Warner Bros has released a new Batman: Arkham Origins trailer during the San-Diego Comic-Con.
The latest trailer introduces Copperhead as the third of eight assassins, joining Deadshot and Deathstroke.
The trailer reveals Copperhead to be female, keeping in line with the 'New 52' comic relaunch, though many fans will remember the character as being male.
Origins takes place before the events in Arkham Asylum, when Batman is young and inexperienced. Batman: Arkham Origins is set for release on October 25 for Xbox 360, PS3, Wii U and PC.
Last month we got together with Official PlayStation Magazine's Joel Gregory for his thoughts on the E3 preview of Batman: Arkham Origins where he said it feels "remarkably similar," but "there are new features within the existing Arkham framework."
