Part 6

Follow the linear path to a gate. Little Brother must go between the bars, turn the lever with a rotating/circular motion while holding the interact button to open the gate for Big Brother. The gate will fall if you stop turning.

With both brothers inside, descend stairs to the left and cross a narrow bridge.

At the waterwheel, grab the side bars and drop to the stone level below to the right. Do this one brother at a time if needed, keeping the interact button held down. Repeat for the other brother.

Head east and jump across a chasm. Climb stone levels and jump between platforms to the north, reaching a big bronze gear and a river with a small wheel.

Ascend steps north of the big gear and run east through a 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 to stop it, which in turn stops the small wheel in the water.

To move the pillar, hold both interact buttons simultaneously. One movement stick will be inverse as one brother moves backward. Reorient the pillar multiple times as you move it through the maze.

Haul 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 interact with the big lever and push it forward. You will stop at the middle of the Y-track.

Rotate the lever to face the left Y branch and push it until it hits the stopper. A part of the path will extend.

Push the lever into the other branch of the Y-track to extend the other side of the bridge.

Cross the fully extended bridge, then hop across stone platforms to the north.

Follow the pathway to a huge water wheel that is moving in the opposite direction.

To stop this wheel, hoist Little Brother up to the top level using the half-ladder to the right. Ascend 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 move again. Get Big Brother in position before jumping.

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 a small bridge. Ignore the water fountain and take the left stairs upward.

Go left and through a small 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 the chain ropes and grab onto them. Each brother can only grab one. Keep holding the interact button all the way across, or they will fall.

On the next platform, a big black structure impedes progress. Hoist Little Brother up to the upper level using the half-ladder.

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