Batman: Arkham Origins Blackgate is an action game that takes place after the events of Batman: Arkham Origins but before Batman: Arkham Asylum. After the lockup of Gotham City's villains, a breakout at the Blackgate occurs resulting in a hostage situation where staff members are held by convicts. The game is designed to be a 2.5D Metroid-Style game and is a completely different experience than that of Batman: Arkham Origins.
Features
As you'll play, you'll notice a lot of the main consoles features, like grappling, 
gliding, crouching and climbing, the batarang and the explosive gel, but implemented in a 2.5D style. Instead of xp, the game relays on an item-based system.
Combat System
The new combat system from Batman: Arkham Origins Blackgate still allows
Batman to move to left or right, but he can also be in the foreground or background. The detective mode has been modified as you can see now sightlines of the enemies, and while in detective mode, Batman will change colour if he is seen or according to his proximity. The game allows players to choose in which order they want to solve the boss encounters.
Side Missions
You can complete side missions to discover what caused the explosion that led to the breakout. The game includes multiple endings influenced by the order in which you faced the bosses. Also, the game contains a variety of suits for Batman, each with different attributes, that are unlocked as you play the game.
