OGPlanet is ceasing operations of Uncharted Waters Online on September 29th. However, Papaya Play is picking the nautical MMO and will set sail on October 18th. The content release schedule already in the works, including the Revolution expansion, will begin again after the new service starts on the 18th. It seems that accounts will be transferred to the new host and "OGPlanet is inviting players to refamiliarize themselves with their OGP IDs and passwords" in preparation.
The Papaya Play Team is excited to announce that Uncharted Waters Online will soon be setting sail on Papaya Play! Embark on an exciting voyage around the globe and through the ages in this epic seafaring sandbox MMORPG with near-endless possibilities.
