Security 51 Checkpoint Rules

A source-bounded checklist for documents, permissions, times and headcounts at the Security 51 checkpoint.

Released factsLast checked

This page turns the verified premise into a repeatable checklist. It does not claim exact shift rules or thresholds that have not been published.

1. Verify the identity record

Compare the visitor's name, position and clearance level against the documents, pass or verbal instruction they provide. Note discrepancies before choosing an action.

2. Verify time and headcount

Check that the request matches the current time and that the number of people entering and leaving is consistent. Keep these fields visible instead of relying on memory.

3. Record the decision

When a case remains suspicious, quarantine is an official response. The exact consequences and decision thresholds require post-launch verification.

Evidence boundary: no complete “daily rules” list is published here. New examples must be tied to a current game version or official update.
