Heroes of Might and Magic III: The Succession Wars

Heroes of Might and Magic III: The Succession Wars is a total conversion of Heroes III dedicated to the fairy-tale atmosphere and graphic style of its prequel, Heroes II. The modification adds a lot of new content, such as creatures, castles, and artifacts to name a few, and provides fresh gaming impressions as well as a great amount of nostalgic feelings at the same time.

The Succession Wars installation

  1. Install and run ‘H3SW_v0.8.2_Installer.exe’. Install H3SW to a folder with a CLEAN Heroes 3: Shadow of Death or Heroes Complete game (No HotA, no HD Mod, no WoG, no ERA can be installed in that folder already!).
  2. After the installer have finished go find ‘H3SW_v0.8.2’ in your selected folder and start playing!!
  3. Pick ‘H3SW – Map Editor’ for the Map Editor tool.
  4. Optional: You may now install Heroes 3 HD Mod on top of your selected folder, if you wish to play in HD.

If you cannot launch h3sw.exe for some reason on your computer (like getting the WINGRAPH.CPP error), you will also have to use Heroes 3 HD Mod (not Heroes 3 HD Edition).


Succession Wars v0.8.2
Heroes 3 Complete GOG version (works only with this version)
or try WoG Folderonline source of Heroes of Might and Magic mods (not only Heroes 3 mods, but not Heroes 6 😀 ) and various goodies (like “Did you know” series) that I have managed to collect over the last 10 years for everyone who contributes to the running of the Heroes 3.5 Portal.

    Super ale nemám tam kampaně??Poradí mi někdo jak je tam dát?Díky

    1. Liso1 (Post author)

      Kampane ešte nie sú súčasťou modifikácie, ale pribudnú, aj keď neviem kedy, pretože mod už veľmi dlhú dobu nebol aktualizovaný.

      Ak chceš hrať kampane Heroes 2, určite skús toto: https://heroes3wog.net/free-heroes-of-might-and-magic-ii-resurrection/

    Played around 20 maps, absolutely fantastic expansion. Anyone who likes HoMM2 over HoMM3 will love this since it runs on the HoMM3 engine, which gives a tremendous amount of improvements. I was surprised that I want to play it this much.

    It is way more balanced than the original adding one unit and tweaking stats of existing ones. A truly well-made mod.

      I can only agree with you. I hope that the development will move on and we will also get the Inferno faction, which is currently missing.

      campaigns are not yet available

    I just can’t make it work. I bought HOMM3 Complete on Gog, installed as said and I still get this error:

    Assert violation in file “D:\Soft\Programming\Delphi\Source\SRC\Units\_OLDER_\GameExt.pas” on line 407.

    Error at address: $5F118A5.

      Try running the game via HD mod. It is not recommended to have Heroes 3 Complete base game installed in C: Program Files.
      A new version of the SW modification should be available soon. I’m already waiting for it so that I can then make a better video tutorial.

      1. Chris

        Just fyi, the animation speed in combat is way to slow, it really hurts the gameplay, would recommend at least doubling it on the fastest setting.

      2. David

        I tried with the new version 0.8.2 and I still get the same error:

        Assert violation in file “D:\Soft\Programming\Delphi\Source\SRC\Units\_OLDER_\GameExt.pas” on line 407.

        Error at address: $5BD18A5.

        I tried to put the hd mod as well and it still doesn’t work. I get the same error. Also tried installing it on another elsewhere and not in C. Same error

  6. David

    I tried it all. Not installed in C, and also tried HD mod. Still same error as mentioned above 🙁

    game should not be installed in either of these 2 locations, 1) not in root directory of harddrive, means c:\HOMM3 – would not work, 2) not in Program files x86 directory.

    example which would work – c:\myfolder\HOMM3
