Well, I say ‘revealed’, but really they’re just interesting little factoids about Arkham Asylum, courtesy of Game Informer. Some are fascinating, for instance, the combat was initially a rhythm game, then a 2-D fighter, and finally the system which we got, or that cans of whipped cream were used to make the sound of spraying the explosive gel (I knew it sounded familiar). Some are surprising, like the fact that the word “Joker” was said 384 times in the game, or that one of the male producers did some of the mo-caps for Harley Quinn. And some are heartwarming: 6 Rocksteady babies were born during the production of the game. Hit the article for the full list.
