Batman: Arkham Origins - Blackgate

Well interestingly enough the WB is releasing an Arkham Origins handheld version... kinda. This game is set in Blackgate prison and seems to feature a variety of characters from all three Batman Arkham games. The plot comes across as a rehashing of the first game to be completely honest. You'll notice from the trailer that it's a side scroller at times, but it could still be interesting. It's being released on the Playstation Via and Nintendo 3DS on the same day as Batman: Arkham Origins, which is October 25th.
