Captain Sonar Board Game Extra Maps - Chicago Map & New York City Map

Hands down, this is by far my favorite game right now. It is billed a a boardgame but feels more like a LARP (100% in a good way). It really puts you in the head space of dueling subs. I just wish I could reliable get 8 people together more often.

Good design. You will enjoy this game only when you totally understand the rules. The most important thing is both teams must be self-discipline during the game because there won't be a judge which can stop any cheating.
