In Dead Man Walking you will get an Objective called "Locate the Nanosuit Deep Scan Cradle; Locate Gould." Take the elevator down at the end of the level and go down the hallway. Take a right and look for a security camera and a bank of equipment. Hop the red rope and look for a switch. Hold ACTION to activate the switch and a red light will shine. Head back to the elevator and hop another red rope to reach a second elevator. The switch will be glowing. Hit ACTION again to open it and you will see a strange sight: A CELL disco party in the elevator.
