We got some gameplay footage from Comic Con 2012. We were told as long as it was over the shoulder and a players head was in the frame often it was ok. So after filming for a while, some suit came in and attempted to stop me filming. I pointed out that we had been given permission by a staffer and filmed what I needed.
Anyway, enjoy. This was taken from the developers/staff side as they played the Aliens while the convention goers were the Marines. I loved the game and it keeps getting better each time I see it. Look for it in Feb 2013 for PS 3, Xbox 360, and PC.
