A French website, by the name of PS3Gen has a picture of the Batman: Arkham Origins Collector’s Edition.
If the website is to be trusted, the collector’s edition will come with a 23 centimeters Collectible Figurine featuring the Bat and Joker (Sorry folks, no Deathstroke here) ; a 3D Steel Box case; the Art of Batman: Arkham Origins book; two pieces of exclusive DLC ; and challenge mode DLC for €99.
OXM has claimed that one of the DLC is an alternate costume for Batman, while another is the pre-order bonus which lets you play as Deathstroke.
The website may be unheard of, but the details of the Collector’s Edition seem to be authentic. You can have a look at the image yourself below.
Batman: Arkham Origins will release worldwide on October 25 for PC, PS3, Wii U, and Xbox 360.
