Safehouse Safe Code Solution

Changes Based on the Final Safehouse Puzzle Recording

During the mission The Rook: Arrival, you'll enter a KGB Safehouse in Bulgaria with a locked safe in its 2nd floor. The code used to open this Safe changes depending on the recording you get during the final Safehouse puzzle.

After further testing, the Game8 team confirmed that you cannot open the safe before solving all the puzzles even if you knew the correct code beforehand. However, once you do get your recording, you can use the phrases below to easily find your safe code:

How to Decipher the Recording

Use the Recording Keywords to Get the Code

Safe codes are unique to your playthrough and it will not be the same for every player. You will need to match the keywords that are mentioned during the recording to the items inside the radio room in order to figure out your own save's code for the safe.

All Safehouse Puzzle Solutions
1	Boiler Room Puzzle: Restore power to the safehouse's secret area by turning on the boiler room generator. Follow the steps below to solve the puzzle: ① Turn the Boiler valve 2 times until the meter reads 0 (until the leaking animation stops). ② Next, turn the Fuel valve 1 time until the meter reads 50. ③ Turn on the Pilot Light. ④ Fill up the Boiler by turning the Boiler valve 2 times again until the meter reads 100.
2	Piano Puzzle: Next, head to the piano room to open the entrance to the secret area. Sit down on the piano and play the following sequence to open the door: Mi > Re > Ti > Do > Re.
3	Keypad Puzzle: This one is a bit tricky since there is no set solution for it. Instead, here are some tips for solving the puzzle: ① Use the Blacklight to find the the buttons with the most presses. These are guaranteed to be part of the code so input them at least once when you start to decode the puzzle. ② Buttons with fewer presses may or may not be part of the code. Try them out and if they result in a red X, then they are confirmed to be not part of the code. ③ Buttons with lots of presses can appear in the sequence more than once. Those with fewer presses will only appear once. ④ It's okay to fail. You can attempt this puzzle multiple times but do note that the code changes each time you retry.
4	Hacking Puzzle: Inside the Mainframe Room, hack the terminal to open the door to the Interrogation Room. Match the Code Word numbers to the Cipher at the bottom of the screen to figure out the word. It will be either one of these 4 words: ① BUNKER ② OPEN ③ HOLDING ④ ROOM
5	Lockpick Puzzle: Inside the Interrogation Room will be a locked door leading into the torture chamber. Pick the lock to get the Key you need inside. The lockpick minigame is pretty easy. Rotate the pick until it starts shaking with a white outline. Hold it at this sweet spot to set the pin. Do this for the other 2 pins to open the door.
6	Radio Signal Puzzle: Finally, the Radio Signal puzzle is the only thing standing between you and the final Safehouse puzzle. Simply turn the Amplitude and Frequency knobs until the light beside each one turns green to solve the puzzle.
