Batman: Arkham Origins Blackgate is a 2.5D interpretation of the Arkham games by Armature Studio. It features non-linear exploration and a focus on using items to progress, mechanics typically associated with the "Metroidvania" sub-genre.
Received this as a gift and it's been enjoyable so far. Appears to be staying as true to the franchise as a sidescroller feasibly can. 'Comic Book' style cutscenes aren't as cheap/cheesy as they tend to be when used in games (Good example: Max Payne; Bad example: Hard Reset)
