Batman: Arkham Origins Blackgate has launched for the PlayStation Vita today, and Warner has released a video showing a little over 10 minutes of footage from the Cell Block section of the game.
In the video a developer explains different aspects of their variation on the metroidvania style of game. It may be 2.5D, but you will be hookshotting and climbing thought he background sections and the game organically shifts focus through the different layers.
In addition they’ve tweaked detective mode with a few new goodies, including using the touch screen to scan and a new number finding hacking mechanism. This is to help with the new perspective.
