Alright, captains! Ready to take your submarine battles to a whole new level? Captain Sonar: Chicago Map is a promotional set originally distributed at the famous Gen Con, bringing fresh maps to your Captain Sonar base game. This isn't a standalone game, but an expansion designed to boost your experience, so you'll need the base game to dive into this adventure.

This pack includes four double-sided maps, split into two sets: one yellow and one green, to distinguish the teams. Each set provides two maps for the Captain and two for the Radio Operator, ensuring everyone on board has a new area to explore and get lost in (oops, I mean, navigate!). The cool thing is that one side of each map is divided into four quadrants, while the other side features nine quadrants, offering different levels of complexity and tactical challenges for your submarine hunts. This means you can choose the intensity of your match, from a more direct duel to a more intricate search.

And the setting? Get ready to navigate the waters of the Great Lakes region, right near Chicago. It's a super cool backdrop that adds a thematic touch to your grid movement and secret unit deployment strategies. If you already enjoy the real-time adrenaline, deduction, and teamwork of Captain Sonar, these maps will inject an extra dose of novelty and replayability into your sessions. It's like getting a brand new battlefield to test your skills and sink your enemies!
