To find fingerprints in FORENSIC - M.E. Protocol, you must first visually inspect potential surfaces with your Alternate Light Source (ALS), select the correct powder (black for light surfaces, white for dark), and apply it gently with the appropriate brush. Once the latent print is visible, photograph it for evidence, then carefully press a hinge or gel lifter over it to collect the sample for analysis. This core loop is the difference between a passing grade and a perfect score on your final case evaluation.
Mastering this process is non-negotiable. While the early cases in the game are forgiving, later investigations like "Case File 04: The Alchemist's Debt" will fail you for a single smudged print. This guide breaks down every tool, technique, and common pitfall.
What's In Your Fingerprinting Kit?
Your success starts before you ever dust a surface. Choosing the wrong tool for the job is the fastest way to destroy evidence. Your standard-issue kit contains a variety of powders, brushes, and lifters, each with a specific purpose. Ignoring their designated uses is a rookie mistake the game will punish you for.
Choosing the Right Powder
The fundamental rule is contrast. You want the print to stand out against the surface it’s on. Your kit provides three main types of powder, and picking the right one is your first critical decision.
| Powder Type | Primary Use | Best Surfaces | Worst Surfaces |
|---|---|---|---|
| Black Carbon | Light-colored, non-porous surfaces | White countertops, glass, polished silver, painted walls | Dark wood, black plastic, untreated paper |
| White Titanium | Dark-colored, non-porous surfaces | Dark glass, gunmetal, black leather, dark vehicle paint | Light-colored paper, white tile, mirrors |
| Magnetic | Textured or delicate surfaces | Grained plastic, glossy paper, styrofoam, some fabrics | Metal surfaces (interferes with magnet), wet surfaces |
The key takeaway is to always observe the surface color and texture before opening a powder jar. Using Black Carbon on a dark mahogany desk, for example, will make the print completely invisible, forcing you to either abandon the evidence or incur a penalty for contamination.
Brushes and Applicators
How you apply the powder is just as important as which powder you choose. Using the wrong brush can wipe a delicate print out of existence.
- Camel Hair Brush: This is your soft, all-purpose brush for applying Black and White powders to smooth, flat surfaces. Use a light, twirling motion. Do not press down; let the weight of the bristles do the work.
- Fiberglass Wand: A more specialized brush for when you need an even lighter touch. Its long, fine filaments are excellent for developing faint prints on glass or polished metal without smearing the delicate ridge detail.
- Magnetic Wand: This applicator is used exclusively with Magnetic Powder. It never actually touches the surface. You hover the wand tip over the area, and the magnetic field makes the powder gently dance across the surface, adhering to the oils of the latent print. This is the only safe method for fragile surfaces like glossy magazine covers.
Lifting and Preserving
Once a print is developed and photographed, you need to collect it. Your kit includes two primary tools for this.
- Hinge Lifters: These are essentially specialized pieces of transparent tape with a backing card. They are your workhorse for lifting prints from flat, smooth surfaces. You press the adhesive side over the print, smooth out any bubbles, and peel it back to transfer the powdered print.
- Gel Lifters: These are thick, pliable gelatin slabs designed for curved or textured surfaces where tape would fail. A Gel Lifter can conform to the contours of a doorknob, a firearm grip, or a textured vase, pulling the entire print cleanly. They are more expensive in the game's economy, so save them for when they're truly necessary.
The Step-by-Step Fingerprinting Protocol
Follow this sequence meticulously on every single print. The game tracks your adherence to protocol, and skipping steps will lower your final score, even if you successfully identify the suspect.
Step 1: Visual Inspection with the ALS
Before you touch anything, equip your Alternate Light Source. Cycle through the different wavelengths (colors) as you scan surfaces like light switches, door frames, windows, and table tops. The ALS will cause oils and biological residue to fluoresce, revealing the likely location of latent prints that are invisible to the naked eye. Mark at least three potential sites before proceeding.
Step 2: Selecting and Applying Powder
Based on your visual inspection, choose a target. Assess the surface color and texture, then select the appropriate powder and applicator from your kit. The technique is crucial: do not simply paint the powder on. Lightly dip the very tips of your brush in the powder, tap off any excess, and use gentle, circular motions from a distance, allowing the powder to settle onto the print. You should see the ridges slowly appear; if the entire area turns into a gray or black smudge, you've used too much pressure or powder.
Step 3: Photographing the Developed Print
This is the most commonly missed step by new players. Before you lift the print, you MUST take a photograph. Equip your evidence camera, make sure the print is in focus and well-lit, and include a scale marker in the shot. The game's UI will show a green checkmark on the "Photograph Evidence" objective. If you lift the print first, you cannot go back, and you will lose critical points for improper procedure.
Step 4: The Perfect Lift
Choose your lifter (Hinge for flat, Gel for curved/textured). Anchor one end of the tape or gel next to the print, not on it. Then, smoothly roll it over the powdered print in a single, confident motion. Use your thumb to gently press out any air bubbles, as these will create blank spots in your collected evidence. Once it's fully adhered, peel it back slowly from one corner. The powdered print should now be perfectly transferred to your lifter, ready to be sealed and sent to the lab for analysis.

Advanced Techniques for Difficult Surfaces
Later in the game, you'll encounter surfaces that don't respond to standard powders. For these, you'll need to unlock and use chemical techniques. These are typically unlocked after completing "Case File 05: The Marionette's Maker."
Porous Surfaces: Paper and Untreated Wood
Prints on items like letters, cardboard, or raw wood have soaked into the surface. Powder won't work. For these, you'll need to use chemical fuming in the mobile lab.
- Ninhydrin Spray: For paper and cardboard. The item is placed in a fuming chamber, and the spray reacts with amino acids in the fingerprint sweat, turning the print a distinct purple color over time.
- Iodine Fuming: Best for raw, untreated wood or certain types of paper. The iodine crystals are heated, and their vapors adhere to the fatty oils in the print, temporarily staining it a brownish color. You must photograph it quickly, as the print will fade.
Handling Bloody or Wet Prints
Never try to powder a print left in blood or another liquid. This will destroy it. Instead, you must use a chemical stain. The primary one you'll unlock is Amido Black, a protein stain that turns bloody prints a dark blue-black, making them clearly visible against the background for photography.
Common Mistakes That Will Ruin Your Evidence
We see the same errors again and again from cadets rushing through their crime scenes. Avoid these at all costs.
- Over-powdering: The most common error. A mountain of powder smudges the print, destroying the fine ridge details (minutiae) needed for a positive ID. Less is always more.
- Contrast Catastrophe: Using black powder on a dark surface or white powder on a light one. This renders the print invisible and wastes valuable time.
- Forgetting the Photo: Lifting a print before you've photographed it in situ is an automatic and severe penalty on your evaluation. The photograph preserves the context of where the print was found.
- Hasty Lifting: Ripping the lifting tape off like a bandage. This can tear the tape, create air bubbles, and distort the print, making it useless for the matching algorithm.

Frequently Asked Questions
Why isn't my powder sticking to the print? This usually means one of three things: the print is too old and has degraded, it was left on an incompatible surface (like rough fabric), or it's a wet print that requires chemical treatment instead of powder.
Can you lift the same print twice? No. The lifting process removes the powder and the oils that made up the print. You get one shot per print, which is why following the protocol perfectly is so important.
How do I unlock chemical fuming techniques? These advanced tools like Ninhydrin and Amido Black are unlocked through story progression. You'll gain access to them after successfully completing major case files, typically starting around Case File 05.
Does the angle of the ALS matter? Yes, absolutely. Holding the Alternate Light Source at a low, oblique angle (almost parallel to the surface) will cause the ridges of a print to cast small shadows, making them much easier to spot. Experiment with different angles.
The Final Word
Fingerprinting in FORENSIC - M.E. Protocol is a microcosm of the entire game: it's not about speed, but about deliberate, methodical precision. Every print is a puzzle. By internalizing the correct protocol—observe, select, apply, photograph, lift—you turn a frustrating mini-game into a reliable source of case-breaking evidence. Don't rush it. The details matter, and the game rewards you for treating the evidence with the respect it deserves.
