| Puzzle | Area | Answer / Code | How to Solve |
|---|
| Metal Detector / Special Alloy Emblem | Prison — Security Corridor | Hawk Emblem + TG-01 | The detector blocks metal items. Scan the Hawk Emblem and feed in the TG-01 alloy at the 3-D Duplicator to print a non-metal copy that passes through. Opens the gate out of the prison. |
| Iron Maiden | Prison — Statue Room | Rusted Sword into the maiden | Take the Rusted Sword from the statue, rotate the central statue to face correctly, then thrust the sword into the hole. Yields the Piano Roll. |
| Pass Number | Training Facility — Control Room | 1126 | Aim the security camera at the red skeleton picture in the biology lab and zoom in to read the number. Enter it on the Preparation Room lock. |
| Umbrella Security Lock | Palace — Hall computer | NTC0394 | The password is printed on the back of the ID Card — examine the card to read it. |
| Weapon Display — freeing Steve | Palace — Screening Room | C and E | Taking the Gold Lugers locks Steve in the hidden room. Six pictured switches appear; select the matching pair C and E to release him. |
| Gold Lugers plaque | Palace — Secretary's Office | Place both Gold Lugers | Pure key-item puzzle. The Lugers are never usable as a weapon — no ammunition for them exists in the main game. |
| Auto-play Piano | Palace — Casino Lounge | Insert the Piano Roll | Not a play-the-notes puzzle — the piano plays itself. The tune trips a compartment holding the King Ant Object. |
| Family Portraits | Palace — Family Portrait Room | Succession order (7 presses) | Press: the woman → the man holding twin babies → the red-haired man with the teacup → the red-haired man with the plate → the man with the vase → the man with the candlestick → the large Alfred portrait. The clue is the Memo to the New Family Master. Reward: Earthenware Vase → Queen Ant Object. |
| Alfred's Office computer | Palace — Office | 1971 | Turn the antique music box in the room; it reveals the four digits one at a time. |
| Ant Object music boxes | Private Residence — bedrooms | Queen → Alexia, King + Plate → Alfred | The Queen Ant Object opens Alexia's music box and yields the Music Box Plate; the King Ant Object plus the plate makes Alfred's box play, opening the passage. |
| Silver Dragonfly | Private Residence — Play Room | Remove its wings | Examine the dragonfly and detach the wings, exactly as shown in the childhood film in the Palace screening room. The wingless body is the key. |
| Cargo Crane | Airport — Cargo Bay | Raise fully, move left, drop | Repositions the crate so you can climb to the Biohazard Card. |
| Tyrant Catapult | Transport Plane — Cargo Hold | Hit the switch (×2–3) | The second Tyrant fight cannot be won by damage. Lure it into place and launch the cargo crate to knock it out of the plane. |
| Coloured Drawers | Training Facility B1 — save room (Chris) | RED → GREEN → BLUE → BROWN | Riddle: lava burns the forest, flows into the sea, and forms the earth. The brown drawer holds the Luger Replica — the Battle Game Steve unlock. |
| Refrigerator Temperature | Training Facility B1 — Chemical Storage | 12.8°C (dial: 128) | Open with the Chemical Storage Key and set the temperature. Clement Σ only becomes stable at that temperature. Hint: the memorial plate in the model exhibition room. |
| Chemical Mixing | Training Facility B1 | Clement α + Clement Σ | Makes the Clement Mixture, an acid that dissolves the special alloy coating on the Eagle Plate to reveal the gold Halberd. |
| Oil Pressure / Bridge | Airport 2F — Waiting Room (Chris) | 3, 3, 5, empty, 3, 3, 5 | A 10-litre tank with 3 L and 5 L feeders (the 1 L gauge is broken) and an empty button. Target is exactly 7 L: 3+3 fills 6; the 5 only fits 4 more so 1 L stays stuck in the gauge; empty the tank; 3+3 makes 6; the 5-gauge then discharges its leftover 1 L → 7. |
| B.O.W. Parcel / Gas Mask | Antarctic B2 — B.O.W. Room | Bar Code Sticker + conveyor | Sticker the crate and run the conveyor. The room gasses and the compartment opens, giving the Gas Mask you need for the Mining Room. |
| Valve Lathe | Antarctic B1 — Tool Storeroom | Valve Handle → Octa Valve Handle | Run the 4-sided handle through the lathe to make the 8-sided one that fits the gas valve. It stays on the valve — Chris collects it from there later. |
| Tiger Statue Eyes | Antarctic — Art Room | Cut the power first, then take both jewels | Shut the power off at the High Voltage Room, push the statue onto the cracked floor tile, and take the Red and Blue jewels. With power on you get a hidden compartment instead. |
| Antarctic Music Boxes | Antarctic B4 — replica bedrooms | Red → Alexia, Blue + Plate → Alfred | Stop the music in Alexia's room and use the Red Jewel for a Music Box Plate; the Blue Jewel plus the plate opens Alfred's box, revealing the ladder to the Conference Room. |
| Symbol Drawer | Antarctic B6 — Alexia's Laboratory | AA → CROWN → HEART → SPADE | The hint speaks of twins (AA), the queen (crown), veneration (heart) and the soldier (spade). Then insert the Paper Weight to get Alfred's Ring. |
| Three Jewels | Antarctic — Main Hall mural | Alexander (green) + Alfred (blue) + Alexia (red) | Place all three in the mural at the top of the central staircase to open the way onward. |
| Crystal & Cannon | Antarctic B4 — Detention Center | Crush it under the falling weight | Turn the cannon handle to tip out the Crystal, place it under the slab and drop the weight to reveal the Security Card. |
| Gold Dragonfly | Antarctic — assembled | Dragonfly Object + 4 Wing Objects | Two wings are in the Mansion Courtyard, one in the Ant Farm and one in the T-Veronica Lab containment chamber. Opens the Reactor Core. |
| Self-Destruct Password | Antarctic — Control Room | VERONICA | Use the Security Card, then type the password given in the Security File from the Detention Center. |
