06/25/12 - Hi Noel! To turn off the electricity floor, sneak past the security camera by using Batman's Sensor Suit. You will have to stay close to the railing and move fast, because the camera will still detect you if you stay in one place too long. Continue along the railing until you come to a dead-end. At the dead-end, there will be a red computer terminal. When Batman is wearing his Sensor Suit, he can hack these computers. Stand in front of the computer and press the action button to hack it. Use the touch-screen to match the icons to their correct positions. Once the computer is hacked, it shuts down the camera - which also turns off the electricity. Now that the electricity has been turned off, you can flip the switch on the wall. Wait for Robin to pull the second switch and the door will open! Hope this helps! IA
