Warner. Bros Montreal had a very specific section of the Batman canon in mind when conceptualising Arkham Origins.
"The main inspiration for Arkham origins is the comic book series Legends of the Dark Knight," creative director Eric Holmes said in a video interview posted on GameInformer.
"It's a series that started in 1989 and followed in the wake of a big trend of going back in time to examine early career years which I think was started primarily from Batman: Year One.
"Legends of the Dark Knight represented really important stories for the Batman mythologies because every time Batman met someone, or encountered some idea in the world - for example, the Venom drug - it was the first time he'd ever run across it rather than the 80th time."
Other inspiration include the already-cited Year One, Frank Miller's much-loved graphic novel, and Rocksteady's work on the previous Arkham games; writer Dooma Wendschuch said in particular the theme of law versus justice - with Batman embodying latter and frequently breaking the former - would be important.
The rest of the interview discusses Batman's relationship with certain characters and the contract of Arkham and Christmas.
Batman: Arkham Origins is due on PC, PlayStation 3, Wii U and Xbox 360 in October.
