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 Day 11, deny entry for a bone anomaly. Call Security only when the medical certificate is forged. Two separately authored launch walkthroughs give the same rule order. A matching Steam discussion describes the exact trap: a visitor exposed a metal skeleton, but calling Security counted as a mistake because no forged certificate had been shown.
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.
Why another player's visitor list can mislead you
The launch walkthrough warns that visitors are randomized. Use the Day 11 instruction hierarchy and the evidence on your own visitor, not a copied name or queue order. Later shifts use different bone rules, so this answer applies to Day 11 only.
If your live instruction sheet differs after a patch, follow the wording shown in the game. The important distinction remains between the condition that causes denial and the separate condition that upgrades the action to calling Security.
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.
