Asmodee Arkham Horror the Card Game: The Scarlet Keys Investigator Expansion Myriad dimensions exist layered over our own. Sometimes, when the barrier between these layers is thin, things creep in from the vast beyond. It is up to those with accursed knowledge to stop such entities from tearing our dimension apart. This expansion is a fantastic addition to any Arkham Horror: The Card Game player’s collection, and the cards within can be used to build or enhance investigator decks for any of the game’s scenarios or campaigns.
