We've gotten our hands on some footage that appears to be for Ubisoft's Beyond Good & Evil 2, the sequel to the underappreciated 2003 title.
The footage shows a woman dressed very much like Jade was dressed in the 2008 announcement teaser for Beyond Good & Evil 2, running through a rundown looking town, avoiding police, climbing on top of a building and then making her ultimate escape via an orange helicopter. The visuals certainly match what little we've seen of the game so far.
A tipster directed us to the video. If this turns out to not be from Beyond Good & Evil 2, I'd suggest Ubi steal it and use it, as it looks amazing.
Thanks Alan for directing us to the vid!
