Alter Ego: The Laboratory Fuse Puzzle
The "Alter Ego" mission introduces a complex laboratory environment where you must restore power to proceed with the cleanup. This requires finding four specific fuses scattered throughout the facility.
How to Find the 4 Fuses
- Fuse 1: Located directly in the room with the four sockets. It is sitting on a desk near the entrance of the fuse room.
- Fuse 2: In the room with the elevated ladder. You must move a body or a crate to jump onto the ledge, then climb the ladder to find the fuse on the upper walkway.
- Fuse 3: This is the most difficult. Go to the electric chair room. You will find a locked box. To open it, you must find the "Electricity Item" located on the upper floor (accessible via the elevator). Bring this item back, plug it into the wall by the chair, and activate the chair to pop the box open.
- Fuse 4: Take the elevator up and head to the left. Follow the hallway to the end of the balcony area where the fourth fuse is resting on a table.
Call In Dead: Final Mission Walkthrough
The "Call In Dead" level is a massive industrial area that serves as the game's final challenge. Achieving a perfect score here requires careful management of keycards and environmental puzzles.
Keycard Locations
To navigate the warehouse and office spaces, you will need several access cards.
| Keycard Type | Location |
|---|---|
| Conveyor Belt | Found in the hands of a worker caught in the machinery. |
| Hatch Keycard | Located in the office space adjacent to the control room. |
| Elevator Keycard | Sitting on top of a box in the sorting room. |
| Crane Keycard | Descend the ladder from the second-floor office balcony. |
Secrets in Call In Dead
- Secret 1: Look for a breakable vent in the power supply room. Crawling through leads to a hidden stash.
- Secret 2: In the ground floor hall, stack boxes to reach the metal rafters. Duck under the obstructions to find the secret at the end of the path.
- Secret 3: Climb the lockers in the control room to reach the overhead pipes. Follow the pipes into a hidden vent.
- Secret 4: Find the key in the small room near the elevator. Use it to open the TV room in the power supply area (marked by a cardboard cutout).
- Secret 5: Use the crane to move the blue container. Cross over to the other side to find an "Unknown Key" inside a second container. This opens a locked door at the start of the conveyor belt area.
Essential Cleaning Tools & Upgrades
As you progress through your crime scene cleaner walkthrough, you will earn skill points to upgrade your gear. Prioritizing the right tools makes the difference between a 30-minute job and an hour-long struggle.
- The Power Washer: Essential for outdoor areas and large blood splatters. Upgrade for better pressure and lower water consumption.
- Ozone Machine: Used to remove the "smell" of the crime scene. Place this once all bodies and trash are removed.
- Luminol Spray: Vital for finding "invisible" blood stains that prevent a 100% score.
- The Ladder: Unlock this in the skill tree as soon as possible. It is required for several secrets in the "Italian Job" and "Affair With Death" missions.
⚠️ Warning: Breaking items (vases, electronics, furniture) will lower your deception score. Use the "Smooth Operator" approach by moving furniture carefully before mopping.
Achievement Hunting Tips
For players looking to complete the Crime Scene Cleaner Steam Achievements, several "hidden" tasks must be performed across multiple levels.
- Petting Dexter: You can pet your dog, Dexter, in your home apartment between missions. Petting him 15 times unlocks "Happy Together."
- The Toaster Incident: Around mission 4 or 5, a toaster will spawn in your kitchen. Take it to the bathroom and drop it in the tub to earn the "Electric Feel" achievement.
- Bóbr k*rw@!: In the "Bad Call" mission, you must smash two wooden planks back-to-back on your first try using your fists.
- Money, Money, Money: You must steal a total of $50,000 across all missions. This is cumulative, so keep an eye out for wallets, watches, and cash stacks hidden in drawers.
FAQ
Q: How do I get a 100% deception score in every mission?
A: To achieve a perfect score, you must remove all trash, clean 100% of blood stains (use the Luminol spray to find hidden ones), dispose of all bodies, and return all key items to their original positions. Avoid breaking any environmental objects.
Q: Where is the last tape in the Modern Art mission?
A: The fourth tape is located on the first floor of the North Exhibition. You must go through the "Duck Room" and take the staircase up; the tape is sitting in the middle of the hallway.
Q: Can I replay missions to find missed secrets?
A: Yes, you can access the mission select screen from your computer in the home apartment. Replaying missions is the best way to farm money for the "Money, Money, Money" achievement and find any missed collectible tapes.
Q: What is Nightmare Mode in Crime Scene Cleaner?
A: Nightmare Mode is an advanced difficulty where players must find hidden music discs instead of tapes. The environments are darker, and the cleaning requirements are more stringent, requiring absolute mastery of the game's mechanics.
