Water Tank Walkthrough
1 of 9: After walking across the floating bridge over the main tank, you'll come to a ladder leading down to the lower floor. Explore around it until you find the large round distribution block and the control panel next to it.
2 of 9: Click on the distribution block once to rotate it so that it connects the main tank and tank 1 (the two left symbols), then click on the lever. Now connect the main tank to tank 2 (bottom two symbols) and hit the lever again.
3 of 9: Connect tanks 1 and 3 (top two symbols) and hit the lever, then connect the main tank to tank 1 again (left two symbols, as before) and hit the lever one last time.
4 of 9: Now you can go on past this area and travel through the three smaller tanks via their ladders and hatches to reach the hatch door to the main tank.
5 of 9: To unlock the main tank's door, press the top button on the panel next to the ladder and then set the red counter to 1, the blue counter to 5, and the yellow counter to 9. Now press the top button again, and you can climb up the ladder, enter the main tank, and nab the letter fragment from its case.
6 of 9: Exit the main tank and go back through the three smaller ones to the area with the controls you used earlier. Nearby will be a red button connected to a large green machine. Press the button to refill the main tank, since you can't leave the tank area if the main tank isn't full.
7 of 9: Now go back up the ladder that leads up to the bridge across the top of the main tank and return to the Four Way Tower area.
8 of 9: Oh, but you can't get back into the tower, can you? You'll have to return the water to its moat.
9 of 9: To do that, make your way around to the square building like you did before, then go click on that wheel just outside of it again. That'll refill the tower's moat, raising the bridges that give access to it back into position. Return to the tower.
