The game was announced and revealed at PlayStation's E3 2014 press conference, with the first gameplay shown in Batman: Arkham Origins, which became the game's principal commercial success, leading to the initiation of the Arkham series' successful Arkham franchise. A playable demo with the Batmobile for the Xbox 360 was made available to fans at the Game Developers Conference in March 2014, while the game's full release was confirmed three days later. In June 2014, the PC version was released for digital download from, with the developer's Xbox One and PlayStation 4 release set for late 2014. Although Arkham Knight would be the last game in the Arkham series to be developed primarily for the Wii U, a port for the Wii U was published by Nintendo in 2014, after Warner Bros. requested that the company make a port for the console. The Steam release of the game on the PC was portaced by developer Rocksteady subsidiary DICE, which had maintained an interest in the series since the release of Arkham City. The Xbox One version of the game uses the Kinect in addition to the license to Batman's voice and movements, which the developers used to dynamically change the game's camera angle depending on the player's actions; this was a departure from the previous games in the series, in which motion-based controls were used and the camera fixed during gameplay. One major change introduced in Arkham Knight is that the player can now find NPCs to talk to and allies to assist them in combat, as a way of motivating the player to complete secondary objectives. In addition, the game introduces one-handed combat, which allows the player to use the focused version of Batman's cowl without the need to hold the controller.
Unlike Arkham City and Arkham Origins, the player cannot freely roam around Gotham City with the Batmobile, as the vehicle is detached from the player's Batman. Instead, players move around the map, fighting the enemies and city's inhabitants while completing story-based objectives, which are accompanied by cutscenes that involve Batman alongside partners from the Arkham series. After completing an objective, the player enters their car to return home, before the story's final finale. A major change seen in the game is that, because of the lack of the ability to freely roam, voices for characters other than Batman were entirely redone by providing them with a difficult combination of voice and lip movement. 7211a4ac4a
