The last game of the gaming franchise was recently released as Batman Arkham Knight came out for the PlayStation 4, Xbox One and PC on June 23rd. With that said, the computer version was riddled with major issues that caused Warner Bros. to stop selling the product to new customers until all of the problems could be fixed.
While the PC version is broken, Arkham Knight ran fine on the PlayStation 4 and Xbox One. The game ended up getting solid review scores and became the fastest selling release of 2015 so far.
