Cosmic Horror: Supernatural Horror in Miniature

The stars are right, the end is nigh. Inspired by the works of H. P. Lovecraft, Cosmic Horror takes Spectre Operations players back to the weird world of Lovecraft's 1930's America. Cosmic Horror introduces rules for Sanity, Insanity, strange environmental effects and multiple variations for your Eldritch Horrors - as well as new weapons and investigator abilities to combat them. —description from the back of the book
