Locating the Generator Key in Chapter 4

In Call of the Elder Gods, Chapter 4 presents a critical challenge: restoring power to the remote facility. Your journey begins in Norway, where Harry and Evangeline must work together to overcome electrical failures and decode cryptic messages. The first step to restoring power is finding the elusive generator key.

Upon arriving in Norway and navigating through the snowy paths, you'll reach a radio tower and surrounding buildings. The generator, vital for power, is locked.

Video Highlights:

  • Identifying the generator building's location near the radio tower.
  • Pinpointing the specific lockbox containing the generator key.
  • A visual demonstration of retrieving the key effortlessly.
Key Location

The generator key is found on the ground floor of the radio tower. Look for a lockbox situated to the right of the stairs. Interacting with this lockbox will reveal the key you need to access the generator building.

Once you have the key, head to the generator building, which is typically located down the hill to the left of the radio tower. Use the key to unlock the building and proceed with the power restoration process.

Restoring Power to the Radio Station

Restoring power in Chapter 4 requires a coordinated effort between Harry and Evangeline. This multi-step puzzle involves activating various switches across the facility.

1

Activate Generator

As Harry, use the generator key to unlock the generator building. Inside, flip the main switch on the generator to turn it on. This will provide initial power, but it won't be fully restored yet.

2

Evangeline's Fuse Box Task

Switch to Evangeline. Climb the ladder in the generator building and interact with the fuse box. You'll need a screwdriver, which can be found on a table nearby. Use it to unscrew the four screws, open the box, and flip the bottom switch.

3

Harry's Breaker Hunt (Part 1)

Switch back to Harry. Follow the red wire from the generator through a wrecked building to a garage. Inside the garage, pull the lever on the back wall. This activates the first external breaker.

4

Evangeline's Fuse Box Task (Part 2)

Switch to Evangeline. You can now turn on the next two switches in the fuse box.

5

Harry's Breaker Hunt (Part 2)

Switch to Harry. From the garage, follow the next wire to the mess hall. Pull the breaker switch located on the right-hand wall.

6

Evangeline's Fuse Box Task (Part 3)

Switch to Evangeline. Flip the switch second from the top in the fuse box.

7

Harry's Breaker Hunt (Part 3)

Switch to Harry. Find the storage building by following the wire from the mess hall. Inside, flip the breaker switch on the back wall.

8

Evangeline's Final Fuse Box Task

Switch to Evangeline. You can now flip the top switch in the fuse box, which corresponds to the radio tower.

9

Harry's Radio Tower Switch

Switch to Harry. Head to the radio tower, go inside, and ascend the stairs. Exit through the door leading to an outside balcony. Climb the ladder, and you'll find the final switch on the right-hand side, past some boxes. Flip it to fully restore power.

Power Restored!

Once all switches are flipped, the radio station will be fully powered, allowing you to proceed with decoding messages and advancing the narrative. This teamwork is crucial for success.

Deciphering Enigma Machine Messages

The Enigma machine is a recurring puzzle in Chapter 4, requiring careful attention to detail and your journal's reference sheets. You'll encounter it first in Harry's flashback, then again in the radio tower.

Enigma Machine in Harry's Flashback

Flashback Setup

  • Locate the coded message on the mail tray near the telephone.
  • Find instruction sheets on the desk to the right of the code box and a reference sheet on the other side.

Deciphering Steps

  • Interact with the machine, noting the first three letters (e.g., GMR).
  • Consult your journal for the corresponding row and dial code (e.g., 25th row, dials 15, 26, 1).
  • Adjust the machine's dials to these numbers.
  • Adjust the plugs (e.g., UA and WF) as indicated in your journal.
  • Pull the orange switch to decipher the message.

During Harry's flashback, you can find a superhero comic in the trash bin behind the desk in the first room for an achievement: "You know what would be awesome? A choose-your-own-adventure superhero game."

Enigma Machine in the Radio Tower

After restoring power, you'll use the Enigma machine in the radio tower to decipher three crucial messages. Collect all code cards and reference sheets scattered around the desks downstairs before attempting this.

Code CardStarting LettersDiscs OrderDial Settings (1st, 2nd, 3rd)Plugs
1UZWII, III, I23, 13, 2GE, FM
2BDAIII, II, I19, 25, 6PW, CR
3SSWI, III, II15, 25, 25ZI, HP
Tricky Code

The third code card has its starting letters ink-blocked. Through careful observation and cross-referencing your journal, the letters are revealed to be SSW, corresponding to January 3rd.

Once all three messages are deciphered, they will be added to your journal, providing critical information for the next puzzle.

Opening the Reinforced Door

With the Enigma machine messages deciphered, you now have all the information needed to open the reinforced door on the ground floor of the radio tower. This door leads deeper into the facility.

Code Logic

  • The door code changes every 10 days.
  • It's a combination of the general's assigned number and the date.
  • If the current general is absent, the previous general takes charge.

Applying the Clues

  • The final communication was on February 25th, meaning the code last changed on February 19th.
  • General Adler was in charge, but he died on January 26th.
  • Therefore, General Hohenberg, with assigned number 95, was in charge on February 19th.
1

Input the Code

Approach the panel to the left of the large red crank wheel next to the reinforced door.

2

Dial Settings

Input the code 9519 into the four dials, starting from the top left and moving clockwise (9, 5, 1, 9).

3

Open the Door

Once the code is correctly entered, interact with the red wheel and turn it to open the reinforced door.

Don't forget to examine the worker's registry and calendar on the wall in the radio tower to confirm general assignments and dates for the door code.

Navigating the Secret Facility and Door Codes

After opening the reinforced door, you'll proceed through a corridor and use a lift. You'll eventually find yourself in a control room overlooking a mysterious black cloud. Your next task involves navigating a flooded section and remotely unlocking doors to bypass a smoke monster.

Door 309N/A309309Unlock as Harry, move Evangeline into Room C (after retreating from Room B)
Remote Door Control

As Harry, use the console in the room with the large window to remotely unlock and lock doors. You can only have one door unlocked at a time. This is key to maneuvering Evangeline past the smoke monster.

Facility Navigation Checklist:

  • Enter the control room and examine documents.
  • Go through Door 'A' and interact with the diving suit.
  • Navigate underwater to a ladder and climb up.
  • Locate the remote door console as Harry.
  • Identify door codes by looking through windows (Harry) and gaps (Evangeline).
  • Strategically unlock doors to guide Evangeline through the facility.
  • Use the red crank wheel in Room C to allow Harry to join Evangeline.
  • Proceed through the final double doors to trigger the cutscene.

Cooperative Success

Successfully coordinating Harry and Evangeline's actions is vital. Remember, Harry controls the door locks, while Evangeline provides the crucial visual information for the codes.

Q: Where can I find the Call of the Elder Gods generator key in Chapter 4?

The generator key is located in a lockbox on the ground floor of the radio tower, to the right of the stairs. Interact with the lockbox to retrieve it.

Q: How do I restore power to the radio station in Call of the Elder Gods Chapter 4?

Restoring power requires teamwork. Harry activates the main generator and external breaker switches in various buildings, while Evangeline manages the fuse box in the generator building, flipping switches as Harry activates external power sources.

Q: What is the code for the reinforced door in the radio tower?

The code for the reinforced door is **9519**. This is derived from the general's assigned number (Hohenberg's 95) and the date the code was last changed (February 19th), as General Adler was deceased.

Q: How do Harry and Evangeline work together to unlock doors in the secret facility?

Harry uses a remote console to unlock doors, while Evangeline, by looking through windows and gaps, identifies the partial door codes. They communicate these codes to Harry, who then inputs them to clear Evangeline's path past the smoke monster.
