MMVI: The Chaos Conspiracy is a massive modification for Might and Magic VI: The Mandate of Heaven, which adds brand new plot, quests, graphics and other content, using the classic MMVI world as a basis. The second part of the mod also presents entirely new locations.
A Part 1 walktrough by Jeff and BDJ. Posted on Mod Database for the purpose of back-up. In order to be used only when you are stuck with quests and have 0% chance to quit from the situation by yourself ;)
