Batman: Arkham Origins pre-order image on Amazon offers Deathstroke as a playable character via DLC. Check it out in a rolling image header here.
Batman and Deathstroke went head-to-head in last week's teaser video, but there was no word on how the striker of mortality would be incorporated into Arkham Origins. This could be a Catwoman in Arkham City situation, where she got an entire spin-off campaign, or it might be something entirely new.
One aspect of Arkham Origins is confirmed today – Kevin Conroy will return as a voice actor.
