http://www.batmanarkhamcity.com/ From images, it appears CatWoman is an Ally, and Twoface is an enemy. Coming Spring 2011
only thing is that its still not going to be a actual sandbox game, its still gonna be just the first(game is set in a area of the city that is closed off)
Cool. I wont buy it unless we can drive the Batmobile A Batman based GTA game would be sweet. I'm guessing this game is as linear as the first one though.
Link seems to have been taken down apparently (There's only one image now.) but they were taken by other sites rather quickly. http://www.computerandvideogames.com/article.php?id=262567 http://www.shacknews.com/onearticle.x/65398
Characters are awesome, but the rest looks pretty much the same as in original. Besides, they gotta do better than that in terms of graphics if they don't want it to look dated in a year.
Arkham Asylum is still one of the better looking games of today, IMO. All the improvements I've seen so far look fantastic and I hope it stays mostly linear. You can always tell a far better story that way. I'm replaying through AA because it's so good. Definitely can't wait for this!
