Security 51 Early Shifts Walkthrough

This early shifts walkthrough routes Security 51’s first in-game week on Steam — August 12, 2026 full release (App 4246860) and the free demo (App 4351470) where coverage overlaps. Alawar front-loads teaching: Start Day bulletins, passport fields, then behavioral horror before X-ray and biometrics dominate. Follow days sequentially while cross-reading Getting Started and Document Verification.

No promo codes accelerate days — only correct protocols advance your pay and unlock tools in Sanity and Supplies.

Day 1 — Tutorial shift

Goals: Learn drag compares, allow/deny buttons, elevator send.

• Press Start Day and read every bulletin line before visitors arrive.
• Verify name and ID on passport versus facility pass — details in Document Verification.
• Deny on clear mismatches; do not quarantine yet unless tutorial forces it.
• Count every elevator trip — seed habit for Elevator Headcount.

Fails to avoid: Allowing on name-only match, skipping photo glance even before photo rules tighten.

Day 2 — Photo awareness

Bulletins introduce photo compare emphasis. Compare face to document portrait before allow.

• Watch posture and speech per Spotting Anomalies — early rashes may appear as flavor before rules harden.
• Buy food if sanity dips after first mistakes.

Day 3 — Clearance and time windows

Passes now stress clearance level and appointment times.

• Janitors should not ride to deep floors without escort notations when bulletins require.
• Track groups as two bodies if escort plus visitor.

Day 4 — Photo mismatch traps

Community reports highlight days where instructions say allow on valid documents even when photos look wrong — read bulletin literally.

• Pair with Document Verification photo section.
• Use Verification Checklist photo line every visitor.

Day 5 — Medical certificates

Fake medical certs appear after tutorial updates in patch v0.0.1.105 — blurry stamps, wrong departments.

• Deny forged certs before infection mechanics accelerate.
• Note Launch Patch Notes if cert art changes again.

Day 6 — Longer queues

Playtest patches increased shift duration — more visitors, more fatigue.

• Keyboard shortcuts from Keyboard and Mouse matter.
• Eat before shift; budget in Sanity and Supplies.

Day 7 — First duplication hints

Employees may reappear after exit logs say they left — logical anomalies.

• Cross-check Elevator Headcount before allow.
• Consider quarantine introduction per Quarantine Protocol if tutorial unlocks detention.

After week one

Unlock paths toward X-Ray Scanning and Fingerprint and Blood Tests. Demo may end before full week — see Demo vs Full Game.

Track achievements in All Achievements once Steam badges populate post-launch. Story branches surface in Endings.

Daily universal checklist

1. Start Day — read bulletin
2. Documents — name, ID, photo, clearance, time
3. Body — anomalies scan
4. Elevator — headcount
5. Tools — only when rules or risk demand
6. Between shifts — food, upgrades, checklist reset

Compare tone with Security 51 vs Papers, Please — early shifts feel familiar until Day 4 photo traps and Day 7 duplication prove Alawar is not cloning Lucas Pope blindly.

Early shifts build the record the facility uses against you later. Route each day cleanly, cross-link guides when systems spike, and treat the walkthrough as spine — not substitute for reading tomorrow’s bulletin.
