Ubisoft released Assassin's Creed Black Flag RE:Synchro on July 9, 2026, a remake of the 2013 title Assassin's Creed IV: Black Flag. The game is available on PC via Steam, Epic Games Store, and Ubisoft Store, as well as on PS5 and Xbox Series X|S, and through the Ubisoft+ subscription service. Within its first hour on Steam, the title reached approximately 100,000 concurrent players, the highest ever recorded for an Assassin's Creed game on the platform. Ubisoft subsidiary Vantage Studios later announced that the remake sold 2 million units on launch day. The remake uses the latest Anvil engine, with improvements to combat, naval battles, stealth, and parkour, and adds new story content centered on Blackbeard and Stede Bonnet. Despite the strong launch numbers, Steam user reviews initially landed at a "Mixed" rating with about 66% positive ratings, driven by issues such as the inability to select non-English voiceovers at launch and a bug locking cutscenes at 30 fps. Ubisoft has since resolved the voiceover issue and acknowledged the cutscene bug, with a fix in progress. As of July 11, user reviews had recovered to "Mostly Positive" with 73% positive out of over 8,000 reviews.
The remake of Assassin's Creed IV: Black Flag, developed by Ubisoft's Vantage Studios, is the first full remake in the Assassin's Creed series. It rebuilds the 2013 original on the latest Anvil engine, adding ray tracing and Dolby Atmos support while refining combat, naval battles, stealth, and parkour. New story content focusing on pirates Blackbeard and Stede Bonnet has been added. The game's Steam concurrent peak of 99,447 players surpasses the previous series records of 64,825 for Assassin's Creed Shadows and over 60,000 for Assassin's Creed Odyssey. However, the launch was not without problems. A bug that prevented players from selecting non-English voiceovers was quickly patched, and a separate issue causing cutscenes to run at 30 fps has been acknowledged by Ubisoft, which advised using preset graphics settings as a temporary workaround. The initial wave of negative reviews, particularly from Chinese-speaking users, also included complaints about promotional strategies and the volume of microtransaction DLC. By July 11, the user review score had climbed to 73% positive ("Mostly Positive") out of 8,070 reviews. The game is available on PC, PS5, Xbox Series X|S, and Ubisoft+.
