Fatal Experiments, subtitled "Three Investigations into the Sinister and Macabre", is a collection of three adventures published by Chaosium in 1990 for the horror role-playing game Call of Cthulhu, itself based on the works of H.P.

[3] Chaosium first released the horror role-playing game Call of Cthulhu in 1981, and regularly refreshed it with new editions containing revamped rules.

In Issue 26 of White Wolf (April/May, 1991), Wayne Ligon found the article on black powder weapons "interesting, useful, and well researched."

Ligon concluded by giving this book a rating of 4 out of 5, saying, "This adventure introduces a new Lesser Servitor Race and has quite a few nice rewards for anyone alive and sane enough to collect them.

"[2] A copy of Fatal Experiments is held in the Edwin and Terry Murray Collection of Role-Playing Games at Duke University.
