From the publisher's website (translated):
The heroes of Kaphornia are sent on a senstive diplomatic mission to Schwarzfurt, capital of the subterranean shadow empire. Not only do they have to deal with trolls, orcs and other black-bloods, but also with an unexpected sports challenge. It will be a miracle if they come through unharmed.
Das Wunder von Schwarzfurt is a stand-alone game, that will give you and three of four friends three hours of humorous and adventurous entertainment - and for the price of a single cinema ticket!
