Campaign for Shades of Darkness: The Fall.

Here are a few tips on setting the difficulty level. Chapters 1 and 2 are quest maps; use 80% or 100%, otherwise, a large number of monsters may block the path during the weekly growth phase. In Chapter 3, you can experiment; you should have enough troops to handle the weekly monsters. In Chapter 4, the troops of allies and enemies are balanced; use high difficulty levels. In Chapter 5, the hero is well-leveled; choose any difficulty. In Chapter 6, set the difficulty to the maximum.
