Using the crate from the previous section, have our shadowy friend jump up to the platform with the lever.
Achievement/Trophy: Before you throw the lever, jump over to the large cog to the right. You should be able to climb it. Make your way over to the opposite side of the cog, grab the egg for the achievement - Climbing the CogĀ. Climb the ladder and jump back over the cog to the switch.
Pull the switch on the platform to activate the cog. Push the box up to the cog so it gets taken over to the right hand side. Ride the cog up and jump up to the platform above, grab the crate here and push it onto the cog as well. Ride the cog down to ground level.
To the right is a pressure pad. Stepping on this will make a section of ground rise up on the right. Push one crate as far as you can against the right wall and push the second crate onto the switch. As the platform rises, jump across and use the crate here to reach the ledge above.
Continue to the right. Run past the switch and onto the chain suspended above an electrified floor. Swing the chain back and forward until it is swinging as much as it can. Jump back to the left and hit the switch. Quickly run back and jump onto the chain as it moves. Use the chain to swing to the other side of the electric floor.
Drop down the ledge here.
