Upcoming game Batman: Arkham Origins is likely to get two new assassin characters ahead of its Oct 25 release.

The game sees Black Mask, the crime lord announcing a reward for eliminating Batman, the game's protagonist.  Until now, WB Games Montreal, developer of the game has shown the participation of villains like Bane, Deadshot, Deathstroke, Copperhead, Firefly, Joker, Penguin, Scarecrow, Killer Croc, Anarky and Mad Hatter, who try their luck eliminating Batman.

With the achievement list of the game being leaked on Exophase, Riddler Trophy is reportedly one among the trophy list, for players to collect, according to Coming Soon. The report also notes that apart from Riddler the other assassin is Lady Shiva, who was created by Dennis O'Neil and Ric Estrada and happens to be one of the most talented assassins in the DC Comic Universe.

The game also introduces multiplayer mode in the series for the first time. GameNGuide says that the multiplayer fight in the game is between Batman's better gadgets and stealth pitted against enemy firepower.

The Batman in the game is younger and has completed only two years as a crime-fighter of Gotham City and is yet to earn the trust of the police as a superhero. Batman will also be meeting Batgirl and Captain James Gordon for the first time. The game shows his transformation from a crime-fighter to the Dark Knight.

This game is a prequel of 2009's Batman: Arkham Asylum and 2011'S Batman: Arkham City. The game will be coming out for PC, Wii U, PlayStation 3 and Xbox 360 on Oct 25.

Nintendo 3DS and PlayStation Vita will be receiving Arkham Orgins' companion game, Batman: Arkham Origins Blackgate which is also due for Oct 25 release.
