Main Objective Walkthrough for Chapter 2
This section provides a complete, step-by-step guide to navigate Call of the Elder Gods Chapter 2, ensuring you don't miss any critical interactions or puzzle solutions.
Powering the Diving Equipment
Upon entering the cave, descend the ladder. Inspect all available documents, the dumbwaiter, and the main control panel. Locate the diving suit area and examine the nearby desks for any clues. Your first task is to restore power to the diving equipment.
Follow the yellow wire from the diving suit machine to a green power box. You'll need to flip specific switches to get the gauge into the green zone.
Switches to flip: 2, 3, and 5.
Once the power is stable, place the empty cylinder into the machine. Turn on the power switch, rotate the wheel until the indicator is in the green zone, then press the yellow button to fill the cylinder. Attach the now-filled cylinder to the diving suit.
Navigating the Underwater Chamber
Equipped with the diving suit, proceed to the underwater chamber. Here, you'll find ancient murals; inspect them thoroughly as they contain important notations for future puzzles. Stand on the floor circle to activate the submerged machinery. This action is crucial for powering the black ooze separation device.
Black Ooze Separation Puzzle
This is one of the more intricate puzzles in Call of the Elder Gods Chapter 2. You need to manipulate the water and black ooze machine to isolate four units of black ooze in the second tank.
This puzzle requires careful management of the flow direction. Take your time and observe how each action affects the tank levels.
Steps for Black Ooze Separation:
- Fill the first tank, then send its contents to the second tank.
- From the second tank, send only the water into the small tank.
- Repeat the fill-and-drain process until two black ooze units remain in the second tank.
- Fill the first tank again and manage the flow to ensure the second tank reaches three black ooze units with no water.
- Fill the first tank one final time and transfer its contents to the second tank until it holds four black ooze units.
- Press the vertical-pipe button to send the concentrated ooze upward.
Tower Control Panel (Harry's Piano)
After successfully separating the black ooze, you'll need to use Harry's unique piano-like control panel to manipulate the towers and prepare the statuette. The mural notations in your journal are vital here.
Key Sequences:
- To raise towers: Press 1, 2, 4, 5, then C.
- To rotate towers and reveal the left-tower doorway: Press 1, 1, 4, 4, then C.
- To reset towers back to original position: Press 4, 4, 1, 1, then C.
- To raise towers higher: Press 1, 2, 4, 5, then C again.
- For the clean sequence: Press 1, 4, 2, 3, then C.
- For the fire sequence: Press 4, 2, 5, 3, then C.
Once the statuette is prepared, send it down through the dumbwaiter. The chapter concludes as you continue as Evangeline.
