The Summons of the Deep expansion to the Call of Cthulhu Living Card Game continues with its second Asylum Pack of 60 fixed cards, The Horror Beneath the Surface. It contains 3 copies each of 20 unique cards that place a newfound emphasis on the Investigation struggle, designed to augment existing decks and add variety to the Call of Cthulhu metagame.

This is not a standalone deck; you must have additional Call of Cthulhu LCG cards to play.
