Batman: Arkham City
Cancel your meetings! Hang up the phone! Shut down Minnesota's government! The only thing you should be doing right now is clicking the "play" button on the video below.
This uncut 12-minute gameplay clip shows Catwoman in action, Batman's city navigation, and a confrontation with Two-Face and his crew. After Catwoman spits out 10 to 15 groan-inducing jokes, Batman mumbles something to her. I noticed this when I saw this demo at E3 as well. Rocksteady says that they changed his dialogue to hide a spoiler that they didn't want to reveal yet.
I should also note that when Batman is on the rooftop, he is free to explore the city. In my hands on time, I flew to the right and triggered a Penguin confrontation, then eventually made my way to the Two-Face moment shown in this clip.
Batman: Arkham City is scheduled to ship for PlayStation 3, Xbox 360, and PC on October 18. A Wii U version is also planned for 2012.
