Game Informer online has released a list of great facts written up by Rocksteady, the developers of Batman: Arkham Asylum, which gives us a unique look into the development processes behind the game, including behind-the-scenes information, as well as details about how certain assets were created for the game.

For example, did you know that the word ‘Joker’ is said 384 times during the game, or that there are 314 breakable televisions in and around Arkham Island?

Well, if you read through the list of facts below, you’ll know all of that and more!
