Blood on the Altar is the third Mythos Pack in The Dunwich Legacy cycle for Arkham Horror: The Card Game. Its sixty cards (including a complete playset of each new player card), challenge you to delve the secrets of Dunwich, where you suspect a series of recent disappearances may be related to the events in Arkham. But the more you explore, the more you get the impression the townsfolk aren't exactly pleased to see you. There are secrets in this town that its inhabitants don't wish to share…This is not a standalone product. It requires the Arkham Horror: The Card Game Core Set and The Dunwich Legacy deluxe expansion to play.
