About the game
What you do in a play session
This promotional map for *Captain Sonar* was handed out at Asmodee’s booth during Gen Con and brings a fresh twist to your game: four double‑sided maps, each with two faces. Two sides feature Captain functions, the other two Radio Operator functions, and they’re split into yellow and green sets. One side of each map is divided into four quadrants, the other into nine, creating varied positioning challenges. The layout depicts the rivers between Manhattan, Long Island, and Staten Island, adding an urban, tactical flavor. As an expansion to the base game, the map preserves the core real‑time combat, deduction, and secret positioning mechanics while offering new routes and strategies that demand quick communication and tactical thinking. The game still runs with 2‑8 players, 45‑60 minutes, and keeps a light 2/5 weight. If you’re already comfortable with *Captain Sonar* and want to spice up the setting, this map is a fun, practical add‑on that will test your deduction and real‑time strategy skills without changing the original game dynamics.
