In Letters Of Marque you command a battleship to save the world from a pirate infestation. Command your crew as they wage war on an army of enemy ships, pillaging and plundering your way to total sea domination. Earn gold, upgrade your ships and weapons and use different tactics to send variety of pirate ships to a watery grave.
