Batman Arkham Origins spin-off Blackgate is set to be around 10 hours long with multiple endings according to game director Mark Pacini.
Speaking to The Escapist Pacini revealed that players can choose their own path of progression through the game including the order in which they tackel the game's bosses and players decision will affect the game's outcome.
"It's about a ten hour game first time through. What's interesting is, as we mentioned before that you can defeat the bosses in any order you want, the boss that you leave for last dictates the last half hour of the game. The player will get items he couldn't get before based on who he leaves last.
"You can play the game three times through, get different things each time and the ending is different each time. Along with that we have suits that are only unlockable playing in a certain order. Each suit has a particular perk to it."
Blackgate is due to be released on the same day as Arkham Origins, October 25th, for PS Vita and Nintendo 3DS. The 2.5D game is said to be identical on both consoles with the exception of higher resolution graphics on Vita and 3D effects on 3DS.
