Security 51 Endings: Routes, Choices & Shift Map
Quick answer
Use the Security 51 endings hub to track confirmed routes, branch choices, the Shift Map, achievements, and anomaly pages without relying on unverified ending claims.
Security 51 endings index
This hub organizes the pages that help you plan ending and replay routes. The game is new, so the safest approach is to separate confirmed mechanics from community theory and keep notes on what your own save actually unlocks.
| Route or topic | Best starting point | Spoiler level |
|---|---|---|
| First clear | Complete walkthrough | Low |
| Branching after an ending | Shift Map guide | Medium |
| Choices and consequences | Decision guide | Partial |
| Isolation route | Isolation ending guide | Full |
| System Breakdown route | System Breakdown ending guide | Full |
| The Fool camera check | The Fool anomaly solution | Low |
| Completion cleanup | 68 Steam achievements | Medium |
What to do after your first ending
After you reach an ending, use the Shift Map instead of deleting your save. The August update made alternate-story branch days easier to read with question marks, borders, and tooltips, so check those markers before replaying a long section.
- Open the Shift Map.
- Pick the earliest branch marker connected to the route you want to test.
- Replay forward and change only the decision you are investigating.
- Record the ending, achievement unlock, and any route note that changed.
- Compare the result with the choices database.
How to track ending evidence
Use this table when updating your own notes or when checking community claims:
| Evidence type | Trust level | How to use it |
|---|---|---|
| Your own save result | Highest | Record the day, branch point, choice, and unlock |
| Steam achievement unlock | High | Confirms an outcome exists, but not always the exact trigger |
| Patch notes | High | Confirms mechanic changes and bug fixes |
| Steam discussion | Medium | Useful for hints, but verify before treating as route logic |
| Video clip without full context | Medium-low | Good for location clues, weak for branching requirements |
| Theory thread | Low | Keep separate from route instructions |
Common mistakes while chasing endings
- Changing several choices at once, then not knowing which one caused the new result.
- Replaying only the final day when the route depends on an earlier operation.
- Treating anomaly names as confirmed ending names.
- Ignoring achievements after a branch resolves.
- Following older screenshots without checking the current Shift Map markers.
Route checklist
Before committing to a replay route, make sure you have:
- Finished the initial Day 1-30 timeline.
- Opened the Shift Map and identified a branch marker.
- Checked the walkthrough hub for the relevant day range.
- Reviewed the Steam achievements guide for unlock clues.
- Kept anomaly pages separate from true ending routes unless the game confirms otherwise.
FAQ
How many endings does Security 51 have?
The exact count should be treated as unconfirmed unless the game, achievement list, or a verified save route proves it. This hub tracks confirmed guide pages and keeps speculative routes separate.
Do I need a new save for each ending?
Usually no. After the first ending, the Shift Map is designed for revisiting earlier branch points from the same save.
Is The Fool an ending?
Current evidence supports The Fool as a camera anomaly check. The existing URL is preserved because players search for it, but the page now explains the anomaly solution.
