Ubisoft has confirmed that a New Game Plus mode is coming to Assassin's Creed Black Flag Resynced, timed to coincide with the remake passing 3 million copies sold. The milestone marks a rapid rise in sales and is notable because Ubisoft rarely discloses sales figures for Assassin's Creed titles, typically sharing only player numbers, suggesting the publisher is especially pleased with the game's performance despite recent layoffs among the development team.

The 3 million sales figure is up 1 million from the previous week, when Ubisoft reported 2 million copies sold within 24 hours of the game's 9 July launch on PC, PS5 and Xbox Series X|S. No details of the New Game Plus mode have been revealed, though game director Richard Knight said work was underway, aided by the mode already existing in 2025's Assassin's Creed Shadows, and that post-launch support has helped the game maintain a "Very Positive" English-language rating on Steam. IGN awarded the remake 9/10 in its review.
