I am a bit confused when is the Lego Batman Mayhem mode available? If one has the deluxe edition can one play the mayhem mode already? Additionally any idea what the game mode is about. We seem to just get a vague description of what it is about. Is there any gameplay about the game mode?

What courses do you recommend to help me pass the CCNA? Are the Jeremy IT CCNA books good? Or should I just go to school for it? Any positive feedback is recommended, Thank you.
