Rockstead's Dax Ginn has dropped a few tantalising snippets on the size of Batman: Arkham City, the role of Catwoman, and something special in store for the Wii U.
In an interview with Destructoid, embedded below, Ginn said Rocksteady has been hard-pressed to create and implement systems to stop the player getting confused in such a large open world.
"That is not a very Batman thing," Ginn said of getting lost. The Bat Signal is just one solution to this issue.
In terms of time, Ginn estimated the base plot might take around 25 hours to complete, while to get 100 percent completion, it may be twice that.
Asked about what role Catwoman plays in the game, Ginn said players control Catwoman for around ten percent of the game - so at least two and a half hours, I guess.
Finally, Ginn responded stonily when asked to comment on a rumour that the Wii U port is "the definitive version" of Arkham City, shaking his head before cheekily nodding agreement that he really wanted to talk about it, but couldn't.
Arkham City is due on PC, PlayStation 3 and Xbox 360 in October., with a Wii U version in 2012.
