the writing style is a little complex which [...] can make the campaign a bit difficult to get a clear grip on, especially in the early stages. He concluded by giving the adventure an excellent rating of 9 out of 10, saying, "Horror's Heart is a fine example of why Call of Cthulhu remains one of the most popular roleplaying games ever created." In the October 1997 edition of Dragon (Issue #240), Rick Swan thought that this book showcased "all the elements that make Call of Cthulhu so electrifying." Swan called the plot "compelling", the locales "eerie", and the adversaries "mind-boggling". He also thought the "well-staged encounters" and a "surplus of gamemastering tips" made these scenarios "a snap to run." Swan's only criticism was "the limp finale, disappointing after such a provocative build-up," saying it "prevents Horror’s Heart from achieving classic status." He concluded by giving this adventure an excellent rating of 5 out of 6.
