Arkham Horror: The Card Game has transitioned through two main release models. Originally, content was released in "Cycles" consisting of one Deluxe box and six monthly Mythos Packs. Since 2021, the game has used a "New Model," packaging all investigator cards in one box and the full campaign in another. Here are the releases in chronological order by cycle and type. 1.
