Throwing the switch here will change the directions of the two gears in the room. You will need to throw it once, so that the gear on the right is rotating upwards, and then throw it a second time. Quickly jump up to the cog and then across to the ladder before the cog builds up too much speed. At the top of the ladder jump onto the left hand cog, ride it to the top and then use one of the cogs teeth to jump up to the platform above.
Run to the left and ignore the lever for now, continue past the cart with the ladder and jump up the other side. Continue onwards and in the far right side of the area you will find a mine cart. Pull it back to the left and leave it to sit beneath the lever that is visible near the top of the room.
Run back to the cart with the ladder. Push it as far as possible to the left hand side. Climb up the ladder and ride it to the left. Jump out and head to the switch. Wait for the cart to reach the other side of its pit and then turn on the power switch when the cart-ladder is almost at the left hand side of the area. Jump onto the ladder and ride it back to the right. The platform beneath it will rise and allow you to jump from the ladder onto the platform above and to the right.
Once on the platform, move to the right and jump to the switch across the gap. You should fall safely into the mine cart below.
The mine cart will start to move forward. After a short while, you will see a ladder approach in the dark. Jump up to it and get onto the platform above. Let the mine cart get slightly in front of you and follow behind it. A circular saw will start tearing up the platform you are standing on, when safe to do so, run and jump over the saw into the mine cart below.
When the mine cart leaves the electrified floor, jump down to the solid ground below. Do not jump up onto the ledge, as the mine cart will continue into an alcove, hitting a switch here and electrifying said ledge above. When the minecart comes to rest, pull it out of the alcove and push it up the hill to the left. When you push it, it will continue upwards for a few seconds, before itstarts to roll back down the hill towards the switch again. So push it uphill slightly, then jump onto it and from there quickly jump up to the platform above, being sure to run and jump as many times as possible to get to the otherside of the electrified floor ASAP (ie before the cart hits the switch!).
Time for another level rotation puzzle! This time we have a swinging light that makes it very hard to see what we are doing, it can be a little frustrating but once you know what to do it is quite simple. When ready, pull the switch here and then jump across the gap on the right when able. Run to the right and stop on the small even section between the two slopes, wait for a bit more of a rotation, and then jump across to the ladder above the gap on the right. Move up the slope slightly, and wait for a little more rotation before jumping to a safe platform just above the electrified floor. The rotation will stop.
Achievement/Trophy: In front of you, you will see an electrified wall, and in front of it a hard to spot wooden crate. Push this up against the electric wall and get on top of it. Jump to the left to climb up onto a hidden platform. From here jump to the ledge above the electric wall to find an egg for the achievement/trophy - Guided by SparksĀ.
Push the crate off the ledge to the left and jump down onto it and across to the platform. Continue to the right.
