Why has the game Batman Arkham Origins been removed from Google Play Store? When will it be available again?
The game hasn't been removed from Play Store, only that's not available for the country you're in. I've accessed the official link and an error appeared saying that the game is not available.
It's impossible to say when the game will be available, but the only way to see is to check periodically the following link: https://play.google.com/store/apps/details?id=com.wb.goog.batman.brawler2013
