Arkham City campaign lasts 8 hours
But only if you're a "ninja".
Forthcoming superhero sequel Batman: Arkham City will take at least eight hours to complete, developer Rocksteady Games has announced.
Brilliantly monikered marketing man Dax Ginn told CVG that that number only applies if you know the game back to front and ignore any of the side missions on offer.
"It's very difficult to put a number on it," he explained.
"I can tell you that our QA guys, who are ninjas and obviously know everything in the game, can do just the core story missions, nothing else, in about eight hours, just straight-lining.
"And they know exactly where to go what to do - the most efficient way of doing it. So, someone who has no idea what to do and wants to complete everything it's going to be significantly more than that."
The keenly anticipated follow-up to acclaimed 2009 adventure Arkham Asylum launches on PC, PlayStation 3 and Xbox 360 on 21st October. Trailer below, should your appetite need to be further whetted.
