This will allow you to reach the edge of the crushing device to the left. To turn back to the left and 'backtrack' you'll need to push one of the boxes to the right for a bit and then climb on it. Just after losing the brain slug in Chapter 18, you'll find yourself on a conveyor belt. Jump onto the gear and ride it to the right until you reach the egg. In Chapter 16 you'll come to a giant gear with a switch in front of it. You'll need to time your journey into the cave carefully, but after some trademark 'trial and death' you should be able to leap the chasm and get to this egg. If you move deep into this cave you'll fall to your death, however, you can actually leap an invisible pit here. This one is tough: At the end of Chapter 14, after the portion with the spinning saw blade and the two crates, is a dark passage or 'cave' leading away from a ladder. Quickly jump to the rope hanging high up to the left and climb it to reach the egg.

From here, hit the button to bring the car back up and jump left onto the top of the elevator. Take the elevator to the second level and get off, then send it back down to the ground. Drop down on the right side of the metal surface and face left.In Chapter 14 you'll come to a large elevator. Go right to the next wall and climb over it, then walk right across a metal surface as you spot a Secret Egg below. Walk right to what appears to be another wall, but this time climb down the ledge that you're standing on and go right under the wall. Go right once you break through, to find Secret Egg #4 waiting under a beam of light. Keep right to a real wall this time and jump to climb over it, then do a bit of back and forth as you work your way down until you fall down a larger shaft and break through the ground at the bottom. Jump right from the box to reach another ledge, then continue right for Secret Egg #3! Walk right to the wall and realize that it's actually a box in your way, then pull the box left enough that you can climb on top of it. Now you can go exploring down here for three more Secret Eggs. Walk right past a ladder and jump right at the water in the dark tunnel to get the Alone in the Dark Achievement up on a ledge. Ride the rope up and use it to swing to the next ledge on your right. Push the Lever right and jump from the Box to the rope.

Go right and pull the Lever to lower a rope, then push the Box close to the rope. Now the seesaw is weighed down by the elevator, so you can push the Box up towards a new Lever. Drag this left onto the seesaw as the top of the elevator descends. Make the elevator go down and grab the right side of the elevator bottom. Take the elevator back up and push the Box onto the left side of the nearby seesaw. Jump right to the Switch and back left to the ground, then go left to pick up the achievement. Jump left to a rope before you get crushed against the ceiling, which releases the glowing Urban Exploration Achievement. Quickly jump on top of the elevator from the Box and wait near the left side. Hit the Switch to lower the elevator, then hit it again to make it rise. Push the Box right beside the top Switch and leave it close to the left edge. Go past the elevators to a Box and pull the Box left to the elevator and hit the Switch to make the elevator rise, then ride it up with the Box.
