To correctly place evidence markers in FORENSIS - M.E. Protocol, you must first scan a potential clue with your Multi-Function Tool to confirm it's relevant, then place a numbered marker directly beside the object's center of mass. The key is methodical confirmation before placement, as the game penalizes you for marking irrelevant items, misplacing markers, or exhausting your limited supply on red herrings. Getting this right is the single most important factor in achieving the coveted 'Master Investigator' rank.
This guide breaks down the entire procedure, from the fundamental principles to advanced strategies for the game's most complex crime scenes. We'll cover the common mistakes that cost players their perfect score and detail the precise mechanics the game's evaluation system uses to judge your performance.
The Core Principles of Evidence Marking
Unlike many detective games where you simply click on everything that glows, FORENSIS - M.E. Protocol demands precision. The game operates on a strict philosophy: a forensic specialist doesn't just find things; they correctly identify, isolate, and document them without contaminating the scene or wasting resources. Your primary tools are your eyes, your Multi-Function Tool (MFT), and a limited set of numbered evidence markers.
The final evaluation score you receive at the end of each case is directly tied to your marker efficiency. The system grades you on three primary criteria:
- Relevance: Did you only mark items pertinent to the case? Marking a random coffee cup or a discarded newspaper will incur a penalty.
- Accuracy: Is the marker placed correctly next to the evidence, not on top of it or a foot away? Poor placement can result in a score deduction.
- Completeness: Did you identify and mark all key pieces of evidence required to solve the case?
Simply finding every clue isn't enough. A perfect run requires that you find all relevant clues, ignore all irrelevant distractions, and place each marker with near-surgical precision. Wasting even one or two markers on a false lead can be the difference between a standard 'Investigator' rank and the top tier.

Let's break the process down into its component parts. Following this sequence every single time will build the muscle memory needed for the high-pressure scenarios in later cases.
Step 1: The Initial Visual Sweep
When you first enter a crime scene, resist the urge to immediately start placing markers. Do a slow, methodical walkthrough of the area. Get a sense of the layout, the points of entry and exit, and the general state of the scene. Look for obvious signs of a struggle, discarded objects, or anything that seems out of place. This initial, tool-free observation phase is crucial for building a mental map of the event.
Step 2: Confirming Evidence with the MFT Scanner
Once you've identified a potential piece of evidence—a shell casing, a dropped keycard, a footprint—do not immediately place a marker. Instead, equip your Multi-Function Tool and aim it at the object. A successful scan will provide a brief description in your HUD, confirming the item's relevance. For example, scanning a pistol will identify it as a '9mm Handgun, Model G-19'. If the scanner gives you a generic reading like 'Debris' or 'Container', it's a red herring. If it doesn't get a specific ID, do not mark it.
Step 3: Precise Marker Placement
With the evidence confirmed, you can now place a marker. The goal is to place the marker's base as close to the object's center of mass as possible without touching or obscuring it. A good rule of thumb is to leave a sliver of visible space between the marker and the evidence. Placing a marker directly on top of a small object like a bullet can actually penalize you for obscuring the evidence itself.
For larger objects like a body or a piece of furniture, place the marker at a logical point of interest—next to a wound on a body, or near the point of forced entry on a door. The game is generally forgiving with larger items, but precision is always rewarded.

Step 4: Documenting and Linking Evidence
After placing a marker, your case file is automatically updated with a new entry. It's good practice to mentally note the number and its corresponding piece of evidence. In more complex cases, you'll need to understand how different pieces of evidence connect. Marker #3 (a footprint near the window) might logically connect to Marker #7 (a muddy handprint on the windowsill). While the game doesn't have a manual linking system, making these connections in your own mind is key to solving the overarching puzzle of the crime.
Common Mistakes That Will Tank Your Score
Many players struggle to get a perfect score because of a few common, repeatable errors. Avoiding these pitfalls is essential for mastering the protocol.
- The Trigger-Happy Marker: This is the number one mistake. New players often place a marker as soon as they see something that looks suspicious, without scanning it first. The crime scenes are intentionally littered with red herrings. Remember the rule: scan first, mark second. Always.
- Clustering and Occlusion: Placing markers too close together can result in a 'Clustering' penalty. Each piece of evidence needs its own distinct space. Furthermore, never place a marker in a way that it blocks the view of another piece of evidence. For example, placing a marker for a footprint in a way that it hides a tiny shell casing right behind it is a critical error.
- Wasting Your Finite Supply: You typically start a mission with only 10-15 markers. Wasting them on irrelevant objects can leave you without a marker when you discover a critical piece of evidence later in the investigation. If you run out of markers before the scene is complete, a perfect score is impossible.
- Ignoring Environmental Clues: Evidence isn't just objects you can pick up. It's also blood spatter on the wall, scuff marks on the floor, or a broken window latch. These require the same scan-and-mark procedure and are often the most-missed clues by new investigators.

Advanced Techniques for Complex Scenes
Later cases, like the multi-floor investigation in the 'C-Block Contagion' level, introduce more complex variables. Here, basic marking isn't enough; you need to think like a real investigator.
One key challenge is evidence with multiple components. A smashed laptop, for instance, might have three distinct points of interest: the broken screen, the detached battery, and the damaged keyboard. The game's logic dictates you mark the primary object—the laptop chassis itself. Marking each individual fragment is a waste of markers and will likely incur a penalty. Scan the main body of the object to get the primary ID.
Another advanced technique involves 'pathing' your markers. In scenes with a clear sequence of events, like a trail of bloody footprints, placing your markers in a logical numerical order (e.g., Marker 1 at the start of the trail, Marker 2 at the next print, and so on) helps create a coherent narrative of the crime. While the scoring system doesn't explicitly reward this, it's a professional habit that prevents you from becoming disoriented and missing a step in the sequence.

Finally, pay close attention to your MFT's alternate scanning modes. Some evidence is not visible to the naked eye and requires you to switch to thermal or UV light. A seemingly clean floor might reveal chemical residue or biological traces under the correct filter. Sweeping every scene with all available scanner modes is non-negotiable for achieving a 100% completion rate.
Understanding Your Final Evaluation Score
At the end of every mission, you'll receive a detailed performance review. This screen breaks down your score and assigns you a rank. Understanding what it means is key to improving your approach.
The score is primarily based on the percentage of correctly identified evidence minus penalties for any mistakes. The ranks are a direct reflection of your adherence to the forensic protocol.
| Rank | Accuracy Score | Common Marker Errors | Notes |
|---|---|---|---|
| Trainee | 0-49% | 5+ errors | Missed critical evidence, marked multiple red herrings. |
| Investigator | 50-79% | 2-4 errors | Found most key evidence but made placement or relevance mistakes. |
| Senior Investigator | 80-94% | 1 error | All critical evidence found, with one minor placement mistake. |
| Master Investigator | 95-100% | 0 errors | A perfect, textbook execution of forensic protocol. |
As you can see, the margin for error is razor-thin. A single misplaced or wasted marker is enough to knock you out of the running for the 'Master Investigator' rank, which is often tied to in-game achievements and unlockables.
Frequently Asked Questions (FAQ)
Can you pick up and move an evidence marker in FORENSIS? No. Once a marker is placed, its position is final for that attempt. If you make a significant error early on, it is often better to restart the mission than to continue with a flawed investigation record.
How many evidence markers do you get per level? This varies depending on the complexity of the case, but the number is always finite and typically ranges from 10 to 15. The UI displays your remaining marker count, so keep a close eye on it.
Does the order in which you place markers matter? The final score is not directly affected by the numerical order of your markers. However, placing them in a logical sequence that follows the flow of events can significantly improve your own analytical process and prevent you from missing clues.
What's the penalty for scanning a red herring? There is no penalty for simply scanning an irrelevant object. The penalty is only applied when you commit to the action and place a marker next to that irrelevant object. Scan freely; place deliberately.
The Final Takeaway
Mastering evidence marking in FORENSIS - M.E. Protocol is less about speed and more about discipline. The game rewards a slow, deliberate, and methodical approach. Trust your scanner, be economical with your markers, and treat every placement as if it's the one your entire case depends on—because it is.
