Robin, a more divisive sidekick has not been brought into existence since he first joined forces with Batman. DC have tried changing Robin so much to fit in with his times from Boy Wonder to Badass to Girl Wonder back to Boy Wonder. Point, there have been many Robins.
Anyway, back to the news that Robin will be a playable character in Batman: Arkham City. It must be stressed that this news has not come from official sources but instead an innocent shop listing on the Best Buy website.
So, it seems Best Buy has become the new villain when it comes to games leaks. I’ll contact Rocksteady to try and get some sense of this.
