What we do get to see is shots of the Dark Knight looking angry while pairing up with a masked figure. Presumably this will be one of the seven assassins Batman will have to fight in the game. According to the official announcement, the rest of the trailer will be released on the 20th of May.
Arkham Origins tells the story of a Batman who has yet to deal with criminals more dangerous than mere mob bosses. On Christmas Eve, seven of the most dangerous assassins in the world band together to take on the Dark Knight, and as the teaser trailer shows, pairing up against them is the first time Batman has had any real challenge. This forces him forces him to grow both in physical prowess and emotionally.
Batman: Arkham Origins will be released on the 25th of October, and is currently confirmed for PC, Xbox 360, Wii U and PS3.
