD edition On January 29, 2015, about 15 years after the original release of
Heroes of Might & Magic III,
Ubisoft released a new
high-definition version of the game compatible with PCs as well as
Android and
iOS tablets.
