Professional cleaning for the underworld isn't just about mopping up blood; it is about precision, discretion, and perfection. To truly excel, players must master the crime scene cleaner scoring system guide to ensure they receive the highest payouts and best ratings from their "employers." Whether you are scrubbing floors in a suburban home or managing a massive industrial warehouse, your final grade depends on a variety of factors including cleaning thoroughness, item placement, and evidence collection.

This comprehensive crime scene cleaner scoring system guide will break down the mechanics behind your final mission report. We will explore how to achieve a 100% clean rating, where to find elusive clues, and how to handle complex missions like "Call In Dead" to maximize your efficiency. By the end of this guide, you will have the tools needed to turn a grisly murder scene into a pristine environment that would pass any forensic inspection.

Understanding the Core Scoring Categories

The scoring system in Crime Scene Cleaner evaluates your performance across several distinct metrics. While the primary goal is obviously to remove all traces of a crime, the game rewards players who go above and beyond the basic requirements.

CategoryImpact on Final GradeDescription
Cleaning PercentageHighThe total amount of blood, grime, and footprints removed from the scene.
Trash DisposalMediumCollecting all garbage, broken glass, and discarded items into bags and bins.
Evidence/CluesHighFinding specific items related to the narrative of the crime.
Furniture RestorationLowPlacing moved or knocked-over furniture back into its original or logical position.
Body DisposalCriticalEnsuring all remains are removed or processed according to mission parameters.

💡 Tip: Always use your UV light (or "Cleaner Sense") frequently. Even a tiny speck of blood hidden under a rug can prevent you from reaching a 100% cleaning score.

How the Crime Scene Cleaner Scoring System Guide Works

To achieve an S-Rank, you must balance speed with meticulous attention to detail. The crime scene cleaner scoring system guide emphasizes that while time is a factor in some bonus objectives, your thoroughness is the most significant contributor to your grade. Most missions require at least a 95% cleaning threshold to pass, but the perfectionist will aim for 100% and all collectibles.

The Cleaning Percentage

The game tracks every pixel of blood. Using the power washer for large areas and the mop for delicate surfaces is essential. If you find your score stuck at 99%, check the ceilings and the undersides of tables. Footprints are also a common culprit for missed spots; if you walk through blood and then onto a clean floor, you are creating more work for yourself.

Evidence and Narrative Clues

Clues are not just for flavor; they are essential for your final score. Each mission has a set number of clues—usually telephones, notes, or digital devices—that explain what happened at the scene. Missing even one clue can drop your grade significantly, even if the room is spotless.

Mission Spotlight: "Call In Dead" Scoring Strategy

The final mission, "Call In Dead," is one of the most complex challenges in the game. It takes place in a large industrial area with multiple floors, conveyors, and cranes. To get a perfect score here, you must navigate a series of power puzzles and keycard requirements.

Keycard Locations and Power Management

In "Call In Dead," you cannot have all systems active at once. You are limited to three active panels. Managing the power supply is crucial for accessing the areas where clues and secrets are hidden.

Keycard ColorLocationFunction
GreenFirst Floor, on the conveyor belt.Activates basic conveyor systems.
BlueFirst Floor, behind a mini-game door.Used for hatch control and access.
OrangeNear the first floor "dude" (NPC).Essential for activating the elevator.
YellowSecond Floor, obtained via elevator.Operates the crane for container movement.

Finding the 4 Essential Clues

In "Call In Dead," there are four clues you must collect to satisfy the crime scene cleaner scoring system guide requirements for narrative completion.

  1. Phone 1: Located on the main floor, easily accessible near the start.
  2. Phone 2: On the second floor; requires the elevator to be powered (Orange Keycard).
  3. The Board: Located in the crane area; requires jumping across containers.
  4. Container Clue: Inside a specific container that must be lowered by the crane.

Secrets and Cassettes: The Completionist's Edge

While not strictly part of the "cleaning" score, finding secrets and cassettes provides a massive boost to your overall profile and unlockable content. In the "Call In Dead" mission, there are five secrets and four cassettes hidden throughout the warehouse.

Secret Room Locations

  • Secret 1: Accessible right at the start by jumping through a series of vents and pipes near the entrance.
  • Secret 2: Requires the "Room Key" found near the power supply. This opens a hidden office containing the first cassette.
  • Secret 3: On the second floor, requires a platforming sequence to reach a safe. You may need to use tools like the Katana or Axe to break through barriers.
  • Secret 4: Located behind a "hidden wall" near the power supply area where you meet a "crazy blend guy."
  • Secret 5: The "Unknown Room," which requires the Unknown Key found in a crane-accessible container and specific power settings (Hatch power on).

Cassette Checklist

  1. Cassette 1: Inside Secret Room 2.
  2. Cassette 2: Found in the main office area on the second floor.
  3. Cassette 3: Hidden on the left-side container in the crane bay.
  4. Cassette 4: Located inside the final secret room (Secret 5).

Advanced Tips for S-Rank Performance

To consistently hit high marks in the crime scene cleaner scoring system guide, you should optimize your loadout before starting a mission. Upgrading your mop's absorbency and the power washer's reach will save you significant time.

  • Don't Forget the Trash: Every piece of trash left behind is a penalty. Use the trash bags efficiently and ensure they are thrown into the designated disposal bin or your truck.
  • Stealing vs. Professionalism: While you can find cash and valuables at crime scenes, be aware that excessive looting can sometimes impact your "Professionalism" rating, though it helps your financial progression.
  • The "No Cleaning" Run: In certain missions like "Call In Dead," it is possible to collect all clues and secrets without doing the cleaning first. This is a great way to scout the map before committing to a deep clean.

Warning: Be careful when moving heavy objects. Knocking over a bucket of dirty water will create a massive mess, instantly undoing several minutes of progress and tanking your efficiency score.

FAQ

Q: Does the time taken to complete a mission affect the Crime Scene Cleaner scoring system?

A: In the current 2026 version of the game, time does not directly penalize your base score, but completing missions quickly can earn you "Speed" bonuses and higher placement on global leaderboards.

Q: What happens if I miss a single clue in a mission?

A: Missing a clue usually prevents you from achieving an S-Rank. Most missions require 100% clue discovery for the highest possible grade.

Q: Can I go back and clean areas after finishing the main objectives?

A: Yes, as long as you haven't interacted with your vehicle to "Leave Scene," you can continue cleaning and searching for secrets. It is highly recommended to do a final sweep with the UV light before departing.

Q: Are cassettes required for a 100% clean rating?

A: No, cassettes and secrets are considered "Collectibles." They contribute to your overall completion percentage but are tracked separately from your cleaning and clue-finding score. However, for a "Perfect" run, most players aim to collect everything.
