Resident Evil Requiem Final Puzzle Solution: Capcom Hates You

Capcom hid a 20,000 Challenge Point reward behind a puzzle so obtuse it took the dataminers to crack it, and no amount of logical thinking will get you there on your own.

The achievement description gives you exactly one line: "Let the sweet pair hear the voice." That's it. No hint system, no journal entry nudging you in the right direction, nothing. If you're chasing every achievement on our Resident Evil: Requiem Trophy Achievement Guide, this one's going to eat an entire evening, and you'll need two full playthroughs to finish it. Here's every step, in the order that actually works.

It Starts With a Conveyor Belt You're Not Supposed to Touch

During Grace's section in the Basement, you'll hit a room called Processing. There's a conveyor belt hauling hanging zombies toward a vat of blood, and your first instinct is going to be draining that pool and moving on with your life. Resist it. Just stand there and let the belt run for about 20 minutes.

The reasoning, if you can call it that, comes from a document titled "Subject 170" found in the Labs. It states The Girl was made from 524.3 liters of blood pulled from 115 infected subjects. So you're counting zombies. All 115 of them need to drop off that belt before you drain anything. Once the timer's up, pull the lever and jump down into the room below.

If speed is your thing, don't bring this puzzle anywhere near a timed run. Standing still for 20 minutes will torch your pace, so keep it out of any attempt you're logging for our Resident Evil: Requiem Speedrun Guide.

Feed the Belt, Don't Fight It

Dropping down activates the grinder, and the zombies on the belt start getting back up. The rule here is simple but unforgiving: you can't kill a single one yourself. Every body needs to go into the grinder on its own.

Grab a handgun and shoot legs, not heads. Leg shots stagger them long enough for the belt to carry them into the blades without you accidentally finishing the job. Pop a head off by mistake and the count's ruined, meaning a reload. When you finally pull the Collection Pool lever afterward, check the text prompt. "A torrent of blood" means you nailed the count. "A lot of blood" means something went wrong and you're doing it again.

The Severed Hand, the DNA Minigame, and a String of Letters

Once the count's locked in, keep pushing through the underground section until Grace gets to the elevator standoff with The Girl. The doors slam shut on The Girl's hand mid-escape, severing it. Walk back to the elevator afterward and pick the hand up off the floor.

You'll need to run this thing to a Laser Microscope, and there are two options: one in the Blood Lab in the East Wing, the other in the Upper West Wing Office. Scan the hand, work through the DNA minigame by turning the middle nodes red, and the game spits out a code once it's done: GGC AAG AUA ACG UGU CAU. Write it down. You'll need it much later.

The Toilet Flush That Broke the Internet

This is the step everyone's been talking about, and it's exactly as ridiculous as it sounds. Head to the Restroom in the West Wing, walk into the second cubicle, and flush the toilet eight times in a row.

There's no sound cue, no message, nothing confirming it worked. You just have to count and trust it. The only actual hint in the entire game is buried in the Investigation Report from the opening hour, showing a blurry photo of a corpse near a toilet with the number 8 smeared on the wall. It doesn't connect to anything else narratively. It just works, and figuring that out unprompted borders on impossible.

Marie's Doll Is Hiding in a Flooded Room

If the blood count and the toilet flush both landed, the game quietly sets up the next piece much later in the story. Push forward to the underground Research Lab where you're chasing the Helicopter Key. After the confrontation with Victor Gideon and the self destruct sequence kicks in, you'll end up in the Collection and Testing area, where a glass tank shatters and floods the room with blood.

Wade through it toward the stairs on the far side and check the floor by the bottom step. Marie's Doll is sitting there. Grab it, and the moment you find a storage box, drop it inside and leave it. Don't carry it around, don't lose track of it. Finish the campaign and let the credits roll.

New Game Plus and the Celestial Cipher

Start a New Game Plus off that cleared save, the one with the doll already sitting in storage. Somewhere in the Lead Researcher's Office is a Puzzle Box that takes Sun, Moon, and Star inputs, and translating the Severed Hand code into that symbol language means tracking down four separate clues scattered across the whole game.

• A sticker on the Blood Lab Microscope reads "G = 150000000," a reference to Earth's roughly 150 million kilometer distance from the Sun, so G becomes Sun.

• Flipping the hourglass in the VIP Suite reveals "U = 380,000," the rough distance in kilometers to the Moon, making U the Moon.

• Grace's Blood Analysis Report notes "C = 4.2 ly," the distance to the nearest star, so C becomes Star.

• Kicking the Toy Uncle head through the hoop on the Basketball Court with Leon tells you to "Just ignore A," meaning every A gets stripped from the code entirely.

Once you drop the A's, GGC AAG AUA ACG UGU CAU becomes GGC GUC GUG UCU. Translate that into symbols and you get the final input: Sun, Sun, Star, Sun, Moon, Star, Sun, Moon, Sun, Moon, Star, Moon. Twelve symbols, and getting even one wrong likely means starting the sequence over.

Bringing It All Together

Play through New Game Plus until you've picked up the Security Level 3 Keycard and rescued Emily. Take her to the Guard Room, pull Marie's Doll back out of storage, and keep it in your active inventory rather than tucking it away again. Then physically carry Emily up to the second floor of the East Wing, to the Lead Researcher's Office where the Puzzle Box sits.

Input the full twelve-symbol sequence while holding Emily. Get it right and you'll hear a child laughing, the game's way of confirming the "Sweet Pair," Emily and the doll, finally heard the voice. The achievement pops along with 20,000 Challenge Points to spend on bonus gear.

Whether that's a fair trade for an evening lost to toilet counting and orbital math is a separate question entirely.
