In June 2024,
Ubisoft chief executive officer
Yves Guillemot said that the company had several remakes of older ''
Assassin's Creed titles in development. Numerous reports highlighted the existence of an Assassin's Creed IV: Black Flag
remake. In September 2025, French outlet Jeux Vidéo Magazine reported that the remake was targeting a March 2026 release. In December, a Black Flag
remake was listed on the PEGI rating board website. Insider Gaming
called the Black Flag'' remake "the worst-kept secret in gaming". Ubisoft publicly acknowledged the project on March 4, 2026, in a franchise update written by Jean Guesdon, the company's head of content. The post included artwork bearing the title ''Assassin's Creed: Black Flag Resynced''. The remake was developed primarily by
Ubisoft Singapore.
Black Flag Resynced includes a fully customizable
HUD with a number of presets depending on player preference. By default, players see enemy health and defense bars which Ubisoft chose to ensure players understand the new defense mechanics. A "Minimal" HUD setting displays only essential information like health and interaction prompts while a "Simple" setting gives aid for combat and navigation.
Writing Darby McDevitt, lead scriptwriter on the original
Black Flag, returned to write two new scenes for
Black Flag Resynced and amend an existing one.
Technology ''Assassin's Creed Black Flag Resynced'' was developed in Ubisoft's in-house Anvil engine for
ninth generation consoles and PC. As such, it utilizes the engine's Micropolygon and Atmos technologies among other visual features.
Loading screens from the original when anchoring in a major city have been removed in
Black Flag Resynced. New footage using modern
motion capture technology was filmed to create more detailed facial animations for Kenway.

Black Flag Resynced soundtrack. == Release ==
