The tale of The Scarlet Keys starts in Arkham with a spread of mysterious disappearances. As animals, objects, and people vanish, so too do they disappear from the memory of those left behind. Only yourself and your fellow investigators remember them—or so you thought. When an enigmatic letter arrives, its author claiming to also remember those who disappeared, it marks the start of an epic journey that will take you around the globe and under the scrutinous eye of the mysterious and deadly Red Coterie.

When we say “around the globe,” we mean that literally. The Scarlet Keys Campaign Expansion adds the game’s very first completely non-linear campaign. After the prologue is over, you and your party decide where to go next, and wherever you go determines what scenario you play. This means that, with the exception of the prologue and the finale (which always occur first and last, respectively), all of the scenarios in this campaign may be experienced in any order. However, you may not experience all of them in a single playthrough, since one of the greatest threats in the campaign is not the Mythos: it’s time.

The Scarlet Keys is the latest campaign expansion to Arkham Horror: The Card Game. Just like with Edge of the Earth, there are only player cards in the Investigator Expansion and only scenario cards within the Campaign Expansion. Whether you want one expansion or both, the world of Arkham Horror just got larger!

The Scarlet Keys Investigator Expansion adds a massive spread of new player cards to the game, including six new investigators!
