Essential Secret Mechanics
Before diving into the level-specific guides, it is important to understand how secrets are categorized in the 2026 version of the game.
- Secret Locations: Usually hidden rooms or compartments that contain large sums of cash or unique items like the Katana.
- Cassette Tapes: Found in both Normal and Nightmare modes, these unlock new tracks for your music player.
- Music Disks (Nightmare Mode): Exclusive to Nightmare Mode, these require specific puzzles to be solved and replace standard secrets.
- Evidence: While not always "secrets," some pieces of evidence are hidden behind secret doors and are required for a perfect score.
💡 Tip: Use your "Cleaner Sense" (V key by default) frequently. It often highlights interactable objects like loose floorboards or tilted wall sconces that lead to secret areas.
Bad Call: Secrets & Collectibles
The first mission introduces you to the verticality of the game's secrets. You will need to explore both the interior apartments and the exterior ledges.
| Secret Type | Location | Requirement |
|---|---|---|
| Secret 1: Botanical Room | Deep courtyard behind an iron door | Find two keys (one on a box, one in a bathroom) |
| Secret 2: Room Below Lift | Floor below the dealer's apartment | Walk along the exterior ledge from the balcony |
| Secret 3: Rooftop Den | Roof of the adjacent building | Break wooden boards blocking a hallway window |
| Cassette: Cieszyn's Venice | Inside the Botanical Room | Unlock the second door within the secret room |
Nightmare Mode: The Polaroid Quest
In Nightmare Mode, the music disk is locked in a darkroom. You must find the Polaroid Camera in the attic and take four specific photos:
- The Attic: Behind the overgrowth in the back room.
- The Ledge: Outside the hallway window where the Normal Mode secret is located.
- The Yard: Near the dumpsters.
- The Downstairs Apartment: Accessed by breaking wooden slats.
Trial By Blood: The Spa Secrets
This level relies heavily on a chain of keycards. To find crime scene cleaner all secrets here, you must be methodical with your looting.
- Locker M034: Find the keycard on the tanning room table.
- VIP Card: Open locker M034 in the Men's Locker Room to find the VIP card.
- The VIP Room: Use the VIP card on the controller in the digital lock room (opposite the locker room). This opens a hidden wall in the pool area.
- Locker W018: Take the W018 card from the VIP room coffee table and use it in the Women's Restroom.
⚠️ Warning: The digital lock room requires a hacking mini-game. Time your clicks carefully when the moving line aligns with the highlighted numbers.
Toxic Love: The Hidden Painting
This mission is relatively compact, but the secrets are tucked away behind the villa's decor.
- The Main Secret: In the living room, look for a vertical painting framed between two lamps. Interact with it to reveal a hidden compartment.
- Secondary Switch: Inside the first secret compartment, there is another painting near the fuse box. Flipping the switch here opens doors on both the ground floor and the first floor.
- Cassette: Purrfect Grooves: Located on a shelf in the main living area.
Short Circuit: The Tilted Sconce
Short Circuit features some of the most "classic" video game secrets, involving environmental interactions.
| Secret Location | How to Access |
|---|---|
| The Tilted Sconce | Interact with the second wall lamp (sconce) on the left in the first-floor hallway. |
| Fridge Storage | Look for a tiny, inconspicuous door next to the refrigerator in the kitchen. |
| The Astronaut Box | (Nightmare Mode) Jump through the cracked window in the office to reach the exterior ledge. |
Italian Job: Pizzeria & Casino
To find crime scene cleaner all secrets in the Italian Job, you must look beneath the surface—literally.
- The Gambling Room: Go to the room left of the pizzeria entrance. Move the boxes under the dartboard to find a trapdoor. The key is located in the kitchen drawer.
- The Secret Concert: In the back alley, you will find a brick wall. You must use a ladder (either found nearby or from your skill tree) to climb over it. Behind the wall is a stage with a dead waitress and a cassette tape.
- Cassette: Swishi Swoop: Found on a drawer inside the hidden gambling room.
Affair with Death: The Villa Secrets
This level features a large outdoor area and a multi-story villa. Many secrets are tied to the basketball court and the basement.
- The Drug Corner: Go to the basketball court, climb the stairs, and follow the ledge to the corner. Under the tallest tree, you will find a stash of drugs and cash.
- Money Trolley: In the basement, look for a pile of boxes. Moving them reveals a crawlspace leading to a hidden room with a trolley full of money.
- The Laundry Room: The key is located on top of the toilet in the first-floor bathroom. Use it to open the laundry room on the ground floor.
Modern Art: The Museum Puzzles
Modern Art contains the most complex secret in the game, involving a color-matching puzzle and a legendary weapon.
The Katana Secret
- Enter the maze room through the dinosaur entrance.
- Look at the glass ceiling or the security monitors to see a specific color pattern.
- Navigate to the back of the maze where several monitors are located.
- Change the channels on the monitors to match the pattern from the ceiling.
- A wall will open, revealing a Katana. You must use this weapon to slice through mannequins to exit the room.
The Golden Cassette
In the concert hall (the room with the transparent cassette cases on the wall), you can actually climb the cases like a ladder. Reach the very top to find a golden cassette; interacting with it opens a secret door nearby.
Call in Dead: Industrial Secrets
The final main mission is an industrial labyrinth. Finding crime scene cleaner all secrets here requires careful platforming.
