In Uncharted Waters IV with Power-Up Kit HD Version, players will travel the Seven Seas—including the Mediterranean Sea, East Asia, New World, and more—with their own fleet in the Age of Discovery.

Uncharted Waters IV with Power-Up Kit HD Version includes Uncharted Waters IV: Porto Estado and its Power-Up Kit version, as well as the additional elements featured in the handheld port Uncharted Waters IV: Rota Nova, all remastered in high-definition as a new release. This is the culmination of Uncharted Waters IV.
