Batman: Return to Arkham, the remastered collection of both Arkham Asylum and Arkham City, looks like it might be releasing in November.

Although an exact date has not been set in stone, sources told Eurogamer the developer is targeting a November release at the earliest. The game was scheduled to launch July 31, 2016, but WB announced a delay late last month, with no estimated release date.

The delay was apparently due to quality concerns, of which frame-rate issues seem to be a major problem. If issues cannot be resolved in time for a November release, the sources state that Batman: Return to Arkham will appear sometime in early 2017.

When they first announced the delay, WB explained, “After reviewing the progress of the project, the team at WB Games has decided to delay the release of Batman: Return to Arkham to give the team at Virtuos Games additional time to deliver a polished Batman Arkham game experience.  We do not have a release date yet and will be sure to communicate that once we are sure the game will be ready. We know this is disappointing news, but we feel the extra time will allow the team to create the best gaming experience for our fans. ”

Batman: Return to Arkham revisits the critically acclaimed 2009 Batman: Arkham Asylum and the 2011 Batman: Arkham City. Playing as the titular superhero himself, players must use stealth, detective skills and melee combat to take on Gotham’s underground across two stellar sandbox / action-adventure games.

Return to Arkham includes all DLC ever released for either game. While it’s unfortunate to hear that we won’t be returning to Arkham as soon as we expected, it’s good to know that Virtuoso and Rocksteady are taking the re-release seriously.
