This 3DO Support Page has the instructions and patches required to update the North American versions of Heroes of Might and Magic IV and it The Gathering Storm expansion pack to version 3.0. Owners of the North American version of the Winds of War expansion do not need a patch, as that shipped at version 3.0. The Gathering Storm update from version 2.2 has been mirrored on Gamer's Hell and both 2.2-3.0 updates are mirrored on Worthplaying. Users of other language versions of the game (including UK English) are warned not to use these patches.
