A new Batman: Arkham Origins character will be revealed later this week, according to teasers and hints left on the Batman Arkham Twitter feed.
The Batman Arkham Twitter announced at the weekend that an "epic" reveal will come this week, accompanied by a series of hints.
The Twitter account has confirmed the reveal has nothing to do with "feline related characters," nor is it revealing "Shark Repellant Bat Spray."
The latest clue came through this morning.
Fan guesswork suggests the reveal will be for Firefly, who will join the already announced assassins Deadshot, Deathstroke and Copperhead.
Set for release on PC, PS3, Xbox 360 and Wii U on October 25, the handheld spin-off title Batman: Arkham Origins Blackgate for Vita and 3DS will be released on the same day.
The Batman: Arkham Origins special edition was revealed last week for North America, Australia and New Zealand.
