The main stories in Batman: Arkham City will take over "25 hours to complete", claims the game's director Sefton Hill. Speaking in an interview with The Guardian, Hill also added the game will offer "around 15 hours of story that's off the main path."
So does this mean that the game clocks in at an impressive 40 hours? Possibly, but this jars with an interview given by Rocksteady's marketing game manager, Dax Ginn, who told Computer and Videogames earlier this week that the campaign takes around eight hours if you're a gaming ninja.
What's more likely is that the 25 hours accounts for the 15 hours of side missions plus a 8-10 hour campaign. Either way, it sounds like a lengthy tour of the scum-riddled streets of Gotham lies ahead.
Batman: Arkham City will be released for PC, Xbox 360 and PS3 in late October.
