You are minding your own business, tending to your mines and mill, when a voice calls to you for help. Unlimited hero leveling. Intended for one player only. Recommended that Player 8 faction remains Haven. For easier gameplay, make Player 2 the same faction as your starting faction.
Known issues with MMH7 and how to remedy them in this game:
1) If the dialogue text disappears too quickly to read, such as when you visit a site or attack another hero when the dialogue is triggered, then save the game then reload. Some of the dialogue is important to advance the quests in the game.
2) If an enemy hero flees during combat and is not allowed to respawn, then all the artifacts that hero was carrying is lost as well. There are three sets of the same artifacts needed to progress in the game, so hopefully your hero should be able to collect one set of them.
