Book of Unremitting Horror — GUMSHOE Dark Mythos Horror Sourcebook

Some horrors don't come from the cosmos. They come from somewhere worse. The Book of Unremitting Horror is a GUMSHOE dark mythos sourcebook packed with original monsters and threats that draw on a grittier, more visceral strain of horror than traditional Lovecraftian fare. Compatible with Esoterrorists, Fear Itself, and other GUMSHOE horror games.

An essential expansion for Keepers who want their investigators facing something genuinely new and deeply unsettling at the table.
