Chaosium Call of Cthulhu Petersens Abominations RPG Book - CHA23152-H

Chaosium's Petersen's Abominations (CHA23152-H) is a scenario anthology for the Call of Cthulhu roleplaying game, delivering five standalone horror adventures set within the Cthulhu Mythos. Written with direct involvement from Call of Cthulhu co-creator Sandy Petersen, these scenarios are designed to challenge investigators with encounters that go beyond the expected — strange locations, unusual monsters, and situations where simply surviving is far from guaranteed. The anthology suits both Keepers looking to drop a ready-made scenario into an ongoing campaign and groups wanting a series of self-contained sessions without long-term commitment.
