Hearts of Oak: Conquest of the Seas is a non-commercial PC game being developed by PiratesAhoy!, and is to become the historical seafaring game to end them all! Fun, realistic gameplay on land and at sea, set during the Age of Sail, will provide extensive free play, exciting scripted storylines and intense multiplayer scenarios.
We've added AI ships and basic damage systems to our latest release, and you can see some examples of that in action here. Notice some sails have been damaged enough to fall off, and ships can now sink if they take sufficient hull damage.
