Some interesting things have emerged from that panel. Players will play as Bruce Wayne more than usual in a Batman game. In many situations, there will also be a choice between confronting a situation as Bruce Wayne, or going all in as Batman. As Batman, you'll also be given a choice to physically harm a suspect or take a more diplomatic approach through interrogation to get the information you're seeking. You won't be able to play the whole game without becoming Batman, but the developer's have stated you should be able to play a large portion of it as Bruce if that's the way you wish to play.
It is going to be similar in approach to their The Wolf Among Us series in terms of artistic presentation. It will be set in its own universe. Although it will draw from the 77 years of comic lore that already exists, the team will be able to make their own mark on the iconic characters. It will have an art style inspired by DC artists such as Jim Lee, Greg Capullo and Neal Adams.
It will have an M for mature rating, will consist of five episodes, and will begin releasing this summer.
