Batman Arkham Knight for the PS4, introduces the Batmobile, as a driveable vehicle. The Batmobile can be summoned to the player's location at will while on foot, or, if airborne, the car can be sent to meet Batman as he lands. The vehicle features the ability to perform jumps, speed boost, rotate on the spot, smash through objects like barricades and trees, and fire missiles that can immobilize other enemy vehicles. Batman can eject from the Batmobile and immediately begin gliding around Gotham City. Some enemies will run away at the sight of the vehicle, eliminating the need for Batman to fight them, and enemies attacking the car can be subdued by its automated tazer defenses. Like Batman, the Batmobile can be upgraded with new abilities.
The Batmobile can also be controlled remotely, be driven in indoor locations, and help with solving the game's puzzles, such as lowering an inaccessible elevator with its attached winch. Gotham City is approximately five times the scale of the open-air Arkham City prison in Arkham City. The game takes place in the center of the city, which is split into three island areas, with various districts such as the neon-tinged Chinatown, and the industrial shipping yard. Oracle has set up her communications headquarters in Gotham clock tower, which also houses a makeshift Batcave. Batman's Batmobile was an aspect of the character that Rocksteady had wanted to include in its other Arkham games, but were limited by technical constraints.
Batman's armor was redesigned to match that of the Batmobile to make them appear visually similar, featuring the same shapes and material, and appear functionally compatible with the high-speed methods in which the character enters and exits the vehicle. The design also added armor over Batman's shoulders, covering the previously exposed cape, to make it appear more feasible that it could hold Batman's weight without failing during gliding. For other returning characters, art director David Hego said that the designs were conceived to keep them interesting after players had seen them several times before in previous games, while the game's autumnal setting also necessitated a change in character clothing over the winter setting of Arkham City.
