Batman: The Enemy Within is a point and click adventure game developed by Telltale Games and is a sequel to Batman: The TellTale Series. The series deals with Bruce Wayne’s second year of being Batman, which means he will meet all new villains and come to face to face with old foes. Like the first one, it is episodic and released every a new episode every few weeks/months.

Hey look, it's Batman!
One of the things that I thought really worked nicely with this series was the fact that Riddler wasn’t new to the scene, he was in it years ago and is much older than Bruce. His added years made him a more complex, harder to catch criminal, then he took out one of Bruce/Batman’s most trusted allies, Lucius Fox.

Something that really worked out was Tiffany Fox becoming Batman’s sidekick, it was much different than the typical Dick Grayson Robin one, especially when you learn that she murdered the Riddler and you have to make a choice as to whether to train her or not after finding that out. The story was left open and could bring about a sequel at some point, though with Telltale shutting down, that seems unlikely now.
