Update: It looks like the folks over at CVG have indeed confirmed the video is not real and thus we have pulled it. It was a damn good knock off though.
And the leaks keep coming. Last week it was L.A. Noire and this week it seems that French website Kewego (via gaming site SFX-360) got their hands on a brand new (and unreleased) trailer for Rocksteady’s upcoming game Batman: Arkham City. The trailer has about two minutes of footage and shows Batman and Joker apparently teaming up to take on a couple of goons. They aren’t just fighting guys in the same area either, they are actually working together and doing co-op moves, its freaking awesome!! Hurry up and watch it before they make those guys pull it.
We don’t know if this is just for fun or if this is meant to imply that Batman and one of his most formidable enemies are joining forces but it sure looks like it. This might also be hinting at a co-op mode featuring the two. There is some question about whether or not its real, but honestly if its not then someone is really damn good.
