Rocksteady proved that it could bring Batman: Arkham Asylum's unique fighting system into an open-world setting with this year's acclaimed Arkham City. However, recent reports suggest all that unconfined brawling may have resulted in a few bugs in the Xbox 360 version, as a number of users have found their saves, much like Bats himself, disappearing into the night.
In a post to Batman's official forums, Rocksteady said that it has not been able to reproduce the disappearing save issue but that it continues to investigate the reported problem. The post calls for those hit by the bug to answer a number of questions to help pinpoint the nature of the problem.
Most of the information requested pertains to specific versions of the hardware being used and how the game is being saved. The developer would also like to know if the problem occurred prior to or following installation of downloadable content and title updates, and if the issue is happening for those running the fall 2011 system update beta.
Like its predecessor, Arkham City drops Batman in the confines of an unconventional prison. But where Arkham Asylum stuck players in the halls and courtyards of a mental hospital overrun with the Joker's goons and allies, Arkham City deposits them in a sprawling neighborhood of Gotham City that has been walled off to contain the criminal element.
