Security 51 X-Ray Scanning Guide

X-ray scanning is Security 51’s mid-shift power spike — and its mid-shift liability. After you survive early paperwork in Document Verification and body screening from Spotting Anomalies, Alawar grants a scanner that reveals silhouettes, contraband, and shapes that should not fit inside a human outline. Used correctly, X-ray confirms hunches before you quarantine or deny. Used blindly, it wastes time, drains sanity, and still misses logical anomalies from Elevator Headcount.

Unlock the scanner through shift progression and purchase when Sanity and Supplies budgeting allows. The full Steam game (App 4246860) positions X-ray after foundational shifts; demo players may see limited access — check Demo vs Full Game.

When bulletins require scans

Not every visitor needs X-ray every day. Bulletins add rules such as:

• Mandatory scan for specific floors or departments.
• Scan when external anomalies are visible but documents pass.
• Skip scan when instructions emphasize document-only decisions.

Photo-match traps still apply: some days allow entry on valid paperwork even when photos fail. X-ray does not override bulletin hierarchy — it adds another layer when authorized.

Reading silhouettes

Learn normal outlines first: tool belts, clipboards, standard lab gear. Anomalies show extra limbs, voids, dense masses where lungs should be, objects that should not enter certain levels.

Compare silhouette with visible behavior. A visitor who refuses to stand square might hide asymmetry visible on scan. Pair with Fingerprint and Blood Tests when silhouettes suggest infection but IDs remain clean.

Contraband items — weapons, unauthorized samples, smuggled containers — appear as hard shapes. Deny or quarantine per Quarantine Protocol when contraband violates floor policy.

Time and queue management

Scans take precious seconds while the elevator waits. During long post-patch shifts, queue length grows. Use Keyboard and Mouse shortcuts to cycle tools quickly.

If visitors stack, prioritize scans for high-risk profiles: solo riders to deep floors, staff with behavioral flags, repeat faces from duplication events.

Low sanity slows reactions — eat before marathon scan days per Sanity and Supplies.

X-ray versus camera lies

X-ray shows body contents, not elevator occupancy. Cameras that claim empty cars while someone stands inside are headcount problems, not scanner problems. Do not assume the scanner replaces Elevator Headcount discipline.

Similarly, X-ray cannot prove identity — only contents and gross morphology. Biometrics still matter for staff who look right on scan but wrong on fingerprint.

Common player mistakes

• Scanning everyone when bulletins do not require it — wastes time and pay.
• Ignoring scan when behavioral tells stack — misses cheap confirms.
• Denying on ambiguous silhouettes without quarantine option — sometimes detention is safer per Quarantine Protocol.
• Forgetting Start Day bulletin changes after Launch Patch Notes retune rules.

Learning path

1. Getting Started — tool unlock timing.
2. Early Shifts Walkthrough — first scan days.
3. Verification Checklist — scan line item.
4. Security 51 vs Papers, Please — comparative tone on body horror tools.

X-ray is the game’s clearest Papers, Please evolution: Lucas Pope rarely asked you to irradiate a janitor. Here, the scanner is bureaucratic protocol weaponized into horror. Respect bulletins, respect silhouettes, and never let the beam substitute for counting who steps off the elevator.
