The Shift Map is a replay tool for testing altered decisions after the Day 30 transition; change one branch at a time and compare the resulting hacker evidence.

After Day 30, use the Shift Map to revisit a meaningful decision, change one branch, and compare the resulting evidence. A current full-release walkthrough describes an elevator transition, a hologram conversation about rewriting the law, and a tutorial that introduces the branching timeline. The goal is not to replay random shifts; it is to identify which altered decisions expose the BSODead hacker group and lead to a different outcome.

First Shift Map pass

  1. Finish the Day 30 transition and read the complete tutorial.
  2. Identify the earliest highlighted decision point available to change.
  3. Record the original action and its immediate outcome.
  4. Change only that decision for the next pass.
  5. Follow the resulting branch far enough to see whether evidence, rules, or the ending state changes.
  6. Add the result to a simple branch log before editing another point.

Changing several decisions at once makes it impossible to know which one produced the new route. A useful log includes the shift, exact action, immediate result, later consequence, and ending connection.

What “start fresh from the branch” means

Current community questions describe confusion after the first ending because the game asks the player to return to a branch. Treat that return as a controlled alternate-timeline test, not as a demand to repeat everything identically. Choose a decision that can plausibly change hacker identification, facility policy, or a later rule, then compare the result.

This page does not claim a complete ending matrix. Existing public guides disagree on route labels, and community names are not always official. Keep any unverified ending name separate from the actual visible outcome.

Use the Bone Day guide for Day 11's medical-pass distinction, or return to the Security 51 guide for the current answer map.

When does the Security 51 Shift Map unlock?

Current full-game walkthrough evidence places the branching-timeline tutorial after completing Day 30 and its transition scene.

Do I need to start a completely new save for another branch?

The Shift Map is presented as the tool for manipulating earlier decisions and testing other outcomes, so use it before creating a separate save.
