Ubisoft’s Assassin’s Creed Black Flag Resynced has quickly become one of the company’s biggest recent successes, but according to game director Richard Knight, recreating the beloved pirate adventure required far more work than simply upgrading the visuals. Speaking in a recent interview with JorRaptor, Knight revealed that the development team was forced to rebuild nearly every aspect of the 2013 classic because the original technology was incompatible with Ubisoft’s modern tools.
The revelation reinforces why many fans have viewed Black Flag Resynced as a true remake rather than a remaster. Although the game preserves the original story of Edward Kenway, its gameplay systems, visuals, and underlying technology have been extensively reworked using Ubisoft’s latest Anvil Engine.
Ubisoft rebuilt the game because the original code could not be reused
During the interview, Knight explained that the development team could reference the original game’s files but could rarely reuse them directly.
“Sometimes we can occasionally pull an asset as a placeholder or something to model the new stuff. But mostly we just look into the code to see how things work, to look into the data, to see how certain things worked, to learn some of the secrets. But we effectively have to rebuild.”
According to Knight, the technological gap between the original Assassin’s Creed IV: Black Flag and today’s Anvil Engine meant legacy code simply would not function within the new project. Instead, developers treated the original release as a blueprint while recreating systems from the ground up.
He also noted that improvements to stealth, combat, and newly added narrative content were planned from the beginning of development. Those upgrades were not added because the team wanted to modernize selected features, but because rebuilding the game became a technical necessity.
Black Flag Resynced continues Ubisoft’s strong momentum
The extensive redevelopment appears to have paid off. Ubisoft recently confirmed that Assassin’s Creed Black Flag Resynced surpassed 3 million copies sold in roughly one week, making it one of the publisher’s fastest-selling recent releases.
Following the milestone, Ubisoft announced that New Game Plus is in development, allowing players to replay Edward Kenway’s adventure after completing the campaign. While the publisher has yet to reveal a release date or detailed feature list, the mode is expected to expand replayability for returning players.
Originally released in 2013, Assassin’s Creed IV: Black Flag remains one of the franchise’s most beloved entries thanks to its open-world Caribbean setting, naval combat, and memorable pirate storyline. With Resynced rebuilding the experience using modern technology instead of relying on legacy assets, Ubisoft appears to have delivered a remake that stays faithful to the original while embracing current-generation hardware.
