The Final Puzzle is a challenge in Resident Evil Requiem. The challenge says “Let the sweet pair hear the voice“. This refers to Emily and Marie’s Doll having to hear the laughing girl in Lead Researcher’s Office. This challenge is entirely optional and isn’t required for any trophies/achievements. It unlocks 20,000 CP extra which can be spent on bonus items.
This puzzle takes place across 2 playthroughs. You can’t complete the steps in a single playthrough. On one playthrough you must get Marie’s doll. Then complete the game with it in your inventory and you will have it permanently for the second playthrough. Then you must enter a combination in the Lead Researcher’s Office Puzzle Box while carrying Emily and having Marie’s Doll in your inventory (after escaping basement). This will finish the puzzle. All steps are done as Grace.
Here’s a step by step guide to solve the final puzzle:
Step 1: Let 115 Bodies drop into the water in “Processing” room of Care Center Basement
In Care Center Basement, after using the Forklift Key to raise the Forklift in the Furnace area, you will go through an area with body bags on conveyor belts. When you reach the end of the moving body bags, you will be in the room titled “Processing“. DON’T interact with the valve yet that drains the water (the one next to a typewriter save). WAIT here and let 115 bodies fall from the conveyor belt into the bloodied water. Be patient and keep count. DON’T leave this area. It will take around 15 minutes real time. It’s the room with the grinder mechanism and a typewriter.
After 115 bodies fell into the water use the valve to drain the water.
Step 2: Finish Grinder Section WITHOUT killing any zombies yourself
In the same room, after interacting with the valve to drain the water, climb down the ladder and the grinder will activate. Let all of the zombies get killed by the grinder. DON’T kill any zombies yourself. Killing any yourself will fail this step.
Step 3: Drain the bloodied water
After the grinder section and grabbing the third Joint Plug, climb back up to the typewriter and go through the vent. You will slide down into a pool of bloodied water. Flip the switch on the wall (before going up elevator) and look at the drained blood pool. You will get the text subtitle at the bottom of the screen “A ton of blood flowed out“. If you get a different subtitle you messed up and must redo the first two steps (wrong body count, killed a zombie in grinder).
Step 4: Flush a Toilet 8 Times with Emily in Restroom
Proceed with the story until Grace escapes the basement with Emily through the elevator and you’re back in the Care Center’s Central Hall. Carry Emily with you to the Restroom in West Wing (accessed from corridor between Kitchen and Dining Room). Flush any toilet in the Restroom 8 times total. Flush the SAME toilet EXACTLY 8 times in a row, not 7 and not 9. There won’t be a confirmation popup or anything.
Step 5: Get Marie’s Doll in Collection & Testing Room
Proceed the story until you went through the Care Center Courtyard (outside), went through the VIP Suite, went through the underground base and found the helicopter keys. The underground base will then start to explode and you are supposed to run back out to the helicopter. Go through the room titled “Collection & Testing” on the map, where a bunch of zombies will attack you. After passing through this area, you enter the backside of the room and the big blood tank in the middle will burst and flood the area with blood. The entire floor will now be filled with a pool of blood. Immediately after the blood tank bursts, you can find the Marie’s Doll on the left side of the area in the blood on the ground. Directly at the metallic stairs that lead out of the room. Be sure to pick up the doll here!
KEEP MARIE’S DOLL IN YOUR INVENTORY AND FINISH THIS PLAYTHROUGH BY RELEASING ELPIS. DON’T DISCARD THE DOLL.
Step 6: Start Second Playthrough
Start a new playthrough, Marie’s doll will carry over.
Step 7: Enter secret code into Lead Researcher’s Office while carrying Emily + Marie’s Doll
Advance story until you exit the Care Center basement where you carry Emily around with you. (After “The Girl” monster’s hand gets severed during elevator ride)
Go to Lead Researcher’s Office puzzle box, in Care Center East Wing, 2nd floor.
Enter this code WHILE HAVING MARIE’S DOLL IN INVENTORY + CARRYING EMILY WITH YOU:
- Sun
- Sun
- Star
- Sun
- Moon
- Star
- Sun
- Moon
- Sun
- Moon
- Star
- Moon
–> A girl will laugh, which is the “voice” you must hear. The “sweet pair” is Marie’s Doll + Emily. If you complete this while holding both Marie’s Doll + Emily you will get a popup that the Final Puzzle has been solved.
“Congratulations!”
“You let the sweet pair hear the voice.”
