A bone anomaly without a forged certificate is a normal rejection; call Security only when the day's rule explicitly ties that action to forged medical evidence.
On Bone Day, separate the anomaly decision from the forged-document decision. A current answered Steam discussion reports that a visitor who visibly reveals a metal skeleton but does not present a forged medical certificate should receive a normal rejection. Calling Security was counted as a mistake because the stronger action applied to a forged certificate, not merely to the anomaly.
Day 11 decision order
- Read the exact daily rule before processing the next visitor.
- Use the Bone MRI or visible evidence to determine whether a bone anomaly exists.
- Ask for and inspect the medical evidence required by the day's protocol.
- If the anomaly is present and no valid exception applies, deny entry.
- Use the Security action only when the separate condition named by the rule—such as a forged medical certificate—is actually satisfied.
The important distinction is evidence, not appearance. A visitor exposing an unusual arm proves the anomaly but does not automatically prove that a document was forged. Apply each consequence to its own trigger.
When the result still looks wrong
Capture the daily rule, MRI result, certificate status, visitor statement, action taken, and end-of-day penalty. Security 51 can combine several checks on later shifts, so do not import a Day 11 shortcut into a different rule set without rereading the protocol.
Current walkthroughs also warn that visitors can vary. Use the fixed rule and visible evidence rather than copying one person's visitor order. If a patch changes the wording, follow the current in-game text and report the changed build.
Return to the Security 51 guide hub or use the Shift Map guide after Day 30.

QUICK ANSWERS
Questions players ask next
What do I do with a bone anomaly on Security 51 Day 11?
Deny entry when the anomaly is present and there is no forged medical certificate. A current answered discussion distinguishes rejection from the separate forged-pass Security action.
Should I call Security for a visible metal skeleton?
Not solely because the anomaly is obvious. Apply the current rule to the documents actually presented; no forged pass means the forged-pass action does not apply.
