In 15 Men (on a dead man's chest), a group of dangerous old sea dogs will dispute control of a sea vessel and its precious treasury. Who will win out in the end? The brave captain and his faithful companion, or the mutineers?

15 Men is an intrigue game in which the players carry out their roles in secret, while the captain tries to keep control of the vessel with the help of his guards and faithful sailors. During the game, each player tries to corrupt the sailors who have not yet taken a side, and each sailor has a unique ability that the one who corrupts them can use to change the cards on the table.
