Part 6

Follow the linear path to a gate. Have Little Brother go between the bars, turn the lever with a rotating/circular motion to open the gate for Big Brother. Keep the interact button held down until Big Brother is through, as the gate will fall if you stop turning.

With both brothers inside, go down the stairs to the left and across the long, narrow bridge.

At the end, find a turning waterwheel with gate-like bars. Grab the bars and drop to the stone level below to the right. Do this one brother at a time if needed. Keep holding the interact button throughout the ride down; they will automatically drop off. Repeat for the other brother.

Head east and jump across the small chasm. Climb up the stone levels and jump between platforms to the north to reach a big bronze gear and a river.

To cross the river, you must stop the small wheel fins by stopping the big gear to the left.

Ascend the steps north of the big gear and run east through the maze-like area with red tanks.

At the other side, find a long pillar lying on the ground. You need to bring this pillar to the big gear and cram it in to stop it, which stops the small wheel in the water.

Control the pillar by holding both interact buttons simultaneously. One movement stick will be inverse as one brother moves backward. Reorient the pillar multiple times as you navigate the maze.

Move the pillar north, then south, then east, and finally down the stairs to the big gear. Walk perpendicular to the gear and wedge it in the shaft to stop the small wheel.

After crossing the river, follow the path down two sets of stairs to a "Y" shaped track contraption with a big lever and two small stoppers.

Use both brothers to grab the big lever and push it forward. You will stop in the middle of the "Y" track.

Rotate the lever to face the left "Y" branch and push it until it hits the stopper. This extends one part of the path.

To extend the other side, push the lever into the other branch of the "Y" track. The bridge will fully extend, allowing you to cross.

Cross the bridge and hop across stone platforms to the north. Follow the pathway to another huge water wheel.

This wheel is going in the opposite direction, so you cannot simply grab it. You must stop it entirely.

Hoist Little Brother up to the top level using the half-ladder to the right. Ascend the steps and hop onto the inclined level with a small gold platform.

Leap from the gold platform to grab the chain with the gold hook. Hold down the interact button to stop the water wheel. If you let go, the wheel will start moving again.

Get Big Brother in position before jumping to grab the chain. While Little Brother holds the chain, use the grate of the wheel to climb up as Big Brother.

With both brothers up top, head east and cross the small bridge. Ignore the water fountain and take the left stairs upward.

At the top, go left through the path with rock formations. You will reach another lever track that operates chains to the left.

Push the lever to the stopper to start the chain ropes. Walk down to them and grab onto one chain with each brother. Keep holding the interact button all the way through, or they will fall.

On the next platform, a big black structure impedes progress on the chain-track. Use the half-ladder to hoist up Little Brother to the upper level.

As Little Brother, rotate the small, white lever on the gold platform. This will open the black structure, allowing Big Brother to use the chains to the next platform. Keep rotating the lever until the structure is fully open.
