Atlantis Treasure

From BoardGameGeek:

Navigate your submarine through the murky depths to find sunken treasure in the new LEGO Atlantis Treasure. Fire at obstacles and block other explorers in a deep sea quest where only one sly sailor will triumph! Be the first player to collect three golden treasures to win the game (four if you are less than four players). Place compassbricks on the board to navigate your sub in the right direction -or place a compass brick to divert one of the other players. -or roll a torpedo and fire at another sub and take one of their treasures...
