For fans hoping to see Green Arrow in a console or PC, you will be please to hear (read in this case) what Stephen Amell has to say, as his reply to a fan suggests that we'll see Green Arrow in the upcoming Batman: Arkham Knight.
This is not his first hint towards it, since, last week, after Sony's E3 2014 conference, where gameplay of Arkham Knight was unveiled, Stephen posted an image of what appears to be "Grand Theft Auto: Starling City", suggesting not only his role in the upcoming Arkham Knight (open world here, being the common denominator), but also his interest on a Arrow inspired videogame. Also Stephen is no stranger to videogames, voicing Green Arrow's Arrow skin in NetherRealm's Injustice: Gods Among US.
Stephen's post on his Facebook page.
Batman: Arkham Knight is still without a release date, since it was delayed to 2015 several weeks ago, though animated Batman, Kevin Conroy is saying that the game is coming January, though, if there's any truth to this, it's still unconfirmed by higher-ups at WB Games.
