Duke Nukem Forever Walkthrough Part 2 – Damn! It's Late ...

Once you're out of the elevator, head straight ahead into the Damn It's Late Show. Turn right after going through the doors and follow the corridor past the vending machines and be sure to visit the Employee Lounge. There is a guy in there who flips and gives you an Ego boost in the back of the room by the microwave and doughnuts. Head out of there and to the left to reach the sound stage where the show is being hosted. As you enter the soundstage, a father and son will approach and ask for your autograph. Again, use the shoulder buttons to start and the thumbstick to draw. Put whatever and receive an Ego Boost for your efforts. Head forward and to the left to reach the purple curtain that separates the backstage from the stage itself.

When you get there you find out that the Aliens going to the Duke Burger knocked Duke's interview off the air. This means you need to look into things. Head across the stage to the second purple curtain. You'll come across an actor tearing into someone. Walk up to him, Duke will raise his fist, and punch him. Head up the stairs nearby and open the door. The lights dim a bit as an explosion rocks the building. Head straight ahead  and follow the corridor. Follow the signs on the wall toward the Duke Museum Elevator. Hop into that elevator and hit any button to head on up. Before you reach floor 69, the elevator will shut down. When it does, look to the left of the elevator door to find the emergency box. Use it twice to get a hatch to open to your right. Look to your right to see the elevator door. Force it open and head down the corridor into the Duke Museum. Go up the stairs to the left. When you get to the top, you'll see a number of artifacts from Duke's last encounter with the Aliens. One guy though takes a seat on your throne. Head over and talk with him to find out what he wants. Take his picture using the nearby machine to your right. Now sit on the throne and you'll be taken to the Duke Cave!
