Things are definitely getting weird in Undimensioned and Unseen, the fourth Mythos Pack in The Dunwich Legacy Cycle for Arkham Horror: The Card Game. By the time your pursuit of two missing professors leads you to the scenario from Undimensioned and Unseen, you'll have traveled far from the familiar comforts of Arkham, and you'll have witnessed things you know no one would ever believe. You'll find yourself knee-deep in furtive cultists and their sacrifices, inundated with information about "Ancient Ones" and unholy rituals, and you'll suddenly find yourself forced to destroy terrifying, monstrous creatures that are literally impervious to everything in your arsenal!
