PEGI may have spoiled Ubisoft's surprise.
Assassin's Creed Black Flag Resynced has appeared in the database of the European rating organization PEGI. Apparently, the updated version of Assassin's Creed 4: Black Flag will be called exactly that.
Ubisoft has not yet officially confirmed the existence of the game, but the appearance of an entry in the official register of rating organizations usually occurs shortly before the announcement or preparation for release.
Information about the target platforms and release dates of Black Flag Resynced is missing in the PEGI database.
Considering that The Game Awards will take place this week, we won't have to wait long for the official announcement.
