Batman: Return to Arkham, the compilation of Rocksteady's Arkham Asylum and Arkham City that's getting the remaster treatment for current-gen consoles was originally scheduled to be released this month. According to a new report over at Eurogamer, the reasoning for the delay and why a new window of November is being targeted all boils down to the quality of the port from from Chinese developer Virtuous Games. And with last year's bungled PC release of the excellent Arkham Knight, Warner Bros. are probably right in being extra careful not to release a sub-standard product.

Currently there's no official release date for the compilation, with Warner Bros re-iterating that they'll have one when they're sure that the game will be ready. Even though Batman: Return to Arkham is a compilation of two previously released titles, both are being re-built using Unreal Engine 4.

Here's the announcement trailer from a while back.
