In order to accommodate the new Batmobile the game environment Xbox One owners will get to play around in when Batman: Arkham Knight eventually arrives will be 5 times larger than what they got to experience in previous games in the series.

That statistic comes by the way of gaming website IGN, who talked with representatives from Batman: Arkham Knight developer Rocksteady Studios about the game. According to Rocksteady’s Guy Perkins, the studio has always tried to balance the tight game play that users loved from chasing the Joker around Arkham Island in Batman: Arkham Asylum with trying to enable new ways to get around.

“It was always missing but wouldn’t have worked in Asylum or City, so to build an open-world around that was crucial.”

“So that had its place for that story, but then we took that into the open world to give players the next piece of the Batman armour as it were, which is the grappling gun and the ability to glide. The introduction of those pieces really required a bigger game world to support them, but then the big thing that was always missing for us was the Batmobile. It was always missing but wouldn’t have worked in Asylum or City, so to build an open-world around that was crucial,” Perkins told the media outlet.

Earlier this year Rocksteady revealed that Batman: Arkham Knight players would get to pilot the Batmobile in the game. This will be the first time players have been in control of an actual vehicle inside the game world. Batman: Arkham Asylum featured an earlier version of the Batmobile but players only opened the trunk. Another cutscene only gave players a glimpse at the Batwing.

Thanks to a delay Batman: Arkham Knight will launch sometime in 2015. When it does it’ll be exclusive to the Xbox One and Sony’s PlayStation 4 in the living room.
