This new expansion brings investigators back to the classic neighborhood of French Hill while sending them beyond our reality, into the depths of the terrifying underworld. Two new double-sided maps bring to life the ancient regions of Arkham, Massachusetts, including the aforementioned French Hill neighborhood, as well as the underworld itself. Four more investigators join the party, from steadfast soldier Mark Harrigan to confident aviator Winifred Habbamock.

The investigators' task won't be easy - this expansion brings three entirely new scenarios, challenging investigators with restless minds, secret cultists, and the depths of the underworld itself. With over 130 new encounter and event cards, new perks, monsters, conditions, and a new type of card tile, Secrets of the Order opens a portal to a wealth of content, drawing you into truly terrifying stories.
