Arkham Horror: LCG - The Drowned City: Campaign Expansion

Arkham Horror: LCG - The Drowned City: Campaign Expansion is a campaign expansion that sends investigators into the rising ruins of R’lyeh for a branching, high-stakes confrontation with Cthulhu.

Across the full campaign, one to four investigators explore shifting corridors, alien machinery, and sea-floor horrors as the city emerges from the deep. Early on, you’ll choose whether to approach R’lyeh from the east or the west, changing the order and setup of what comes next. Each investigator also begins with a personal Task that adds side objectives and story beats alongside the main mystery, giving every run new angles to chase. Designed for 1–4 players ages 14+ with an average play time of about 90 minutes, you only need the Arkham Horror: The Card Game Revised Core Set to play. Available now at Boarding School Games—dive into R’lyeh and face Cthulhu.
