Kreuzzüge: Ritter im Heiligen Land (2011)

(from the back of the book)
The social and military clash of christians and muslims from 1095 to 1291 takes its bloody toll in 7 crusades, countless smaller wars, civil wars and intrigues. The land from Constantinople to Egypt is the stage of countless invasions, fights and revolutions. Especially, of course, the Holy Land.
This book should lead th game master ind his players into a very dark mixture of real history and a cthuloid variant of teh arabian nights. As, like every so often, the crusades show that the biggest enemy of man is not man, but the evil from beyond the stars.
Detailled hints for keepers, new occupations and oprional rules for mass battles cerate the opportunity to fight on both sides of the war.
An introductionary adventure and a mini campagne confront the player characters with abhorrent events during the first crusade.
