- The Final Puzzle
Chairman’s Office Puzzle Box
To find the solution you need to pick up the Pencil from the backroom in Chairman’s Office, then in the main office use it on the piece of paper to shade in the words. This reveals the solution.
- Location: Care Center > West Wing (2nd Floor) > Chairman’s Office
- Solution: Moon – Sun – Star – Moon
Lead Researcher’s Office Puzzle Box
First, you must get the Corrosive from the Conference Room, at the end of the hallway outside Lead Researcher’s Office (where the big Chunk enemy comes from). Then you use the Corrosive on the padlock to melt it away. Afterward, look at the photos throughout the office, on the background you can see the correct symbols.
- Location: Care Center > East Wing (2nd Floor) > Lead Researcher’s Office
- Solution: Star – Sun – Moon – Sun
Organ Transport Box
After obtaining ID Wristband Level 1, you can use it in the corridor next to the kitchen to reach the Garage. You can open the Organ Transport Box immediately, but normally you’d get the solution from a file inside Lead Researcher’s Office Puzzle Box. You must inspect the Organ Transport Box from the inventory and press certain parts in specific order.
- Location: Care Center > West Wing (1st Floor) > Garage
- Solution: Examine the Organ Transport Box from inventory > turn it and click on the back panel > set bottom right switch to HAND > get the right switch to the middle level > press Button 5 > press Button 2 > set bottom right switch to AUTO again.

- Analyzer Blood Specimen (Converged) = Found in Closet (through Waiting Room Level 1 Door Lock). Click top middle square > click 2nd square from bottom.
- Analyzer Blood Specimen (Reversible) = Found in Blood Lab side room, behind the locked door that requires the ID Wristband to open. Click bottom-left corner square > middle square > top right square > second square from the topmost one.
- Analyzer Blood Specimen (Polymerized) = Exclusive to Insanity difficulty, found in in Closet (through Waiting Room Level 1 Door Lock), where the “Converged” variant was on Casual/Standard. Click middle left > middle right > middle bottom.
Security Manager’s Office Puzzle Box (Braille)
Despite being marked as a “Puzzle Box” on the map, it’s not really a puzzle – you just interact with the note on the table and interact with the Puzzle Box to get a cutscene. Afterward you grab the ID Wristband Level 3 from the table. Backtrack to Emily’s cell, through the safe room in Central Hall. Carry Emily to the Puzzle Box and she’ll open it automatically for you. Can clear out the zombies first by sitting Emily down on the couch in the safe room.
VIP Suite Double Helix Puzzle
In the VIP Suite you’ll find a lectern in front of the main desk with two helixes in it. You must interact with the wine bottle near the entrance, rotate it to reveal a Helix part inside. Insert it on the lectern. The other objects in the room are just distractions (the hourglass from the table isn’t used to solve it).
- Location: Care Center Courtyard > VIP Suite
- Solution: Open Wine Bottle to get Helix and insert it on the lectern.
Safe Codes

Pick up severed hand, take it to the analyzer, cryptic message says “let’s play”. Now if you run back to the puzzle in lead researchers office and input “Sun Sun Star Sun Moon Star Sun Moon Sun Moon Star Moon” there is a little kid that laughs. Trying to figure out the rest.
NL_the_Godfather says
Anything known about the final puzzle? You can get the severed hand spell the word GLITCH. Then find some letters that comes to this solution for the room with the sun moon star puzzle with the small notebook in the office.
Solution:

Sun moon sun
Moon star moon. Then you hear a laughter like the kids from the Orhpanage. But nothing is known after that part.

Ubllko1 says
“Sweet pair”… Chants of Leon and Claire?
MikeInfamous says
It says let the sweet pair hear the voice. There are two singing ladies in the area. Has anyone tried luring both to that area and then playing the noise?
MikeInfamous says
Or maybe if you bring Grace there and solve the puzzle that way. That could be the “sweet pair”

STEP 1 – Basement Water / Grinder Room
When you reach the basement area with:
The water
Falling bodies
The grinder mechanism
Do this:
Let 115 bodies fall into the water
Kill enemies normally.
Let their bodies drop into the water.
Keep count.
Do NOT leave early.
IMPORTANT CONDITION
When the grinder is ON:
Do NOT kill any zombies.
If you kill even one enemy while the grinder is active, you fail the hidden condition.
So:
Kill enemies while grinder is OFF
Survive / avoid killing while grinder is ON
STEP 2 – Drain the Water Properly
After the 115 body requirement:
Go down the pipe as normal.
Drain the water.
If you did everything correctly, you will see:
“A ton of blood has drained.”
If you DO NOT see that message, you failed somewhere:
Wrong body count
Killed during grinder phase
Missed the drain timing
STEP 3 – Continue Story Normally
Progress until you return to the upper areas.
