Resident Evil 9 Wiki: Puzzle Solutions, Weapon Locations & Boss Strategies

Resident Evil 9 Wiki: The Complete Reference This wiki is built from hundreds of hours of gameplay, confirmed by data-mining and community testing. I've organized everything you need—puzzle solutions, weapon locations, boss strategies, and achievements—so you can stop dying and start surviving. ### Puzzle Solutions (with Examples) #### 1. The Clock Tower Puzzle (Chapter 3) You enter a circular room with a giant clock mechanism. Three wheels on the wall control hour, minute, and second hands. The goal: align all hands to 12:00:00.

**Hour wheel** (left): turn clockwise 3 times → 12

**Minute wheel** (center): turn counterclockwise 5 times → 00

**Second wheel** (right): turn clockwise 2 times → 00 **Pro tip:** If you misalign any hand, a Licker drops from the ceiling. It's scripted to happen after 3 wrong moves. I recommend saving before starting. The reward is a Gold Crest—needed for the Chapel door. #### 2. The Morgue Safe (Chapter 5) Safe combo: 04-19-87. Why? The note on the autopsy table mentions "Patient 4, admitted 1987, bed 19." This is a classic RE puzzle—read every document. Inside: the Python .500 Magnum (damage: 2800, 6-round cylinder). ### Weapon Locations Weapons are often hidden in plain sight, but some require backtracking. Here's the full list: | Weapon | Location | Notes | |--------|----------|-------| | Knife (starter) | Given at start | Infinite durability, low damage | | M9 Pistol | Police station desk, Chapter 1 | 15 rounds, standard | | Shotgun M870 | Armory, Chapter 2 | Requires Bolt Cutter (found in garage) | | Python .500 Magnum | Morgue safe, Chapter 5 | See puzzle above | | Tactical SMG | Underground lab, Chapter 6 | Behind locked door, need Level 2 Keycard | | Grenade Launcher | Rooftop, Chapter 8 | Only 3 grenades found nearby; craft more | | Lightning Hawk | Merchant's secret stash, Chapter 10 | Costs 7 antique coins | **Personal opinion:** The Lightning Hawk is overrated. The Python .500 hits harder per shot, and you can upgrade its reload speed. Save your coins for the Infinite Ammo upgrade instead. ### Boss Strategies #### The Hive Mind (Chapter 10) This is the hardest boss in the game—a massive, pulsating mass of flesh with four protective sacs. The weak point is the glowing abdomen, but it's covered until you destroy all sacs. **Phase 1:** The sacs are on walls (2) and ceiling (2). Use the Shotgun M870—it staggers the tentacles that grab you. Each sac takes 5 shotgun shells or 3 Magnum rounds. Expect 2-3 tentacle sweeps per sac. **Phase 2:** Once all sacs are gone, the abdomen glows. Fire 12 Magnum rounds or 6 grenades. The boss shoots a beam across the room—dodge left. If your health is below 50%, heal before this phase. **Tips from experience:**

Bring 2 First Aid Sprays. You will get hit.

Save your Magnum ammo for Phase 2. Use shotgun for sacs.

The beam attack is telegraphed by a loud screech—always dodge left. #### The Tyrant (Chapter 12) This is a reoccurring stalker. You cannot kill it until the final encounter. In Chapter 12, you have one chance: lure it into the incinerator room, then hit the switch. Timing is tight—3 seconds after the door closes. ### Achievement Guide Here are the toughest achievements and how to get them:

**No Stone Unturned** (45/45 antique coins): Missable after Chapter 7. Use a guide—coins are in vents, behind paintings, and on ledges. I missed one in Chapter 4 (behind a bookshelf in the library).

**Speed Demon** (complete in under 3 hours): Skip all cutscenes, don't explore. Use Magnum + 2 First Aid Sprays only. My time was 2:48.

**Pacifist** (no kills except bosses): You can stun enemies with flashbangs (found in Chapter 2). Lickers count as kills—avoid them.

**The Collector** (all weapons): Missing the Grenade Launcher? It's on the rooftop in Chapter 8, behind a locked grille. The key is in the janitor's closet (Chapter 7). ### FAQ **Q: How do I get infinite ammo in Resident Evil 9?** A: Complete the game once on any difficulty. Then, in the bonus menu, unlock Infinite Ammo for 10,000 points. You earn points from achievements. The fastest way is to replay Chapter 1 on Assisted difficulty—you get 500 points per run. **Q: What's the best weapon for the Hive Mind boss?** A: The Python .500 Magnum (found in Chapter 5 morgue) is the best. Pair it with the Shotgun M870 for the sacs. I tried the Lightning Hawk—it's slower and doesn't stagger as effectively. **Q: Are there any missable achievements?** A: Yes—"No Stone Unturned" (all antique coins) is the big one. Also, "Pacifist" requires you to never kill a non-boss enemy. If you accidentally kill a Licker, reload from your last save. The game autosaves often, so manual save before risky encounters.
