After that, you get four actions with your submersible, the main two being to move it around and flip the undiscovered animals to their discovered side, thus making them eligible for scoring points.
Players then take something from that central board, placing their sonar token to claim a quadrant and block other players from it. You draw three tiles from a bag which have various species on them, two go onto your board on their 'undiscovered' side in spaces adjacent to your surface ship, and the third goes off to the central communal board. Set on an alien world, each player moves their surface ship and submersible around their board to discover new marine life.
Perhaps the centrepiece of KimCon #3 was Matt from Paper Fort Games with their new design Fathom, offering it for us to playtest and provide feedback.
