A new "This Ain't No Place for a Hero" trailer from Batman: Arkham City shows off gameplay from the upcoming superhero sequel, including a bunch of villains, concluding with an afterword from the Joker. There's also word on Computer and Video Games from Rocksteady on the length of the game's single-player campaign, saying their game testers can blast through the core game in eight hours because they know exactly how to rush through the game, but for players who don't know their way around and are being more completionist, "it's going to be significantly more than that." The embedded version of the trailer follows.
