Security 51 Bone MRI Guide: Sharp Bones & Certificates

Quick answer

Use the bone MRI only when it is available and the active rule requires an internal bone check. Confirm the scan against the current reference image or manual, then apply the response for that shift.

Sharp Bone evidence

For Sharp Bone checks, look for bones that are visibly thinner and end in sharper points than the normal reference. If the rule asks for a certificate tied to a specific bone, click the suspicious bone itself, then match it with the anomaly icon on the computer before asking for the certificate.

Certificate workflow

1. Scan the skeleton with Bone MRI.
2. Compare the suspicious area with the Manual image.
3. Click the exact bone segment, not just the body area.
4. Match the selected bone to the anomaly icon on the computer.
5. Ask for the medical certificate when the current order requires one.
6. Apply the day's rule: forged certificates usually escalate to Security, while real anomalies may still require denial depending on the order.

Avoid false certainty

The unlock day and exact response can vary by build or order. Treat the in-game manual as authoritative and record the current rule in your Daily Rules notes.
