Disclaimer: The “Rooftop One Percent” DLC is required!
If you have a look on the desk, you can see a periodic table with the Gold element circled and a +, a sheet about the Fibonacci sequence next to it, and a phone. This gives you a first hint for what you’ll need for this ARG.
Note: If you want to know more about the available phone numbers, check this page.
Do the Math
Once you’ve got the Gold Duck from the base game in the pool, name it “Fibonacci”. A five-digit code appears over its head that is different for every player. If you now add the Fibonacci sequence (1-1-2-3-5) to the number (for example: your code is 04400, so 04400+11235=15635), you receive a new code.
Note: You can do this step in any map to cut down waiting time and then return to Rooftop One Percent for the rest. This is also possible without owning the DLC.
Now turn to the phone. On the top right is a hint on how to use the phone: you type in a number and press the green button to dial it up. Enter the code with the Fibonacci-addition and press the green button. If your math is right you will hear a fanfare.
If you look next to the elevator, you can now click on the buttons. Click the button that calls the elevator to go down.
The Lockbox Room
Epilepsy/Photosensitivity warning! The upcoming part contains flickering lights!
You find yourself in a room with safelock boxes with four-digit numbers and a wall of 31 keys. If you remember the date of the missing duck flyer of the Milk Duck, you know what you need to look out for.
Pick up the 17th key and look for the lockbox with the number 2022. Insert the 17th key on the left side of the lockbox.
Note: If you happen to insert the key into a wrong keyhole, you can either switch it out with a second key to have the first key reappear on the board, or you can leave the room and come back in to reset it.
Pick up the 8th key and insert it into the right side of the 2022 lockbox. The lockbox now opens and reveals a new tangerine-flavoured soda can! Upon pickup, the forsaken folder appears and shows a new file: P-um.fbx
The Reward!
You can now leave the lockbox room via the elevator call buttons.
The seating area on the bottom outside pool now sports the newly acquired soda can and a picture of a group with distorted faces and seven red crosses on the bottom right.
