Resident Evil Requiem: How to Solve the Final Puzzle – 20,000 CP

Why This Final Puzzle Is So Easy to Miss

After finishing Resident Evil Requiem the first time, I spent way too long staring at the Challenges screen, wondering what “O Enigma Final” even meant. All it gives you is a vague hint like “Make the pair of angels hear the voice” and a promise of 20,000 CP. No markers, no quest log, nothing.

The breakthrough came when I stopped trying to brute-force the angel console and instead retraced every unresolved “that was weird” moment in the campaign: the Meat Processing room, the grinder, the creepy toilets, the lab blood orb, the severed hand, and the Marie doll references. Once the community pieced it together in March 2026, I went back and tested the full chain on my own saves to make sure it actually works.

This guide walks you through the exact steps I used to unlock the Final Puzzle challenge and claim the 20,000 CP, including where the game quietly fails your attempt if you do something wrong. Follow this in order and you won’t have to replay more than necessary.

Quick Overview & Requirements

Before diving into the details, here’s what you’re committing to:

• Two playthroughs required: One to set up and secure the Marie doll, another to actually input the code.
• Platform: Works on PC, PlayStation and Xbox (I tested on PC and PS5).
• Reward: 20,000 CP + a secret device activation in the East Wing of Rhodes Hill.
• Time investment: Around 15-20 minutes of extra “puzzle time” per run, on top of your regular gameplay.

Most failed attempts come from one of these four things:

• Killing zombies in the grinder section with weapons or explosives.
• Not waiting the full 15 minutes in the Meat Processing room.
• Pulling the wrong toilet chain or miscounting the eight flushes.
• Starting a new run without finishing the first game with the Marie doll stored properly.

Everything else is mostly flavor and lore. The core of the puzzle is strict, but consistent once you know the rules.

Part 1 – How to Get the Marie Doll (First Playthrough)

This first part is all about setting a hidden flag so the Marie doll can spawn later in the underground lab. If the doll never appears, the Final Puzzle cannot be completed on that save.

Step 1 – Wait 15 Minutes in the Meat Processing Room

In Rhodes Hill’s basement, you’ll reach the Meat Processing room, the one with the hanging corpses and the big grinder/sluice setup. Normally you just crank the wheel, dump the blood and move on. For the Final Puzzle, you must do the opposite.

• Enter the Meat Processing room as usual.
• Do not touch the wheel that releases the blood.
• Stay inside the room for a full 15 minutes of real time.

On my first attempt I thought 10 minutes would be “close enough.” It wasn’t. The game is strict here. On PC I literally set a phone timer for 15:30 to be safe, walked around the room a bit, checked items, but never interacted with the wheel or left the room.

You won’t get an obvious confirmation. No cutscene, no sound cue. Just trust the timer. Once the 15 minutes are up, then you can move to the next step.

Step 2 – Use Only the Grinder to Deal with Zombies

After you finally crank the wheel, the blood pours down and zombies start spilling onto the conveyor. This section is where it’s easiest to fail the puzzle without realizing.

• Let the blood flow as normal by turning the wheel.
• When zombies appear, do not shoot, stab or burn them.
• Instead, kite and shove them into the grinder, or let the conveyor pull them in.

The idea is that every zombie in this sequence must die via the grinder, not by your weapons. I made the mistake of panicking and tossing a molotov once; that invalidated the flag and the doll never appeared later in that run.

If you’re nervous, unequip your gun and knife so you don’t accidentally lash out. The grinder does the job if you position yourself so zombies walk straight into it.

Step 3 – Flush the West Wing Toilet Eight Times

Next, play on until you’re back at the Rhodes Hill Care Center. You’re looking for the West Wing bathroom near the kitchen.

• Go to the West Wing corridor that leads to the kitchen.
• Enter the bathroom on that corridor.
• In the row of stalls, interact with the second cubicle from the left (this is the one that worked consistently for me).
• Pull the flush chain exactly eight times in a row.

The game doesn’t pop up a message here either. You’ll just hear the repeated flushing. Count out loud if you have to. Don’t leave the stall between pulls; just interact-eight-times, then move on.

Some early reports mention other stalls, but in my testing the second cubicle was the reliable one. If you’re following this guide, stick to that to avoid headaches.

Step 4 – Trigger the Blood Orb and Collect the Marie Doll

Now just progress the story normally until you reach Victor Gideon’s lab in the underground section. You’ll eventually hit the scene where the giant blood orb overloads and explodes, covering the area with “a ton of blood” (“um montón de sangue” as the community jokes).

• Play the lab segment until the blood orb bursts.
• As you flee upwards, keep an eye at the foot of the staircase right after the explosion.
• If you did everything right so far, a Marie doll will be lying on the ground.
• Pick it up immediately.

On the run where I messed up the grinder rule, this doll simply never spawned. On the successful run, it was unmistakable: a creepy little doll sitting in the blood at the bottom of the stairs.

Step 5 – Finish the Game with the Doll in the Item Box

Once you have the Marie doll, the last thing you need to do in this first playthrough is finish the game with the doll safely stored.

• Drop the Marie doll into any item box (storage chest).
• Do not sell or discard it.
• Complete the story and roll credits with the doll still in storage.

I put the doll away as soon as I reached a box and never touched it again for the rest of the run. When you load this clear save later, the game remembers that you completed it with the doll in your possession, which is crucial for the next part.

Part 2 – Making the Angels Hear the Voice (Second Playthrough)

With the Marie doll flagged on a completed save, you’re ready to actually solve “O Enigma Final.” This all happens on a new playthrough, not via chapter select.

Part 2 – Making the Angels Hear the Voice (Second Playthrough)

With the Marie doll flagged on a completed save, you’re ready to actually solve “O Enigma Final.” This all happens on a new playthrough, not via chapter select.

Step 1 – Start a New Campaign from Your Clear Save

From the main menu, load the file where you finished the game with the Marie doll in your item box, then start a new run from there (New Game or New Game+ depending on what the game offers for that save).

Play normally until you reach the point where you rescue Emily and can carry her in your arms. This is your main condition for the final input: the code must be entered while physically holding Emily, not when she’s walking by herself.

Step 2 – (Optional but Recommended) Scan the Severed Hand

This step isn’t mechanically required if you already know the code from a guide, but it’s where the puzzle’s internal logic lives, and it’s how the community got from “GLITCH” to the Sun–Moon–Star sequence.

• In this new run, reach the section with the severed hand (usually labeled something like “Severed Hand” in your inventory).
• Make sure you have access to the blood scanner / laser microscope device.
• Use the scanner on the hand to reveal a coded sequence resembling DNA/RNA with the marker word “GLITCH”.

By mapping the GLITCH markers to astronomical symbols (Sun, Moon, Star), the community derived the 12-step pattern we’ll enter later. You don’t have to solve that yourself now, but if you like Resident Evil lore puzzles, it’s worth seeing once.

Step 3 – Go to the Chief Researcher’s Office with Emily in Your Arms

After rescuing Emily, before pushing too far along the critical path, detour to the Chief Researcher’s Office. This is the same room you previously opened using acid during the main story puzzle.

• Carry Emily (don’t set her down).
• Navigate back to the Chief Researcher’s Office.
• Inside, locate the angel console with the Sun/Moon/Star symbols.

Important condition checks at this point:

• You must be holding Emily.
• Your save must be descended from a clear file that finished with the Marie doll in storage.
• To be extra safe, I also kept the Marie doll in my inventory during this run once I could access the item box, since several players reported better consistency that way.

If all that is true, the console is ready to accept the secret sequence.

Step 4 – Input the 12-Symbol Sun/Moon/Star Code

Interact with the angel console. You’ll see three symbols you can cycle or press in sequence: Sun, Moon, and Star. The puzzle solution the community verified (and that I used successfully) is this 12-step pattern:

Sun, Sun, Star, Sun, Moon, Star, Sun, Moon, Sun, Moon, Star, Sun

Earlier guides sometimes listed the final symbol as Moon, but on my tests with the most recent patch, the sequence only completed when I ended on Sun. If you follow the pattern above exactly, you should be fine.

• Stand at the console with Emily in your arms.
• Enter the symbols one by one in this order, taking your time.
• Do not back out of the interface halfway through; if you make a mistake, cancel completely and start again from the first Sun.

When you hit the final Sun, you’ll hear a distinct child’s laugh (“risada de criança”) and the angels “react” as if they’ve heard a voice. That audio cue is your confirmation that the puzzle has triggered correctly.

Step 5 – Claim Your 20,000 CP Reward

Once the laugh plays, the game silently marks the Final Puzzle challenge as complete.

• Finish your current segment or continue to any convenient save point.
• From the main menu, open Extras → Challenges (or your platform’s equivalent).
• You should now see that “O Enigma Final” is marked as cleared, with a reward of 20,000 CP already added to your total.

On my run, the CP bumped instantly, just like any other completed challenge. In addition, a secret machine in the Rhodes Hill East Wing becomes usable, tying back into the lore behind the Marie doll and Emily.

Common Problems and How to Fix Them

Because this puzzle chains actions across two playthroughs, it’s easy for something tiny to break the sequence. Here are the issues I ran into and how I solved them.

The Marie Doll Didn’t Spawn in the Lab

• Check the Meat Processing wait: If you didn’t stay in the room for a full 15 real-time minutes before touching the wheel, the flag won’t set.
• Review your kills: If you used any weapon, knife, or molotov on zombies during the grinder sequence, that run is bricked for the puzzle.
• Toilet stall and counts: Make sure you used the West Wing bathroom near the kitchen, second stall from the left, exactly eight flushes.

If any of those might be wrong, you’ll have to reload a save before the Meat Processing room and redo all the steps. In my failed run, no amount of backtracking after the fact could “rescue” the doll spawn.

I Entered the Code but Didn’t Hear the Child’s Laugh

• Verify you were holding Emily at the console, not after setting her down.
• Confirm you’re playing on a file that completed the game with the Marie doll in the item box.
• Try entering the exact sequence again: Sun, Sun, Star, Sun, Moon, Star, Sun, Moon, Sun, Moon, Star, Sun.
• Double-check that you didn’t accidentally back out or misinput midway-if in doubt, cancel fully and restart the sequence from scratch.

In one of my attempts I realized I’d forgotten to ever retrieve the Marie doll from storage in the second run. After grabbing it from the item box and keeping it in my inventory, the sequence worked on the next try.

Wrapping Up – Why the Puzzle Feels So Cryptic

Even after solving it, the logic behind “O Enigma Final” is intentionally opaque. The GLITCH markers, the astronomical symbols, the grinder-only kills, the toilet chain, the blood orb and the Marie doll all tie into themes of sacrifice and voices carried through blood, but the game never spells it out.

From a practical standpoint, though, you don’t need to decode all that yourself. If you:

• Wait 15 minutes in the Meat Processing room without touching the wheel,
• Use only the grinder to kill those zombies,
• Flush the correct West Wing toilet eight times,
• Grab the Marie doll after the lab blood orb and finish the game with it stored,
• Then, on a new run, carry Emily into the Chief Researcher’s Office and input the 12-symbol Sun/Moon/Star code,

you’ll reliably trigger the child’s laugh, complete the Final Puzzle challenge, and pocket your 20,000 CP like I did.

If this puzzle drove you as crazy as it did me, at least now you only have to suffer through it once. From here on out, that CP can go straight into the fun stuff-bonus weapons, costumes, and whatever else you’ve been eyeing in Requiem’s extra content.
