Batman: Arkham Origins Blackgate - Deluxe Edition is an action-adventure game developed by Armature Studios. It is the direct continuation of Batman: Arkham Origins and is a canon installment of the Batman: Arkham series.
Three months after his first encounter with Joker, Bruce Wayne comes across the Catwoman who stole documents from a secret government organization. She is put in the Blackgate prison with the help of Batman. Two weeks later, the prisoners attempt an escape. The prison's staff is taken hostage, and the security detail is dead. Catwoman agrees to help Batman save the hostages.
Unlike the Arkham game series, Blackgate is a 2.5-dimensional game, like Metroid and Castlevania. However, the game does not use any features of such dimension and plays out like a usual 2D title.
The Protagonist walks from right to left clearing the prison out, saving the staff, and completing side-quests like finding items. Items can be detected using Batman's Detective Vision.
When Batman walks into a new area of the prison, there a chance of encountering a group of prisoners, which will attack him. All the enemies, apart from bosses, require two or three hits to be knocked out. Most of the game's fights can be avoided by using stealth. When the player clears a certain area of the prison out, it will remain clear of enemies until the end of the game.
