The free-to-play title arrived on Steam back on December 19th along with a leveling event to get new captains up to speed. You still have a few days to take advantage of these XP buffs, by the way, since the event ends on January 2nd.
Uncharted Waters Online originally released back in 2004 as part of a long-running nautical RPG series. The title was taken over by Papaya Play, which relaunched it back in 2017. Right now, Papaya is running a contest right now to see if players can guess the next “Age” that is coming to the game in 2019.
