LIMBO Egg #4: Chapter 24 [Urban Exploration achievement]

Showing the location of the fourth egg of the game needed to unlock "Urban Exploration" achievement. The picture of the chapter shows the elevator and two control panels. Maneuver the box to the upper level just beside the elevator. Hit the switch so it goes up, and use the box to jump on the very top of the elevator. Jump to the left when the elevator is close to the top (just before it crushes you), and grab the rope to the left. Hang on for a moment until the egg drops. Now jump back onto the elevator and make your way down safely to collect it.
