Arkham Knight expansion available today

　　* Wonderland: The Mad Hatter makes things personal as the Super-Villain lures Batman into a demented, hallucinatory battle of wits across Gotham City and within the pages of a twisted story book.

　　* Beneath The Surface: The World’s Greatest Detective and Nightwing venture out to investigate Iron Heights, a flying airship prison that housed Killer Croc, after it crashed in the waters surrounding Gotham City.

　　* Shadow War: Picking up after the events of Batman: Arkham City, Batman’s devout moral code is pushed to its limits as Ra’s Al Ghul’s health rebounds with the help of the League of Assassins.

　　* In From The Cold: Mr. Freeze returns to Gotham City, where he is immediately entrapped in Arkham Knight’s Militia and Scarecrow's plan to destroy Batman. Arkham Knight’s Militia has kidnapped Nora and will return her to Mr. Freeze in exchange for Batman’s capture.

　　Batman: Arkham Knight was released back in June of this year for PC, PS4, and Xbox One. The PC version however, was quickly suspended due to performance issues. On the official WB forums, the publisher motivated the decision to suspend future game sales.

　　We want to apologize to those of you who are experiencing performance issues with Batman: Arkham Knight on PC. We take these issues very seriously and have therefore decided to suspend future game sales of the PC version while we work to address these issues to satisfy our quality standards.  We greatly value our customers and know that while there are a significant amount of players who are enjoying the game on PC, we want to do whatever we can to make the experience better for PC players overall.

　　Back in October, publisher Warner Bros re-released the PC version of the game on Steam.
