Security 51 Shift Map — What to Do After Day 30

FAST ANSWER

The Shift Map changes an earlier campaign branch after Day 30; it is separate from Endless Mode and the Easy, Medium, or Hard choice available only when starting a new game.

Finish Day 30 and its story scene; the game then opens the Shift Map and teaches you how to alter earlier outcomes. Two launch walkthroughs independently describe the same sequence: the normal day report is replaced by a cutscene, the elevator takes you to an unfamiliar area, a hologram explains that the law must be rewritten, and the branching-timeline tutorial begins.

First Shift Map pass

1. Complete the Day 30 shift and continue through the entire cutscene.
2. Follow the Shift Map tutorial when the interface opens automatically.
3. Choose one of the available earlier outcomes the tutorial allows you to manipulate.
4. Continue from that altered branch instead of replaying the same choice unchanged.
5. Use the new outcome to advance the investigation into the BSODeaD hacker group.

The Shift Map is therefore not a conventional next-day selector. It changes the timeline after the first 30-day route. Visitor queues can vary, so the useful target is the decision outcome shown on the map rather than another walkthrough author's exact visitor order or earnings.

Shift Map, new game, and Endless Mode are different

• Shift Map: revisit an earlier campaign branch after Day 30 and alter a decision or outcome.
• New game: choose Easy, Medium, or Hard. Existing saves remain on Medium and do not gain a difficulty selector.
• Endless Mode: continue through unlimited shifts until sanity or hunger is fully depleted.

Tool upgrades are connected to the player profile and persist across repeat playthroughs. That does not convert an old save to a different difficulty; it means earned upgrades can carry into another run. The publisher recommends starting a new game to experience all new update changes, but the official note does not instruct players to delete their current campaign.

What “start fresh from the branch” means

The instruction to start again from a branch means that progression has changed from consecutive shifts to alternate outcomes. Repeating every previous choice would leave that branch unchanged; the tutorial is asking you to alter an available decision and follow the result.

For named final outcomes, use the separate ending guide. This page covers interface setup, not an all-endings route. The two release walkthroughs checked here both stop after explaining the Shift Map unlock. They do not provide a reproducible list of ending names and exact triggers. For that reason, this page does not pretend to be an all-endings guide.

The September 3 randomized-replay note specifically concerns Endless Mode events. It does not say that changing a campaign branch is the same operation. For the wider mode boundaries, use difficulty and upgrade rules.

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