Heroes of Might and Magic III is a singleplayer and multiplayer bird's-eye view and isometric TBS game in the Heroes of Might and Magic series.

In October 1999, the game received the Armageddon's Blade expansion, featuring new creatures, heroes, campaigns and the Conflux town. It was followed by The Shadow of Death in March 2000, with its own set of new creatures, heroes and campaigns. The Shadow of Death is a standalone release by default and includes Armageddon's Blade content, but can only access it if that expansion is installed as well. Official patches maintained feature and balancing parity between all aforementioned releases.

The Complete Edition, which contains the base game and both expansions, was released in November 2000 with a custom 4.0 build (compatible online with The Shadow of Death patched to version 3.2). It is the most widely available version of the game, and is the one which is sold on digital stores.

The game requires the GL wrapper by Verok to resolve compatibility issues. The HD mod is highly recommended and frequently used by the community, as it includes quality-of-life improvements such as high resolution support, a variety of custom graphics renderers, and an in-built modification manager.

Mac OS and Linux

The Mac OS and Linux versions of the game are no longer sold, and existing copies of those are hard to run on modern systems. The easiest solution for running the game on Linux or OS X is buying the Windows version and running it under Wine. Further information on how to do that can be found on AppDB. Alternatively, VCMI can be used to run the game.
