The "New Horizons" mod for the 2003 Pirates of the Caribbean game by Akella is a continuation of the famous Build mod series. Developed as Pirates of the Caribbean Build 14, "New Horizons" continued where Build 13 left off, adding more new content than ever before.
Redone realism options with explanation on the settings should make for a lot less confusion. And "Iron Man Mode" is now part of the normal settings and no longer a separate, hidden one.
