A mysterious video that resembles the upcoming Batman: Arkham City makes allies out of mortal enemies.
Could Batman fight alongside the Joker, his psychotic arch-enemy, in Rocksteady's Batman: Arkham City? Perhaps, according to what could be a leaked trailer.
A video of what appears to be a cutscene from Arkham City has hit the internet, though its origin is completely unknown. It could be the work of a fan, or it could be an actual scene from Arkham City.
It shows Batman walking down a rain-soaked street, with the Joker waiting for him on the other end. "What took you so long," Joker asks. "It's over, Joker," Batman replies. "Over? Why my dear, delusional Dark Knight, it hasn't even begun," Joker says. The two then go on to beat up a bunch of thugs together, with Batman and the Joker even working in tandem. Batman leaves the Joker standing until the thugs are all unconscious, and then punches the Joker out too.
If the quotes from the previous paragraph sound familiar, it's because they were used in the exact same way during Batman: Arkham Asylum and in Arkham Asylum's trailer. For this simple fact, it makes the video seem more likely to be a fan creation, not that they couldn't be used again in Arkham City.
The words don't make a whole lot of sense in the context of the video though, and while the animation looks good I don't think it's on the incredible level we've seen from Rocksteady in past Arkham City media. Plus, the first teaser for Arkham City showed a feeble Joker that probably wouldn't be able to get up and fight. I'm labeling this one as a fake for now, but that doesn't mean we won't see co-op in Arkham City, or that I can't be proven wrong.
