Conn...Sonar! is a set of rules for playing (or replaying) movies like "Hunt For Red October" on a tabletop with miniature submarine figures. I didn't write the rules, but I play them regularly, and miss having a discussion place for them since I left facebook. Each player commands 1-2 submarines, and it can be played by email instead of on the tabletop. I'll post the rules, the pdf files for the cards for each submarine, ship, helicopter, or plane, and various other information you need.
