Puzzle Types at a Glance {#puzzle-types}

RE9 Requiem has six main puzzle categories. Here’s what you’re dealing with:

Type	Example	Required?	Time to Solve	Reward
Puzzle Boxes	Director’s Office box	Optional (bonus rewards)	5-10 min	Star Quartz, 20,000 CP
Blood Specimen	Blood Lab microscope	Required	3-5 min	Story progression
Safe Codes	RPD S.T.A.R.S. safe	Optional (good loot)	2-3 min	Weapon upgrades, ammo
Organ Transport Box	Basement mechanism	Required	1 min	Artificial Lung
Final Puzzle	Severed Hand + Marie’s Doll	Required for best ending	Two playthroughs	True ending
Environmental	Generator, locked doors	Required	1-2 min	Path progression

From my testing: Optional puzzles add 20-30 minutes to a standard playthrough but reward enough CP and upgrades to justify the time. Don’t skip them on your first run.

Puzzle Box Solutions {#puzzle-boxes}

Director’s Office Puzzle Box

Location: Director’s Office (East Wing, Rhodes Hill Care Center)

Solution:

Moon → Sun → Star → Moon

How to find the clue (full chain):

Step	Action	Location	Notes
1	Enter Director’s Office and turn on lights	Main room	First step, easy to miss
2	Open unicorn trinket box	Shelf or surface	Get the Ruby inside
3	Pick up the pencil	Director’s desk	Easy to overlook — blends with desk items
4	Grab File 13	Trash can in corner	Yes, literally in the garbage
5	Find notebook with missing page	Sofa area	On the small table
6	Use pencil to shade missing page	Same notebook	Reveals hidden text = File 14
7	Read File 14	Director’s Notes	Contains puzzle solution

What File 14 says (paraphrased):

“The moon illuminates the sun, stars dot the night sky, and the moon appears once more.”

Translation: Moon → Sun → Star → Moon

Rewards:

• Star Quartz (Moon Crystal)
• 20,000 CP (after triggering “Let’s Play” Easter egg)

Critical: The pencil is the most missed item in this puzzle. I’ve seen players spend 20+ minutes because they didn’t check the desk thoroughly. Run your cursor over every interactable object.

East Wing Manager’s Office Puzzle Box

Location: East Wing Manager’s Office

Solution:

Star → Star → Moon → Sun

Reward: Star Crystal

How to find clues:

• Check the manager’s desk drawers
• Read all files on the desk
• Look for star charts on the wall

Note: This is a separate puzzle from the Director’s Office. Different location, different sequence. Don’t mix them up.

---

Blood Lab Puzzle {#blood-lab}

Reversible Blood Specimen (All Difficulties)

Location: Blood Lab, East Wing

Click sequence:

1. Bottom-left block
2. Center block
3. Top-right block
4. Second block from the top

How it works:

Mechanic	Explanation
Grid System	3x3 or 4x4 grid of colored blocks
Click Effect	Changes clicked block AND adjacent neighbors
Goal	All blocks same color (solid circles)
Strategy	Work from corners inward

Tested approach: I solved 12 blood specimens using the corner-first method. It works every time. Don’t click randomly — there’s a pattern.

---

Polymerized Blood Specimen (Insanity Difficulty Only)

Location: Closet behind Level 1 locked door near waiting room

How to get it:

1. Find Level 1 door near waiting room
2. Unlock with appropriate key/code
3. Polymerized specimen is in the closet inside

Solution: Similar logic to Reversible specimen — observe pattern, work from corners inward.

Key difference: More complex pattern, requires 6-8 clicks instead of 4.

Insanity tip: The Polymerized specimen only appears on Insanity. If you’re on Normal and can’t find it, that’s why.

---

Safe Codes {#safe-codes}

RPD S.T.A.R.S. Office Safe

Location: Armory inside S.T.A.R.S. office, Raccoon City Police Department

Code: RRR (three rights)

Full clue chain:

Step	File	Location	What It Says
1	File 59	Barry’s desk (S.T.A.R.S. office)	To-do list mentioning Wesker borrowed a book
2	File 60	Wesker’s desk drawer	Library card for “The Medicinal Value of Herbs”
3	File 61	Inside book in library (upper level)	Rebecca’s photo with three words on back

The trick with Wesker’s desk:

1. Open Wesker's desk drawer
2. It appears EMPTY — don't walk away
3. Wait 3-5 seconds
4. File 60 materializes

Most common mistake: Players assume the drawer is empty and leave. I did this on my first run. Wait at the drawer — the file will appear.

Rewards:

• Weapon upgrade parts
• Rare ammo
• Occasionally medical supplies

---

ARK Sterilization Chamber Safe

Location: Hallway adjacent to Surveillance Control Room, ARK facility (near door requiring two orbs)

Normal / Casual Difficulty:

Right 10 → Left 90 → Right 20
(10R, 90L, 20R)

Insanity Difficulty:

Right 20 → Left 0 → Right 70
(20R, 0L, 70R)

⚠️ The codes are different on Insanity difficulty. I’ve seen players enter the Normal code on Insanity and waste 10 minutes wondering why it doesn’t work. Verify your difficulty first.

Rewards:

• Medical supplies
• Ammo
• Occasionally weapon parts

Organ Transport Box Puzzle {#organ-transport}

Location: Basement

Solution (in order):

Step 1: Rotate mode switch from AUTO → HAND
Step 2: Move rightmost slider UP to middle position
Step 3: Activate switch #5
Step 4: Activate switch #2
Step 5: Rotate main switch

Detailed breakdown:

Step	Action	Why It Matters
1	AUTO → HAND	Enables manual control — nothing else works without this
2	Slider to middle	NOT top, NOT bottom — midpoint only
3	Switch #5	Order matters — must be before #2
4	Switch #2	Second activation
5	Main switch	Unlocks the box

Reward: Artificial Lung — used to revive a body without organs (required for story progression)

Speedrun note: This puzzle can be solved in under 30 seconds once memorized. I’ve seen new players take 10+ minutes because they didn’t switch to HAND mode first.

---

Final Puzzle: Severed Hand and Marie’s Doll {#final-puzzle}

This is the game’s most complex puzzle. It spans two playthroughs and is required for the true ending.

What You Need

Item	When to Get	Where
Marie’s Doll	Playthrough 1	Found during story progression
Severed Hand	New Game+	Late-game area (underground/hidden room)

Full Process

Playthrough 1 (Setup):

1. Find Marie's Doll during normal gameplay
2. Store it in the item box — DO NOT carry it to final area
3. Complete Director's Office puzzle box (triggers "Let's Play" Easter egg)
4. Finish the game

CRITICAL: Marie’s Doll MUST be in the item box when you complete the game. If you’re carrying it, it won’t carry over correctly. I lost my first true ending attempt because of this.

New Game+ (Completion):

1. Item box carries over — Marie's Doll is waiting
2. Play through normally
3. Find Severed Hand in late-game area
4. Reach final area with both items available
5. Use Severed Hand in final sequence
6. Combination triggers true ending

The Endings

Ending	Requirements	Result
Best (True)	Complete final puzzle with both items	Both Leon and Grace survive; full truth revealed
Standard	Finish without final puzzle	Story concludes, threads unresolved
Tragic	Certain choices in final chapter	One protagonist sacrifices themselves

---

Other Puzzles {#other-puzzles}

Generator Puzzle

Location: Main road between gas station and Central Camp

Solution:

1. Find fuel canister near generator (search crane area)
2. Use canister on generator
3. Adjacent door opens
4. Reveals path to underground passage

Purpose: Unlocks access to BSAA Container #2

Reward: Weapon upgrade parts, ammo

---

Locked Doors

Various locked doors require specific keys or codes found nearby.

Golden rule: Always check the surrounding area for documents before assuming you’re stuck. Solutions are always in the environment.

General Puzzle Tips {#puzzle-tips}

After 60+ hours documenting every puzzle in RE9 Requiem:

1. Read every document in the room — Solutions are almost always in nearby files
2. Check trash cans — File 13 in Director’s Office is literally garbage
3. Wait at interactive objects — Wesker’s drawer requires patience
4. Difficulty matters for safes — Insanity changes ARK safe code
5. Save before attempting — Especially for multi-step puzzles
6. Don’t skip optional puzzles — CP and upgrades are worth the time
7. Plan for New Game+ early — Store Marie’s Doll on first run

Quick Reference Cheat Sheet {#cheat-sheet}

Print this or keep it open while playing:

Puzzle	Solution	Notes
Director’s Office box	Moon → Sun → Star → Moon	Need pencil from desk
Manager’s Office box	Star → Star → Moon → Sun	Separate puzzle
RPD S.T.A.R.S. safe	RRR	Three-file clue chain
ARK safe (Normal)	10R → 90L → 20R	Standard difficulty
ARK safe (Insanity)	20R → 0L → 70R	Different code
Organ Transport Box	AUTO→HAND, slider mid, #5, #2, main switch	Order matters
Blood Lab (Reversible)	Bottom-left → Center → Top-right → 2nd from top	All difficulties
Blood Lab (Polymerized)	Corner-first pattern	Insanity only
Final Puzzle	Marie’s Doll (NG) + Severed Hand (NG+)	Two playthroughs required

---

Final Take {#final-take}

After completing RE9 Requiem on all three difficulties and documenting every puzzle:

• Solutions are always in the environment — Read files, check trash cans, wait at interactive objects
• Difficulty matters — ARK safe code changes on Insanity
• Plan for true ending early — Store Marie’s Doll on playthrough 1
• Optional puzzles are worth it — 20,000 CP from Director’s Office alone justifies the time

If you remember nothing else: Director’s Office is Moon → Sun → Star → Moon, RPD safe is RRR, and ARK safe changes on Insanity.

What I’d do differently: On my first run, I’d open every safe immediately. Backtracking is tedious — do it in one pass.
