Streets of Arkham is an expansion for Mansions of Madness: Second Edition in which investigators must confront the horrific secrets behind Arkham's failing facade of normalcy. From the campus of Miskatonic University to the gang-run speakeasies and storefronts, investigators face threats on both the supernatural and worldly fronts. Only with their wits, grit, and the occasional opportunity to unlock hidden potential can they overcome the threats to the city- and their lives.

This expansion unlocks three new digital scenarios, new digital mythos events, and a new digital puzzle. It introduces a new type of card, Elixirs, and a new type of token, Improvements. The expansion also includes new tiles, monsters, investigators, and new cards to further expand your investigations.
