Easter Egg Spoiler Edit
I found a easter Egg but you have to turn the music off or down. It's regarding those who didn't know that Clayface wasn't the real Joker. During the boss with the Joker if you take a moment you will actually hear the real Joker laughing in the background. It's faint but you can here him. Which hints to you that the Joker your are fighting isn't the real one. I want somebody to post on the Joker (Arkham City) I thought I should point that out.
