While all eyes may be on Batman: Arkham Origins, there's plenty reason to be excited about the 3DS/Vita spin-off game, Blackgate. Set after the events of Origins, the handheld game is being developed by Armature, a studio made up of veterans from Metroid Prime dev Retro Studios. Unlike the console game, Blackgate is a 2D Metroidvania game, which has Batman investigating the titular prison.

Perhaps one of the biggest challenges of adapting the Arkham games to the second dimension is adjusting the well-received "FreeFlow" combat of Rocksteady's original games. Game director Mark Pacini says that Blackgate's combat needed to be built "from the ground up," and takes large inspiration from the 2003 Korean movie Oldboy.
