The Final Puzzle Walkthrough
| Final Puzzle Step-by-Step Walkthrough | |
|---|---|
| 1 | Find the Shadow Ghost's Severed Hand |
| 2 | Analyze the Hand with the Laser Microscope |
| 3 | Figure Out the Moon Puzzle Code (Optional) |
| 4 | Decode the Severed Hand's RNA Sequence |
| 5 | Use the Code in the Lead Researcher's Office |
Find the Shadow Ghost's Severed Hand
After you rescue Emily from the Care Center basement, the Shadow Ghost gets its arm severed during the elevator cutscene. To start the Final Puzzle, pick up the Severed Hand in front of the Elevator after you pick up Emily.
Once it's in your inventory, make a quick stop at the Guard Office in order to put Emily down. Skipping this step means you won't be able to fight off any zombies on your way to the Blood Lab.
Use the Laser Microscope to Analyze the Hand
Next, take the Severed Hand to the Blood Lab in Care Center 1F. Deposit it into the nearby laser microscope to analyze its blood. To solve it, press the central black square, then press the black squares on the extreme left and right of the 3D model.
Once solved, you'll be met with a black screen that says "Let's play. GGC-AAG-AUA-ACG-UGU-CAU". After triggering this screen, something changes on the map. If you backtrack to the Lead Researcher's Office, you'll notice that its sun puzzle is interactable again even after it was solved.
We can surmise that the code GGC-AAG-AUA-ACG-UGU-CAU could perhaps have something to do with the Moon puzzle symbols of the Sun, Moon, and Star. All we need to do is figure out how G, U, C, and A relate to the Sun, Moon, and Star symbols.
Figure Out the Sun Puzzle Alternate Code (Optional)
| Letter | Meaning | Clue Location |
|---|---|---|
| G | Sun | Blood Lab Care Center 1F |
| U | Moon | VIP Suite Care Center Courtyard Surface |
| C | Star | Private Lab Care Center Courtyard Facility |
| A | None | Gun Shop Kendo Raccoon City Center |
※ Click on a letter to jump to its clue explanation.
This next series of steps is optional since you can skip them and go straight to the solution. But, if you want to solve the puzzle organically, do note that you'll have to replay the main story since the Sun Puzzle code needs to be used at the Care Center while the clues to solve it appear as late as Raccoon City.
Check the Laser Microscope for the "G" Clue
The easiest clue to find will be for the letter G. Simply interact with the laser microcope in the Blood Lab that you used to analyze the Severed Hand and you should be able to see a taped piece of paper on the side of the microscope that says "G = 150000000."
To make sense of it, keep in mind that all letter clues we'll be finding pertain to the distance between the Earth and other celestial bodies. In this case, 150,000,000 km is the approximate distance between Earth and the Sun, which means G = Sun.
Check the Hourglass for the "U" Clue
The next clue you'll find will be for the letter U. After dropping off Emily at the Helicopter, head inside the VIP Suite in the Care Center Courtyard - Surface Level. Here, you'll find an Hourglass that has no apparent use aside from the fact that it can be picked up and stored.
What you have to do is examine it and remove the screws on either side of it to get rid of its base. Then, turn the now freed hourglass upside down so that sand starts falling down into its other head. Once enough sand has drained, tilt the hourglass slightly and you'll see a clue that says "U = 380,000."
Coincidentally, the distance between the Earth and Moon is estimated to be around 380,000 km, which means that U = Moon.
Check Grace's Blood Analysis for the "C" Clue
The third clue can be found in the Private Lab at the Care Center Courtyard - Facility Level. In this room, look for a file titled Grace Ashcroft Blood Analysis Report (should be on a desk next to a computer monitor). Pick it up and read it. At the end of the report, you'll see a clue for the letter C where it says "C = 4.2 ly."
Similar to the first 2 clues, 4.2 ly stands for 4.2 light years which is the distance between Earth and the nearest Star (that isn't the Sun). This means C = Star.
Solve the Doll Head Puzzle for the "A" Clue
To find the clue for the letter A, you'll need to reach the R.P.D. as Leon. As you exit the R.P.D. north, you'll come across the ruins of Gun Shop Kendo. Head inside the small building north of it to find a headless doll whose head appears at the nearby Basketball Court.
Now, you won't be able to directly interact with the head, but you can push it by bumping Leon into it. Using this clunky method, kick the head over to one of the collapsed basketball rings and push it through the hoop. If done correctly, a sound cue should play allowing you to inspect the hoop.
On inspection, you'll see the message "There's no time for playing around". Once you read this, head back to the headless doll in Gun Shop Kendo to see that you can now interact with it (unlike before). Inspect it to get the message "Just ignore A". This means, you can safely ignore A from the RNA sequence we got from the severed hand.
Decode the Severed Hand's Blood Analysis Sequence
Now that we've figured out what each letter means, let's decipher the Severed Hand's blood analysis code, GGC-AAG-AUA-ACG-UGU-CAU. First, remove the letter A. This leaves us with, GGC-GUC-GUG-UCU. Then, we translate each letter into its corresponding symbol:
| Code | Meaning |
|---|---|
| GGC | Sun, Sun, Star |
| GUC | Sun, Moon, Star |
| GUG | Sun, Moon, Sun |
| UCU | Moon, Star, Moon |
Use the Alternate Code in the Lead Researcher's Office
Unmute the video to hear the baby's laugh. |
|
| Code | Sun, Sun, Star > Sun, Moon, Star > Sun, Moon, Sun > Moon, Star, Moon |
|---|---|
With the code figured out, backtrack to the Lead Researcher's Office in Care Center 2F and head back to the Sun Puzzle where you got the Sun Quartz earlier in the game.
Input the codes in this order: Sun, Sun, Star > Sun, Moon, Star > Sun, Moon, Sun > Moon, Star, Moon. If done correctly, you should hear the sound of a baby laughing.
At the time of writing, this is the furthest we've gotten in the Final Puzzle's solution. Stay tuned as we update the guide once we learn more and let us know in the comments if you have any clue on the next steps to take in this challenge.

The Final Puzzle Potential Clues
Leatherbound Notebook Obtained from the Lead Researcher's Office
One of the few quest items that doesn't get a checkmark throughout the game is the Leatherbound Notebook that you obtain from the sun puzzle inside the Lead Researcher's Office (the same one you use for the Final Puzzle).
Given how it is similar to the Hourglass (which also wasn't used in any puzzle or during the main story), we can infer that maybe it also has a part to play in the solution of the Final Puzzle.
Roulette Wheel Numbers
Players have pointed out that spinning the Roulette Wheel in the Parlor of the Care Center always results in getting either 29, 15, or 7. However, this clue is not related to the Final Puzzle as it is instead used to get Antique Coins in its own standalone mini-game / puzzle.
The Doll in the Cell
The doll in the cell found opposite Emily's cell at the Care Center is seemingly unrelated to the final puzzle. The team tested possible interactions with the doll but no new prompts were observed.
Tests included checking on the doll before, during, and after examining the severed hand and hearing the baby laugh from the sun puzzle.
Shooting the doll, picking it up and examining it, throwing a molotov at it, as well as bringing Emily to the doll did not result in any new interactions during the puzzle solving process at the Care Center.
Can You Use the Doll in the Cell?
The Final Puzzle Challenge Rewards
20,000 Completion Points
Solving the Final Puzzle will net you a cool 20,000 Completion Points (CP). This is one of the few challenges that reward you with this much CP when completed. CP can be used to unlock special content such as additional weapons and even cheat modes like Infinite Ammo.

Anonymous about 2 hoursHello everyone. I've already written to the community, but I'll write to you as well. The numbers 29 are black, 15 are black, and 7 is red, which I assume represents the time on the clock face! There are two black hands (hour and minute) and one red hand (second). The roulette wheel is round, which also provides a reference for the time! The question is, is this the time on the console (and where should I go) or on the clock in the game?
