Wireless Room code: 13-05-36
Quick answer: set the three Wireless Room frequencies to 13, 05 and 36, in that order. Talk to all three brains first or the investigation may not be ready to validate the answer.
How to reach and solve the Wireless Room
- In Chapter 3, explore Akeley Hospital until you have the Old Man's Face Mask and can reach the east-side rooms above Reception.
- Pass the filing cabinets, move through the gap and enter the Wireless Room. Pick up the E.R.C. Activator Penbefore leaving.
- Speak to the jars containing Cornelius Wright, Ambrose Pence and Silas Dunwich. Their three testimonies join the Note About Wireless Room evidence group.
- Use the frequency machine and enter 13 → 05 → 36.
- Validate the sequence and take the Dream Essencefrom the device. This completes the investigation tied to The Whisperers achievement/trophy.
Video solution
If 13-05-36 does not work
- Confirm each brain has been spoken to until its dialogue is exhausted.
- Enter the middle value as 05, not 5 or 50.
- Check the Investigation screen for all three named testimonies and the Note About Wireless Room.
- If the device already paid out Dream Essence, the investigation is complete; check the achievement list instead of re-entering it.
